Special Issue Information

Dear Colleagues,

Global meat consumption continues to rise, yet the nutritional richness of meat makes it prone to microbial spoilage and lipid oxidation, leading to significant waste and quality deterioration. Growing consumer demand for natural, minimally processed products further drives the need to replace synthetic preservatives with sustainable alternatives. Novel strategies offer transformative solutions to enhance the sensory and nutritional quality of meat and extend shelf life while meeting clean-label expectations.

Therefore, this Special Issue of Foods, entitled “Novel Strategies to Improve Meat Quality and Shelf Life” invites works (original research papers or reviews) on the current state of knowledge of the subject. Specifically, this Special Issue may include, but is not limited to, the following topics:

(1) Natural bioactive preservatives and their mechanisms (e.g., plant extracts, essential oils, probiotics) for inhibiting oxidation and microbial growth;

(2) Non-thermal processing technologies (ultrasound, pulsed electric field, cold plasma, ultra-high pressure) for quality optimization;

(3) Intelligent and active packaging systems (biopolymer coatings, nanoemulsion delivery, colorimetric indicators, RFID sensors);

(4) Clean-label and functional formulations (low-salt/low-nitrite, byproduct valorization, nutritional enrichment);

(5) Postmortem metabolism regulation and quality formation mechanisms.

Air-dried mutton is a traditional, culturally significant meat product, yet its spontaneous fermentation is inherently constrained by unstable microbial communities, leading to batch-to-batch quality inconsistency and potential food safety hazards. Elucidating whether composite starter cultures can modulate the microbiota and enhance product quality is therefore critical for standardized industrial processing. Herein, we investigated the effects of a defined starter culture (composed of Lactiplantibacillus plantarum and Pediococcus pentosaceus in a 2:1 ratio, with a total inoculum of 108 CFU/g) on the quality and flavor of air-dried mutton, comparing inoculated samples (FJ) with naturally fermented controls (ZR). The fermentation was conducted at 30 °C and 95% relative humidity (RH) for 24 h, followed by air-drying at 4 °C for 21 d, with all assays performed in three biological and three technical replicates. Starter inoculation significantly reduced the pH, water activity (Aw), total volatile basic nitrogen (TVB-N), and thiobarbituric acid reactive substances (TBARS) values while improving sensory acceptability (p < 0.05). Amplicon sequencing analysis revealed a lactic acid bacteria (LAB)-dominated microbiota in FJ samples, with elevated abundances of Pediococcus and Lactobacillus and reduced abundance of Pseudomonas. The inoculated group also exhibited altered eicosapentaenoic acid content and a more diverse volatile flavor profile, with eight key aroma compounds positively correlating with LAB abundance. These findings demonstrate that composite starter inoculation improves physicochemical quality, stabilizes the microbial community, and enhances flavor in air-dried mutton. Further mechanistic validation and scale-up trials are required to confirm industrial applicability. Full article
