Smoked sausages of bovine meat produced in North Macedonia as a source of pro-technological lactic acid bacteria and coagulase-negative cocci

Smoked bovine sausages, traditional meat products from the Balkan Peninsula, are rich in microbial diversity and represent potential sources of pro-technological microorganisms. This study aimed to characterize these sausages from three different producers collected in green markets of North Macedonia. The analyses included physico-chemical (proximate composition, pH, aw), morpho-textural (color and texture), and microbiological assessments (viable plate counts). Moreover, an isolation campaign was conducted to identify and characterize pro-technological microorganisms. Significant variability was observed in moisture content (ranging from 33.70 to 48.61 %), hardness, and color among samples from different producers. Samples from producer 2 showed the lowest pH (mean ∼4.90) and the highest loads of lactic acid bacteria (up to ∼9 log cfu g-1). Coagulase-negative cocci ranged between 4.84 and 7.47 log cfu g-1. No potential pathogenic bacteria were detected. A total of 30 isolates, primarily Latilactobacillus sakei, Staphylococcus equorum, and Staphylococcus casei, were identified. Isolates of L. sakei S7, S13, and S27 showed strong in-vitro acidification performance, together with the production of exopolysaccharides (EPS), and protease activity. S. equorum isolates S1 and S2 exhibited protease and lipase activities, while isolates S. casei S21 and S28 showed notable lipase and protease activities, along with the production of EPS. Additionally, all S. equorum isolates, except S2, showed nitrate reductase activity, one of the key features able to affect sausage color. These findings highlighted the pro-technological traits of these microbial isolates, suggesting their potential use as starter or adjunct cultures in the meat industry to enhance product quality and safety.

Safety and authenticity risks in heritage food preparation at different types of food service establishments: A case study of Saudi Arabia

In Saudi Arabia, tourism is becoming increasingly popular, and forms an essential element of Vision 2030. Accordingly, food service establishments (FSEs) including hotels, ordinary restaurants, heritage restaurants and productive families (i.e., home-based catering) provide heritage cuisine to tourists. This study aimed to assess the authenticity and safety risks associated with the production of heritage food dishes in different FSEs. An online questionnaire was administered in Saudi Arabia, and a total of 85 culinary professionals from different FSEs responded. The culinary professionals were requested to provide opinions on the frequency of food safety and authenticity risk situations at their FSEs, using a five-point Likert scale. The results indicate that most food safety risk situations occur less frequently in hotels because of strict food safety management systems. In contrast, food safety risk situations are more frequent in ordinary and heritage restaurants, particularly in the absence of personal hygiene requirements. In productive families, most food safety risk situations occur because there are no control systems or inspections. Authenticity risks occur less frequently in productive families and heritage restaurants than in other FSEs. Hotels often/always face authenticity risk situations, such as cooking of heritage dishes by non-Saudi culinary professionals and the use of modern equipment. Ordinary restaurants face the highest risk, mostly because of the limited knowledge and skills of the cooks. Overall, this study provides the first insight into the occurrence of possible safety and authenticity risk situations during the preparation of heritage dishes; this information may contribute to improve the production of safe and authentic heritage dishes in the hospitality industry for tourists and local people.

Food security and the cultural heritage missing link

Though enormous strides have been achieved in recent decades towards reducing food insecurity in the Global South, continued efforts are imperative in light of rapidly expanding populations and threats posed by climate change. A relatively unexplored area in this arena is the nexus between cultural heritage and food security. Cultural heritage embodies indigenous culture, values, and traditions inherited from previous generations. We focus on rice and identify five pathways through which cultural heritage affects food security. Although policy makers face the complex task of balancing trade-offs between preserving cultural heritage and productivity, they can harness cultural heritage to enhance food security by supporting (i) preservation of genetic resources, (ii) valorization, (iii) traditional food processing, (iv) preference matching, and (v) agritourism.

Exploring alternative protein sources: Evidence from patents and articles focusing on food markets

This review considers alternative protein sources through the analysis of food science literature and patents. Data collection was performed from scientific literature and patent documents using the Scopus and National Institute of Industrial Property databases, with a term combination "alternative protein source" and "source* AND protein* AND alternative*". A total of 945 documents were analyzed. The scientific prospection showed that agricultural and biological science was the main application area. The food industry area had the highest number of filed patents. The annual evaluation of published documents demonstrated that this area had been investigated since the 1970s, and the number of articles was twice than that of filled patents. Although protein products are available for sale, animal and vegetable sources replace conventional protein products. Presently, alternative protein sources are already a worldwide trend in the food industry, enabling the development of new products to facilitate their insertion into the consumer market.

Traditional Fermented Beverages of Mexico: A Biocultural Unseen Foodscape

Mexico is one of the main regions of the world where the domestication of numerous edible plant species originated. Its cuisine is considered an Intangible Cultural Heritage of Humanity and ferments are important components but have been poorly studied. Traditional fermented foods are still diverse, but some are endangered, requiring actions to promote their preservation. Our study aimed to (1) systematize information on the diversity and cultural history of traditional Mexican fermented beverages (TMFB), (2) document their spatial distribution, and (3) identify the main research trends and topics needed for their conservation and recovery. We reviewed information and constructed a database with biocultural information about TMFB prepared and consumed in Mexico, and we analyzed the information through network approaches and mapped it. We identified 16 TMFB and 143 plant species involved in their production, species of Cactaceae, Asparagaceae, and Poaceae being the most common substrates. Microbiological research has been directed to the potential biotechnological applications of Lactobacillus, Bacillus, and Saccharomyces. We identified a major gap of research on uncommon beverages and poor attention on the cultural and technological aspects. TMFB are dynamic and heterogenous foodscapes that are valuable biocultural reservoirs. Policies should include their promotion for conservation. The main needs of research and policies are discussed.

Recognising, Safeguarding, and Promoting Food Heritage: Challenges and Prospects for the Future of Sustainable Food Systems

The safeguarding and promotion of food heritage are often considered as a possible way for achieving social and cultural sustainability objectives. This literature review investigates some of the dynamics underlying the heritagisation of food and explores the risks of this process. It focuses mainly on anthropological, geographical, and sociological publications. Overall, it aims to shed light on the strengths and limitations of food heritagisation regarding the improvement of the socio-cultural sustainability of the food system. The analysis highlights cross-cutting risks, namely the omission of tangible and intangible elements of the local food system, and the exclusion of key stakeholders from the recognition and institutionalisation of food heritage. The review highlights the strict interdependence between intangible and tangible elements during food heritagisation, and assesses how local and global interactions can activate and shape this process. It sheds light on the need to pay more attention to the factors, actors, and relationships underpinning the emergence and recognition of food and food-related elements as part of the local heritage.
