Abstract
Reducing the allergenicity of edible insects is crucial for the comprehensive utilization of insect resources. Phospholipase A2 (PLA2) exists in various edible insects and mammalian tissues, which can cause serious allergic reactions. Herein, we constructed a magnetic nanocomposite with photo/chemical synergistic capability to mitigate the allergenicity of PLA2. The formation of prepared nanocomposite was systematically confirmed using various techniques. The nanocomposite exhibited uniform diameters, abundant functional groups, excellent magnetic capabilities. An effective photo/chemical method was established to reduce the allergenicity of PLA2 in vitro. The feasibility of the method was demonstrated through circular dichroism, fluorescence spectrum and IgE-binding analysis. The allergenicity and IgE-binding effect of PLA2 were significantly reduced due to conformational changes after nanomaterial treatment. These results demonstrate the sensitivity and effectiveness a strategy for reducing PLA2 allergenicity, providing a basis for development of nanomaterials to reduce the risk of novel food allergies in response to edible insect products.

An Assessment of the Impact of Insect Meal in Dry Food on a Dog with a Food Allergy: A Case Report. Animals (Basel) 2024; 14:2859. [PMID: 39409808 PMCID: PMC11476448 DOI: 10.3390/ani14192859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2024] [Revised: 09/25/2024] [Accepted: 09/26/2024] [Indexed: 10/20/2024] Open
Abstract
Food allergy triggers an immune response to dietary proteins, resulting in food rejection and dermatological and gastrointestinal manifestations. The preferred therapies include diets with hydrolyzed proteins or unusual single-source proteins, with insect protein emerging as a promising option, with no reported allergic reactions in dogs with a food allergy. In this case study, the effects of including black soldier fly larva (BSFL) meal were observed in a 5-year-old spayed beagle previously diagnosed with a food allergy. The objective was to assess the potential of BSFL meal as an adjunct in treating a food allergy. As part of the protocol, two nutritionally very similar diets were used, differing only in the protein source: the control diet, with poultry by-product meal; and the BSFL diet, which completely replaced the poultry by-product meal. After a 12-day adaptation period to the BSFL diet, the dog showed no gastrointestinal changes, maintaining an adequate fecal score and no clinical signs of the disease. A challenge test with the control diet resulted in episodic gastrointestinal symptoms, which were reversed within two days by reintroducing the BSFL diet. The BSFL protein-based diet was effective in controlling the dog's clinical signs.

Food Chem 2024; 454:139781.

Abstract
The amount of chitin, a nitrogen-containing dietary fiber, in edible insects can mislead the exact nitrogen-to-protein conversion factor (NPF) and true protein content. We determined the amino acid score (AAS), protein digestibility-corrected AAS (PDCAAS), chitin content, and net NPF of five edible insects. Additionally, the effect of the amino acid composition of migratory locust on rat growth were investigated. The AAS of the insects were ranged from 63 to 94. The chitin contents were ranged from 1.6 g/100 g to 10.7 g/100 g. The PDCAAS, calculated by AAS and gut-intestinal digestibility, ranged from 44 to 81, which was lower than casein (97). The net NPF ranged from 4.93 to 5.76, which were lower than the conventional value. Dietary migratory locust, whose PDCAAS was the lowest, decreased growth and altered lipid metabolism. Therefore, a lower PDCAAS and overestimation of net NPF of insects can affect the true protein calculations and growth.

Abstract
PURPOSE OF REVIEW Diets low in animal-source foods or solely consisting of plant-based foods, hardly meet nutrition needs of children, exposing them to inadequate intake of essential nutrients. Thus, including edible insects in children's diets is relevant for meeting nutritional requirements, other potential health benefits, and building more sustainable food systems. Nutrition and health research on insects is novel and still limited. This review covers recently published research between April 2022 and November 2023 focusing on the relevance of including insects in children's diets. RECENT FINDINGS Insects provide protein, fat and micronutrients, and are generally nutritionally equivalent to animal-source foods. The protein and fat quality of edible insects varies depending on several factors. Insects also contain chitin which could potentially be beneficial for gut health. For insects to be considered suitable for inclusion in children's diet, they must be accepted. However, children who are unfamiliar with insects respond to them with curiosity and disgust. SUMMARY Insect farming can enhance their availability and consumption, potentially addressing nutrition gaps. Furthermore, transitioning from occasional to regular insect consumption requires actual exposure and integration into diets of insects. To affirm the nutrition and health potential of edible insects for children, well designed human studies are essential.

Abstract
The exploration of edible insects, specifically Alphitobius diaperinus and Tenebrio molitor, as sustainable sources of protein for human consumption is an emerging field. However, research into their effects on intestinal health, especially in relation to inflammation and permeability, remains limited. Using ex vivo and in vivo models of intestinal health and disease, in this study we assess the impact of the above insects on intestinal function by focusing on inflammation, barrier dysfunction and morphological changes. Initially, human intestinal explants were exposed to in vitro-digested extracts of these insects, almond and beef. Immune secretome analysis showed that the inflammatory response to insect-treated samples was comparatively lower than it was for samples exposed to almond and beef. Animal studies using yellow mealworm (Tenebrio molitor) and buffalo (Alphitobius diaperinus) flours were then used to evaluate their safety in healthy rats and LPS-induced intestinal dysfunction rats. Chronic administration of these insect-derived flours showed no adverse effects on behavior, metabolism, intestinal morphology or immune response (such as inflammation or allergy markers) in healthy Wistar rats. Notably, in rats subjected to proinflammatory LPS-induced intestinal dysfunction, T. molitor consumption did not exacerbate symptoms, nor did it increase allergic responses. These findings validate the safety of these edible insects under healthy conditions, demonstrate their innocuity in a model of intestinal dysfunction, and underscore their promise as sustainable and nutritionally valuable dietary protein sources.

Abstract
Presently, there has been an increase in the consumption of the blue-green microalga-spirulina (Arthrospira species), which dominates 99.5% of the total world production of microalgae. Primarily sold as a dietary supplement, it is also incorporated into snacks, pasta, cookies, and bread. Owing to its nutrient abundance, spirulina has a variety of potential applications. Extensive studies have been conducted on the health benefits of spirulina, but its safety in terms of allergy has received limited attention. Therefore, to bridge this knowledge deficit, this review aimed to evaluate the allergenic and antiallergic potential of spirulina. In the PubMed and Scopus databases using words related to allergy, we attempted to detect papers on hypersensitivity to spirulina. A total of 128 records were identified, of which 49 were screened. Ultimately, in this review, we analyzed four case studies, encompassing a total of five patients with allergies to spirulina. We assessed the severity of allergic reactions following World Allergy Organization (WAO) Anaphylaxis Guidance 2020, which varied from mild (grade 2) to severe (grade 4) based on the patient's symptoms. Additionally, our findings indicate that allergy to spirulina is not commonly reported or diagnosed. However, most of the described cases (four of five) regarding allergy to spirulina according to WAO Anaphylaxis Guidance 2020 were classified as anaphylaxis. Furthermore, it is noteworthy that spirulina also possesses antiallergic properties, as evidenced by research studies. Our article delves into both the allergic and antiallergic potential of spirulina.

Abstract
SCOPE Edible insects contain allergens with potential cross-reactivity to other invertebrates. Here, this study examines IgE-reactive proteins in a house cricket snack (Acheta domesticus) leading to an allergic reaction in a 27-year old man followed by a similar reaction days later after eating shrimps. METHODS AND RESULTS Prick to prick tests verify the IgE-mediated allergy to crickets and skin prick testing confirms a type I sensitization to house dust mite without any clinical relevance for the patient, and to shrimp extracts, but is negative for several other foods. Serological testing reveals a sensitization to shrimps, shrimp tropomyosin, and house dust mite tropomyosin. IgE-immunodetection shows that the cricket allergic patient is sensitized to two proteins of 45 and >97 kDa using aqueous control cricket extract, but to only one protein at around 45 kDa when using the causative, seasoned insect snack extract. Mass spectrometry data and IgE-inhibition experiments clearly identify this protein belonging to the tropomyosin allergen family. CONCLUSION This case report suggests that cricket tropomyosin may be an elicitor of allergic reactions even in previously not allergic patients, although it cannot be excluded the patient reacted additionally to other ingredients of the snack.

Abstract
Edible insects have been proposed as an environmentally and economically sustainable source of protein, and are considered as an alternative food, especially to meat. The migratory locust, Locusta migratoria, is an edible species authorised by the European Union as a novel food. In addition to their nutritional value, edible insects are also sources of bioactive compounds. This study used an in silico approach to simulate the gastrointestinal digestion of selected L. migratoria proteins and posteriorly identify peptides capable of selectively inhibiting the N-subunit of the somatic angiotensin-I converting enzyme (sACE). The application of the molecular docking protocol enabled the identification of three peptides, namely TCDSL, IDCSR and EAEEGQF, which were predicted to act as potential selective inhibitors of the sACE N-domain and, therefore, possess bioactivity against cardiac and pulmonary fibrosis.

NPJ Sci Food 2024; 8:7.

Abstract
Food consumption play a crucial role in human life, yet conventional food production and consumption patterns can be detrimental to the environment. Thus, research and development has been directed towards alternative proteins, with edible insects being promising sources. Edible insects have been recognised for their sustainable benefits providing protein, with less emission of greenhouse gas, land and water usage compared to sources, such as beef, chicken, and dairy products. Among the over 2000 known edible insect species, only four, namely yellow mealworm (Tenebrio molitor), migratory locust/grasshopper (Locusta migratoria), grain mould beetle, also known as lesser mealworm which is a larval form of Alphitobius diaperinus (from the family of Tenebrionidae of darkling beetles) and house cricket (Acheta domesticus), are currently authorised in specific products through specific producers in the EU. The expansion of such foods into Western diets face challenges such as consumer barriers, gaps in microbiological and chemical safety hazard data during production and processing, and the potential for fraudulent supply chain activity. The main aim of this study was to map the supply chain, through interviews with personnel along the supply chain, coupled with searches for relevant publications and governmental documents. Thus, the main potential points of food safety and fraud along the edible insect supply chain were identified. Feed substrate was identified as the main area of concern regarding microbiological and chemical food safety and novel processing techniques were forecast to be of most concern for future fraudulent activity. Despite the on-going authorisation of insect species in many countries there are substantial food safety and authenticity information gaps in this industry that need to be addressed before edible insects can be viewed as a safe and sustainable protein sources by Western consumers.

Abstract
As the world population rises, the demand for protein increases, leading to a widening gap in protein supply. There is an unprecedented interest in the development of alternative proteins, but their allergenicity has raised consumer concerns. This review aims to highlight and correlate the current research status of allergenicity studies on alternative proteins based on previously published studies. Current research keywords, hotspots and trends in alternative protein sensitization were analyzed using a mixed-method approach that combined bibliometric analysis and literature review. According to the bibliometric analysis, current research is primarily focused on food science, agriculture, and immunology. There are significant variations in the type and amount of allergens found in alternative proteins. A significant amount of research has been focused on studying plant-based proteins and the cross-reactivity of insect proteins. The allergenicity of alternative proteins has not been studied extensively or in depth. The allergenicity of other alternative proteins and the underlying mechanisms warrant further study. In addition, the lack of a standardized allergy assessment strategy calls for additional efforts by international organizations and collaborations among different countries. This review provides new research and regulatory perspectives for the safe utilization of alternative proteins in human food systems.

Abstract
Increased interest in consumption of insects in recent years has led to an increased focus on associated food safety concerns, and allergy is one of the most relevant. In the United States, crustacean shellfish are regulated as a major allergenic food group per the Food, Drug, and Cosmetic (FD&C) Act. Insects and crustacean shellfish are both arthropods, and clinical cross-reactivity between the two groups has been demonstrated. The goal of this work was to establish whether that clinical cross-reactivity translates into analytical cross-reactivity with detection assays targeting crustacean shellfish allergens. Edible insect samples were analyzed using four different crustacean allergen detection methods: Multi-Analyte Profiling Food Allergen Detection Assay (xMAP FADA), enzyme-linked immunosorbent assay (ELISA), western blot, and real-time polymerase chain reaction (PCR). Results indicate that the immunoassay-based xMAP FADA, ELISA, and western blot were susceptible to cross-reactivity, while the DNA-based PCR methods had minimal reactivity with insect samples. These results confirm that edible insects show analytical cross-reactivity with the immunoassays which may result in false positive detection of crustacean allergens in insect samples. Confirmation using DNA-based PCR, which shows little to no cross-reactivity, clarifies ambiguous results.

Molecular detection of Imbrasia belina proteins associated with allergic reactions on harvesters and consumers from selected districts in Matabeleland: a comparative study. Mol Biol Rep 2023; 50:8025-8034. [PMID: 37540454 DOI: 10.1007/s11033-023-08678-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 07/13/2023] [Indexed: 08/05/2023]
Abstract
BACKGROUND Harvesting and consuming insects (entomophagy), particularly Imbrasia belina is widespread in developing countries like Zimbabwe. Due to their extraordinary nutritional content, tastiness, ease of processing and storage, Imbrasia belina has become a delicacy, reachable nutritious complement, and money source for some people in Zimbabwean communities. However, some harvesters and consumers have become allergic to the Imbrasia belina, popularly known as Mopani worms. This has been attributed or associated with the changes in the genetic structure of Imbrasia belina. Therefore, this research sought to compare the presence of the genes associated with allergic reactions to mopane worms from Gwanda and Umguza districts in Zimbabwe. METHODS A lab-based observational study was conducted on collected Imbrasia belina samples from both districts. Fifteen samples of mopane worms were collected from each district, and DNA extraction was performed using DNeasy blood and tissue kit. The DNA extraction products were then amplified using a Polymerase chain reaction. The polymerase chain reaction products were run on agarose gel electrophoresis to determine the presence of the target genes. RESULTS Three of the five samples from Gwanda district were positive for the tropomyosin gene, whereas two samples from Umguza district were positive. All the samples from the two districts were negative for arginine kinase genes. CONCLUSION The study results highlighted that allergic reactions to Imbrasia belina reported in Gwanda district are associated with the presence of the tropomyosin gene, which has undergone polymorphism. Responsible authorities such as Gwanda local authority should develop bylaws that govern Imbrasia belina harvesting in the district.

Abstract
This review aims to provide an updated overview of edible insect proteins and the bioactivity of insect-derived peptides. The essential amino acid content of edible insects is compared with well-known protein sources to demonstrate that edible insects have the potential to cover the protein quality requirements for different groups of the population. Then the current methodologies for insect protein extraction are summarized including a comparison of the protein extraction yield and the final protein content of the resulting products for each method. Furthermore, in order to improve our understanding of insect proteins, their functional properties (such as solubility, foaming capacity, emulsifying, gelation, water holding capacity and oil holding capacity) are discussed. Bioactive peptides can be released according to various enzymatic hydrolysis protocols. In this context, the bioactive properties of insect peptides (antihypertensive, antidiabetic, antioxidant and anti-inflammatory properties) have been discussed. However, the allergens present in insect proteins are still a major concern and an unsolved issue for insect-based product consumption; thus, an analysis of cross reactivity and the different methods available to reduce allergenicity are proposed. Diverse studies of insect protein hydrolysates/peptides have been ultimately promoting the utilization of insect proteins for future perspectives and the emerging processing technologies to enhance the wider utilization of insect proteins for different purposes.

Abstract
Insects have been consumed as food in diverse cultures worldwide, gaining recognition as a sustainable and nutritious food source. This systematic review aims to update information on the impact of insect consumption on human health based on human randomized controlled trials (RCTs) and allergenicity assessment studies. Following PRISMA guidelines, studies published in the last 10 years were analyzed. From one-thousand and sixty-three retrieved references, nine RCTs and five allergenicity studies were analyzed. Post-prandial amino acid levels increased after insect protein consumption. In comparison with other protein sources, insect protein showed no significant differences in the area under the curve (AUC) values for essential amino acids but tended to have lower peaks and peak later. In terms of muscle protein synthesis, there were no significant differences between insect protein and other protein sources. Glucose levels did not differ; however, insulin levels were lower after the consumption of insect-based products. The effects on inflammatory markers and microbiota composition were inconclusive and the studies did not show significant effects on appetite regulation. Allergenicity assessments revealed a sensitisation and cross-reactivity between insect allergens and known allergens. A partial reduction of cross-allergenicity was observed via thermal processing. Insect protein is an adequate protein source with promising health benefits; however, further research is needed to fully understand its potential and optimise its inclusion into the human diet.

Abstract
Edible insect products contain high-quality protein and other nutrients, including minerals and fatty acids. The consumption of insect food products is considered a future trend and a potential strategy that could greatly contribute to meeting food needs worldwide. However, insect proteins have the potential to be allergenic to insect consumers. In this review, the nutritional value and allergy risk of insect-derived foods, and the immune responses elicited by insect allergens are summarized and discussed. Tropomyosin and arginine kinase are the most important and widely known insect allergens, which induce Th2-biased immune responses and reduced the activity of CD4+T regulatory cells. Besides, food processing methods have been effectively improving the nutrients and characteristics of insect products. However, limited reviews systematically address the immune reactions to allergens present in edible insect proteins following treatment with food processing technologies. The conventional/novel food processing techniques and recent advances in reducing the allergenicity of insect proteins are discussed in this review, focusing on the structural changes of allergens and immune regulation.

Abstract
The practice of entomophagy is common in Asia, Africa, and South America and is now spreading to Europe and the United States. Entomophagy is not without risk since humans can develop allergic reactions to the ingested insects. Here we describe a case of anaphylaxis after consumption of Polistes olivaceus larvae in a 23-y-old man living in Reunion Island, a French overseas department where wasps and other insects are occasionally consumed as part of local traditions. The patient developed diffuse pruritus with facial edema, nausea, and vomiting 15 min after ingesting pan-fried wasp larvae during a dinner with two other people. He was taken to a local care center where he received two oral doses of antihistamines. Shortly after, he presented with shock and hemodynamic, respiratory, and neurological failure. He received a subcutaneous injection of adrenaline and was rapidly transferred to hospital for 12 h of monitoring, after which he was discharged without sequelae. The patient's anaphylactic reaction may have been due only to the allergens contained in the ingested larvae or to cross-allergy. To our knowledge, this is the first reported case of anaphylaxis after consumption of Polistes olivaceus larvae. More generally, few cases of allergic reaction to ingested insects have been described in the literature.

Abstract
Since the discovery of immunoglobulin E (IgE) as a mediator of allergic diseases in 1967, our knowledge about the immunological mechanisms of IgE-mediated allergies has remarkably increased. In addition to understanding the immune response and clinical symptoms, allergy diagnosis and management depend strongly on the precise identification of the elicitors of the IgE-mediated allergic reaction. In the past four decades, innovations in bioscience and technology have facilitated the identification and production of well-defined, highly pure molecules for component-resolved diagnosis (CRD), allowing a personalized diagnosis and management of the allergic disease for individual patients. The first edition of the "EAACI Molecular Allergology User's Guide" (MAUG) in 2016 rapidly became a key reference for clinicians, scientists, and interested readers with a background in allergology, immunology, biology, and medicine. Nevertheless, the field of molecular allergology is moving fast, and after 6 years, a new EAACI Taskforce was established to provide an updated document. The Molecular Allergology User's Guide 2.0 summarizes state-of-the-art information on allergen molecules, their clinical relevance, and their application in diagnostic algorithms for clinical practice. It is designed for both, clinicians and scientists, guiding health care professionals through the overwhelming list of different allergen molecules available for testing. Further, it provides diagnostic algorithms on the clinical relevance of allergenic molecules and gives an overview of their biology, the basic mechanisms of test formats, and the application of tests to measure allergen exposure.

Monitoring Yellow Mealworm ( Tenebrio molitor) as a Potential Novel Allergenic Food: Effect of Food Processing and Matrix. Nutrients 2023; 15:nu15030482. [PMID: 36771191 PMCID: PMC9921270 DOI: 10.3390/nu15030482] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 01/12/2023] [Accepted: 01/14/2023] [Indexed: 01/19/2023] Open
Abstract
The consumption of insects has increased in western countries, raising concerns about their potential to induce food allergic reactions in sensitized/allergic individuals. This work intended to develop a real-time PCR approach for the detection/quantification of yellow mealworm (Tenebrio molitor) as a potential allergenic food in complex matrices. For this purpose, reference mixtures simulating the production of pork sausages and wheat biscuits containing known amounts of mealworm were used. Real-time PCR with TaqMan probe targeting the cytochrome b gene of T. molitor was able to detect up to 2 fg of insect DNA, and 1.0 and 0.1 mg/kg of mealworm flour in autoclaved sausages and baked biscuits, respectively. Generally, the method showed acceptable analytical performance parameters, confirming its suitability/applicability for a wide range of foods. However, real-time PCR data showed significant differences among food matrix and processing, highlighting the importance of using appropriate calibration models for quantitative analysis. Finally, the real-time PCR approach was successfully validated with blind mixtures and applied to commercial samples, demonstrating its efficacy and reliability in the quantification of mealworm in processed foodstuffs.

Abstract
Despite the increasing popularity of crustacean shellfish among consumers due to their rich nutrients, they can induce a serious allergic response, sometimes even life-threatening. In the past decades, a variety of crustacean allergens have been identified to facilitate the diagnosis and management of crustacean allergies. Although food processing techniques can ease the risk of crustacean shellfish allergy, no available processing methods to tackle crustacean allergies thoroughly. Strict dietary avoidance of crustacean shellfish and its component is the best option for the protection of sensitized individuals, which should rely on the compliance of food labeling and, as such, on their verification by sensitive, reliable, and accurate detection techniques. In this present review, the physiochemical properties, structure aspects, and immunological characteristics of the major crustacean allergens have been described and discussed. Subsequently, the current research progresses on how various processing techniques cause the alterations and modifications in crustacean allergens to produce hypoallergenic crustacean food products were summarized and discussed. Particularly, various analytical methodologies employed in crustacean shellfish allergen detection, and the effect of food processing and matrix on these techniques, are also herein emphasized for the appropriate selection of analytical detection tools to safeguard consumers safety.

Abstract
Many protein families have numerous members listed in databases as allergens; however, some allergen database entries, herein called "orphan allergens", are members of large families of which all other members are not allergens. These orphan allergens provide an opportunity to assess whether specific structural features render a protein allergenic. Three orphan allergens [Cladosporium herbarum aldehyde dehydrogenase (ChALDH), Alternaria alternata ALDH (AaALDH), and C. herbarum mannitol dehydrogenase (ChMDH)] were recombinantly produced and purified for structure characterization and for clinical skin prick testing (SPT) in mold allergic participants. Examination of the X-ray crystal structures of ChALDH and ChMDH and a homology structure model of AaALDH did not identify any discernable epitopes that distinguish these putative orphan allergens from their non-allergenic protein relatives. SPT results were aligned with ChMDH being an allergen, 53% of the participants were SPT (+). AaALDH did not elicit SPT reactivity above control proteins not in allergen databases (i.e., Psedomonas syringae indole-3-acetaldehyde dehydrogenase and Zea mays ALDH). Although published results showed consequential human IgE reactivity with ChALDH, no SPT reactivity was observed in this study. With only one of these three orphan allergens, ChMDH, eliciting SPT(+) reactions consistent with the protein being included in allergen databases, this underscores the complicated nature of how bioinformatics is used to assess the potential allergenicity of food proteins that could be newly added to human diets and, when needed, the subsequent clinical testing of that bioinformatic assessment.Trial registration number and date of registration AAC-2017-0467, approved as WIRB protocol #20172536 on 07DEC2017 by WIRB-Copernicus (OHRP/FDA Registration #: IRB00000533, organization #: IORG0000432).

Abstract
Although edible insect migratory locusts are considered sustainable food resources with proteins and n-3 lipids, their physiological effects on lipid metabolism are not clarified. Here, we clarified the amino acid (AA) value of the edible migratory locust powder (MLP), protein digestibility, and dietary effects of MLP on growth and lipid metabolism in rats. The AA score was 63, which was low score due to the limiting AA (Trp). MLP protein digestibility was resistant to gut pepsin but digestible to intestinal trypsin and chymotrypsin. Dietary MLP represented favorable growth and enhanced intestinal condition and lipid metabolism in rats, particularly, low-density lipoprotein metabolism and arteriosclerosis-related fatty acid profiles. Liver triglyceride accumulation and fatty acid desaturation indices were increased by activating lipids uptake into the liver, while lipogenic protein expression and enzyme activities and liver function indices were reduced by MLP. Conclusively, intestinal digestible MLP is a nutraceutical for the prevention of dyslipidemia.

Abstract
The demand for meat alternatives has been growing in the recent years and it is expected to keep expanding. Motives driving this growth are diverse and are mostly related to the health and ethical concerns over animal welfare and the possible impact of meat production on the environment. Meat alternatives are not anymore a niche market (i.e., vegetarians and vegans) but going mainstream (also consumed by meat eaters and flexitarians). This can be attributed to advances in formulations and ingredients and innovative technologies resulting in improved quality of products. This chapter summarizes the current knowledge about meat alternatives (from plant, fungi or/and algae). Plant-based alternatives are already a proofed commodity with a wide range of products available in the market. The search for more sustainable sources had put the spotlight on other sources such as fungi and algae due to their limited need to land, energy and water for biomass production. Fungi-based alternatives are steps ahead of those algae-based owing to fungi neutral flavor, comparable nutritional profile to meat and no need to masking agents. Consumer acceptance is still a key challenge boosting research and development efforts to ensure a better quality, affordability, and sustainability.

Abstract
The Food and Agriculture Organization of the United Nations (FAO) estimates that more than 500 million people, especially in Asia and Africa, are suffering from malnutrition. Recently, livestock farming has increased to supply high-quality protein, with consequent impact on the global environment. Alternative food sources with high nutritive values that can substitute livestock demands are urgently required. Recently, edible crickets have been promoted by the FAO to ameliorate the food crisis. In this review, the distribution, nutritive values, health-promoting properties (antioxidant, anti-inflammatory, anti-diabetic and anti-obesity), safety, allergenicity as well as the potential hazards and risks for human consumption are summarized. Cricket farming may help to realize the United Nations sustainable development goal No. 2 Zero Hunger. The sustainability of cricket farming is also discussed in comparison with other livestock. The findings imply that edible crickets are safe for daily intake as a healthy alternative diet due to their high protein content and health-promoting properties. Appropriate use of edible crickets in the food and nutraceutical industries represents a global business potential. However, people who are allergic to shellfish should pay attention on cricket allergy. Thus, the objective of this review was to present in-depth and up-to-date information on edible crickets to advocate and enhance public perception of cricket-based food.

Recognizing Potential Pathways to Increasing the Consumption of Edible Insects from the Perspective of Consumer Acceptance: Case Study from Finland. SUSTAINABILITY 2022.

Abstract
Mitigating the sustainability challenges related to agriculture and ensuring adequate availability of nutritious food requires an increase in the use of sustainable alternative protein sources. Edible insects are considered to be a sustainable protein source and a possible substitute for meat. There are many readily available edible insect species with many competing utilization possibilities, which, from the producers’ perspective, increases the complexity of the area. Through a consumer survey and expert interviews, this study recognizes four pathways to increasing the use of edible insects in Western countries and especially in Finland where the survey and interviews were conducted: (1) producing a variety of insect-based food products, especially food products where insects are not recognizable as such and the food is in a familiar form; (2) producing edible insect food products which could replace greenhouse gas emission-intensive animal proteins; (3) focusing on the price, taste, and availability of insect food; and (4) using insects as animal feed. Our findings provide information on the prospects of the studied pathways in terms of consumption and production. Technological development is expected to decrease the price of insect-based food products, but at the same time, the increased use of edible insects faces challenges related to eating habits, contradictory perceptions about the sustainability implications of insect farming, and the availability of insect-based products.
