Effect of hydroxytyrosol, Moringa, and spirulina on the physicochemical properties and nutritional characteristics of gluten-free brownies. Food Sci Nutr 2024; 12:385-398. [PMID: 38268863 PMCID: PMC10804121 DOI: 10.1002/fsn3.3778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 10/06/2023] [Accepted: 10/07/2023] [Indexed: 01/26/2024] Open
Abstract
Brownies, enriched with fiber and Moringa oleifera, hydroxytyrosol (HXT), and spirulina (encapsulated and nonencapsulated), and dietary fiber using psyllium were elaborated. For that, a commercial control (CTRL) and an experimental control (CTRL) (without antioxidants) were compared. Color, nutritional composition, pH, antioxidant capacity, total phenolic compounds, as well as sensory properties were evaluated. The results showed the brownies developed with psyllium and the different extracts increased total dietary fiber compared to CTRL Commercial and CTRL, with E-spirulina (14.93 g/100 g) and Moringa (11.91 g/100 g) being the most prominent samples. However, with regard to soluble fiber, the highest content of NE-spirulina and the lowest content of HXT were observed. In addition, brownies enriched with extracts showed higher antioxidant capacity and higher phenolic compounds than controls, with HXT standing out at 299.25 μM Trolox/g in ABTS, 1470.08 μM Trolox/g in DPPH, and 18.15 μM Trolox/g in FRAP. However, a high level of phenolic compounds was found in E-Spirulina (604.71 mg/L). In reference to fatty acids, monounsaturated fatty acids (MUFA) (70%) were the predominant fatty acids, followed by polyunsaturated fatty acids (PUFA) (19%) and saturated fatty acids (SFA) (10%). Glutamic acid and asparagine were the predominant amino acids. As for mineral content, N-spirulina and E-spirulina were the brownies with the highest iron bioaccessibility; Si, Na, B, Al, P, Fe, Zn, Bi, Ca, Cu, Mg, Mn, Rb, S, and Sr being the most abundant elements in the brownies of this study. In addition, the HXT and Moringa samples scored higher in overall acceptability compared to the controls. The findings suggest that the incorporation of psyllium, quinoa flour, and antioxidant extracts in brownies could be a viable approach to produce a healthy brownie enriched with fiber, antioxidants and, therefore, considering the nutritional, physicochemical, and organoleptic characteristics, HTX is the ideal compound to enrich bakery products.

Applications of Plant Bioactive Compounds as Replacers of Synthetic Additives in the Food Industry. Foods 2023; 13:47. [PMID: 38201075 PMCID: PMC10778451 DOI: 10.3390/foods13010047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 12/11/2023] [Accepted: 12/17/2023] [Indexed: 01/12/2024] Open
Abstract
According to the Codex Alimentarius, a food additive is any substance that is incorporated into a food solely for technological or organoleptic purposes during the production of that food. Food additives can be of synthetic or natural origin. Several scientific evidence (in vitro studies and epidemiological studies like the controversial Southampton study published in 2007) have pointed out that several synthetic additives may lead to health issues for consumers. In that sense, the actual consumer searches for "Clean Label" foods with ingredient lists clean of coded additives, which are rejected by the actual consumer, highlighting the need to distinguish synthetic and natural codded additives from the ingredient lists. However, this natural approach must focus on an integrated vision of the replacement of chemical substances from the food ingredients, food contact materials (packaging), and their application on the final product. Hence, natural plant alternatives are hereby presented, analyzing their potential success in replacing common synthetic emulsifiers, colorants, flavorings, inhibitors of quality-degrading enzymes, antimicrobials, and antioxidants. In addition, the need for a complete absence of chemical additive migration to the food is approached through the use of plant-origin bioactive compounds (e.g., plant essential oils) incorporated in active packaging.

Development of Functional Gluten-Free Sourdough Bread with Pseudocereals and Enriched with Moringa oleifera. Foods 2023; 12:3920. [PMID: 37959040 PMCID: PMC10650811 DOI: 10.3390/foods12213920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 10/18/2023] [Accepted: 10/23/2023] [Indexed: 11/15/2023] Open
Abstract
Celiac patients tend to have an unbalanced diet, because gluten-free products typically contain a high amount of fats and carbohydrates and a low amount of proteins, minerals, and dietary fiber. This research focused on the development of gluten-free functional breads using pseudocereals, psyllium, and gluten-free sourdough to replace commercial yeast, fortifying them with Moringa oleifera. Six different gluten-free breads were made with sourdough: three control breads differentiated by sourdough (quinoa, amaranth, and brown rice) and three breads enriched with moringa leaf differentiated by sourdough. The antioxidant capacity, phenolic compounds, nutritional composition, physicochemical parameters (color, pH, and acidity), folate content, amino acid profile, reducing sugars, mineral composition, mineral bioaccessibility, fatty acid profile, and sensory acceptability were evaluated. A commercial gluten-free (COM) bread was included in these analyses. Compared with COM bread, the reformulated breads were found to have better nutritional properties. Moringa leaf increased the nutritional properties of bread, and highlighted the QM (quinoa/moringa) bread as having increased protein, fiber, sucrose, glucose, maltose, phenylalanine, and cysteine. The AM (amaranth/moringa) bread was also shown to have a higher total folate content, antioxidant capacity, phenolic compounds, 9t,11t-C18:2 (CLA), and 9t-C18:1. Reformulated breads enriched with moringa could meet nutritional requirements and provide health benefits to people with celiac disease.

Control of the Growth of Listeria monocytogenes in Cooked Ham through Combinations of Natural Ingredients. Foods 2023; 12:3416. [PMID: 37761125 PMCID: PMC10528306 DOI: 10.3390/foods12183416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/01/2023] [Accepted: 09/11/2023] [Indexed: 09/29/2023] Open
Abstract
In the ready-to-eat food industry, Listeria control is mandatory to ensure the food safety of the products since its presence could cause a disease called listeriosis. The objective of the present study was to carry out a challenge test to verify the efficiency of different combinations of natural antimicrobial ingredients against Listeria monocytogenes to be used in ready-to-eat foods. Six different formulations of cooked ham were prepared: a control formulation and five different formulations. An initial inoculation of 2 log cycles was used in the different products, and the growth of Listeria was monitored at different temperatures and times (4 °C for 17 w and 7 °C for 12 w). Control samples showed a progressive growth, reaching 5-6 log after 3 or 4 weeks. The rest of the samples showed constant counts of Listeria during the entire study. Only samples containing 100 ppm nitrite + 250 PPM ascorbic acid + 0.7% PRS-DV-5 did not control the growth of Listeria at 7 °C after 7 w of storage. The results obtained allowed us to classify the cooked ham prepared using natural ingredient combinations as a "Ready-to-eat food unable to support the growth of L. monocytogenes other than those intended for infants and for special medical purposes".

Abstract
Propolis is a natural hive product collected by honeybees from different plants and trees. The collected resins are then mixed with bee wax and secretions. Propolis has a long history of use in traditional and alternative medicine. Propolis possesses recognized antimicrobial and antioxidant properties. Both properties are characteristics of food preservatives. Moreover, most propolis components, in particular flavonoids and phenolic acids, are natural constituents of food. Several studies suggest that propolis could find use as a natural food preservative. This review is focused on the potential application of propolis in the antimicrobial and antioxidant preservation of food and its possible application as new, safe, natural, and multifunctional material in food packaging. In addition, the possible influence of propolis and its used extracts on the sensory properties of food is also discussed.

Abstract
Moringa oleifera belongs to the Moringaceae family and is the best known of the native Moringa oleifera genus. For centuries, it has been used as a system of Ayurvedic and Unani medicine and has a wide range of nutritional and bioactive compounds, including proteins, essential amino acids, carbohydrates, lipids, fibre, vitamins, minerals, phenolic compounds, phytosterols and others. These characteristics allow it to have pharmacological properties, including anti-diabetic, anti-inflammatory, anticarcinogenic, antioxidant, cardioprotective, antimicrobial and hepatoprotective properties. The entire Moringa oleifera plant is edible, including its flowers, however, it is not entirely safe, because of compounds that have been found mainly in the root and bark, so the leaf was identified as the safest. Moringa oleifera is recognised as an excellent source of phytochemicals, with potential applications in functional and medicinal food preparations due to its nutritional and medicinal properties; many authors have experimented with incorporating it mainly in biscuits, cakes, brownies, meats, juices and sandwiches. The results are fascinating, as the products increase their nutritional value; however, the concentrations cannot be high, as this affects the organoleptic characteristics of the supplemented products. The aim of this study is to review the application of Moringa oleifera in bakery products, which will allow the creation of new products that improve their nutritional and functional value.

Abstract
Natural extracts obtained from fruits and vegetables processing are important sources of phenolic compounds and nitrates, with excellent antioxidant and antimicrobial properties. The aim of this study was to elaborate a Clean label dry-cured meat product (Spanish "chorizo") using Mediterranean Diet ingredients (Citrus, Acerola, Rosemary, Paprika, Garlic, Oregano, Lettuce + Arugula + Watercress, Spinach + Celery, Chard + Beet). For that, a self-life study for 150 days was carried out, when physical-chemical (colour, pH, aw, thiol loss, volatile compounds profile), microbiological, and organoleptic changes were determined. The combination of citrus extracts and leafy green vegetables halved the hexanal and nonanal content for 150 days. In addition, this change did not affect to the sensory properties of the product, which obtained the highest acceptance avoiding the oxidative damage (colour, volatile compounds release, thiol loss) and the microbiological growth. Nevertheless, rosemary extract incorporation altered sensory quality, unless it also avoided protein and lipid oxidation, as well as microbiological growth. Otherwise, Control sample elaborated with synthetic sources of nitrates and nitrites showed a lower sensory quality due to the increased hardness, protein oxidation, hexanal, and nonanal concentrations, related to lipid oxidation, and hence, to rancid flavour apparition.

Seaweeds as a Functional Ingredient for a Healthy Diet. Mar Drugs 2020; 18:E301. [PMID: 32517092 PMCID: PMC7345263 DOI: 10.3390/md18060301] [Citation(s) in RCA: 111] [Impact Index Per Article: 27.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 06/02/2020] [Accepted: 06/02/2020] [Indexed: 12/22/2022] Open
Abstract
Seaweeds have been used since ancient times as food, mainly by Asian countries, while in Western countries, their main application has been as gelling agents and colloids for the food, pharmaceuticals, and the cosmetic industry. Seaweeds are a good source of nutrients such as proteins, vitamins, minerals, and dietary fiber. Polyphenols, polysaccharides, and sterols, as well as other bioactive molecules, are mainly responsible for the healthy properties associated with seaweed. Antioxidant, anti-inflammatory, anti-cancer, and anti-diabetic properties are attributed to these compounds. If seaweeds are compared to terrestrial plants, they have a higher proportion of essential fatty acids as eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids. In addition, there are several secondary metabolites that are synthesized by algae such as terpenoids, oxylipins, phlorotannins, volatile hydrocarbons, and products of mixed biogenetic origin. Therefore, algae can be considered as a natural source of great interest, since they contain compounds with numerous biological activities and can be used as a functional ingredient in many technological applications to obtain functional foods.

Abstract
The efficacies of Agrobacterium radiobacter K84 and K1026 in root colonization, crown gall control, and plasmid transfer were compared. Levels of root colonization by K84 and K1026 of Montclar and Nemaguard peach seedlings were similar during the 21 days of the experiment. Four strains of A. tumefaciens bv. 1 were used for soil inoculations in biological control experiments on GF677 and Adafuel peach x almond rootstocks; two were sensitive and two were resistant to agrocin 84. Both strains K84 and K1026 were very efficient in controlling the sensitive strains, but some tumors appeared with both treatments. In the biocontrol of resistant strains, no galls were observed in K1026-treated plants, but some K84-treated plants had galls. Recovery of agrobacteria from galls in experiments with sensitive and resistant strains showed that all of the isolates from the controls or K1026-treated plants and most of the isolates from K84-treated plants had the same characteristics as the inoculated strains. Nine isolates from the K84-treated plants growing in soil inoculated with one resistant strain were virulent and produced agrocin 84. These isolates had a plasmid that hybridized with a probe prepared with the BamHI C fragment from pAgK84. These results show the efficiency of K1026 in biocontrol of agrocin 84-sensitive and -resistant strains of A. tumefaciens and suggest the use of K1026 as a safer organism than K84 for biological control of crown gall.

Abstract
Tracheobronchial ruptures represent a serious pathology difficult to diagnose at the first examination. The authors review 6 cases: four as acute types with pneumomediastinum, pneumothorax and subcutaneous emphysema with a delay in diagnosis of 3.25 days, meanwhile 2 cases were chronic forms with a delay in diagnosis of 124.5 days. Diagnosis should be performed as soon as possible based in the presence of uni or bilateral pneumothorax with pneumomediastinum being confirmed by fiber bronchoscopy. The treatment is based in the resection of the fractured fragments, followed by bronchoplasty always with reabsorbable sutures the most frequent surgical technique, meanwhile in the atelectatic forms it is not possible to perform sometimes and we must practise lung resections.

Abstract
The case of a 70-year-old male with lymphoblastic leukemia is reviewed, who presented the rare and almost always fatal complication of pulmonary mucormycosis, but who was treated satisfactorily with amphotericin B and surgery. The risk of massive hemoptysis in the course of mucormycosis that invades the lung vessels, makes us believe that surgery is an essential part of the management of this disease. It is suggested that the patient be operated as soon as the diagnosis is obtained, as we did in our case, to avoid other risks in combined management with amphotericin B.

We report a very unusual case of a patient with recurrent massive PEs eight years after mediastinal radiotherapy for HD, in which evidence of lymphomatous recurrence could not be demonstrated. The diagnosis of PE as a complication of radiation is presumptive, and other disorders causing PE must be excluded. This condition requires symptomatic treatment and a close follow-up of the patient.

Abstract
The authors' experience with splenic hydatidosis is presented. Sixteen cases, representing 3% of the hydatidosis treated surgically in our center, are reviewed. Pain in the left upper quadrant, splenomegaly and calcifications detected by simple abdominal radiology are the most suggestive indications. The definitive diagnosis is based on abdominal echography and CT scan, which have the greatest sensitivity and specificity. The treatment should be surgical, attempting to preserve as much splenic tissue as possible, although in our experience, it is infrequent that conservative treatment can be used due to massive involvement of the spleen.
