Special Issue Information

Dear Colleagues,

Meat products play essential roles in the human diet. Microorganisms often play important roles in the quality of them. The beneficial microbes present in fermented meat products include bacteria, molds, and yeast, which can promote the formation of special flavors, characteristic colors, and desired textures of the products, inhibit the growth of harmful microorganisms, reduce the production of harmful substances, and endow the meat products with functional ingredients. Over the past few decades, bioprotective cultures have also been developed for the protection of meat and meat products during storage. Harmful microorganisms, including spoilage and pathogenic bacteria, however, are of great concern for the meat industry due to their influence on the quality and safety of the products. It is urgent to develop efficient methods to control them and thus prolong the shelf-life of the products and enchance food safety.

Potential topics include, but are not limited to, the following:

  1. Microbial ecology and its relationship with quality of meat products;
  2. Exploration of beneficial microorganisms derived from meat;
  3. Bioprotective cultures and bioprotection for meat products;
  4. Detection, isolation, and identification of spoilage and pathogenic bacteria in meat;
  5. Control of harmful microorganisms in meat.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

Xiangxi Yellow Cattle, an indigenous Chinese livestock breed recognized for its exceptional nutrient composition and superior meat characteristics, has gained significant market preference among consumers. This investigation focused on evaluating physicochemical attributes, flavor development patterns, and bacterial population dynamics in chilled beef samples stored at 4 °C over an 8-day period. The research further examined interrelationships between meat parameters, predominant microbial species, and crucial aroma-active substances. Findings revealed a progressive elevation in lipid/protein oxidation levels, biogenic amine accumulation, and TVB-N values as microbial proliferation intensified toward the late storage phase. Microbial analysis demonstrated a final total viable count of 7.17 log10 (CFU/g), with bacterial community dominance distributed among Firmicutes (58.15%), Proteobacteria (29.56%), and Bacteroidota (12.05%). Notably, Brochothrix thermosphacta emerged as the primary spoilage organism in terminal storage phases. Volatile organic compounds (VOCs) in the beef during storage were analyzed, with a total of 66 compounds identified. The critical analysis identified 2,3-butanedione and 2-butanone as microbial metabolism-dependent substances showing strong correlations with meat quality parameters, emerging as freshness markers for beef evaluation. Importantly, the study highlighted the necessity for deeper investigation into microbial–VOC interactions, particularly considering the intricate bacterial ecosystems in aquatic environments. These outcomes enhance our understanding of spoilage mechanisms in Xiangxi Yellow Cattle beef while proposing practical approaches for microbial control in meat preservation systems. Full article

This study aimed to investigate the protective effects of inoculating Lactobacillus plantarum R2 and Lactobacillus sakei B2 on low-salt sliced chicken sausages during storage at 5 °C. The results demonstrated that L. plantarum R2 inhibited the growth of Pseudomonas fluorescens (p < 0.05). The results of the high-throughput sequencing indicated that the chicken sausage inoculated with L. plantarum R2 improved the microbiological quality of the sample. The levels of thiobarbituric acid reactive substances and carbonyl content of the sausages treated with L. plantarum R2 and L. sakei B2 were lower than those of the control (p < 0.05). L. plantarum R2 exhibited a higher antioxidant activity compared to that of L. sakei B2. Therefore, L. plantarum R2 was found to have the potential to improve physicochemical properties, organoleptic characteristics, and food safety of low-salt sliced cooked chicken sausages.
