Special Issue Information

Dear Colleagues,

Throughout today’s meat and food industry, countless efforts are focused on creating consumer products that achieve a multitude of characteristics to attain shopper acceptability and the possibility of repeat purchases. Meat processing remains a necessary tool that converts food animals into consumer-ready products. From steaks and roasts to sausages and deli meats, the processing of meat is vital for consumer usability. What is often overlooked during these processing activities are the changes in wholesomeness and storage durations. Each year, consumers increasingly rely on meat and food products that have been processed and packaged for convenience. This Special Issue is focused on providing a resource for authors to share new knowledge of changes to meat products that occur as a result of processing. Storage duration, food safety, flavor, surface color, texture, cooking methods, and processing aids may be included, but the category of inclusion for meat changes caused by processing or storage is limitless.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study aims to determine the differences in the effects of vacuum packaging and modified atmosphere packaging on the quality, flavor, and microorganisms of Mianning ham. Vacuum packaging exhibits stronger antioxidant properties (a* value), while modified atmosphere packaging inhibits microorganisms and delays the decline of Aw through CO2. A total of 249 volatile substances was determined in the ham, while 19 main flavor substances, such as 1-octanol, hexanal, 2-nonanone, and p-cresol, were identified. It was found that the packaging method significantly affected the contents of alcohols and hydrocarbons. At the phylum level, Firmicutes is the dominant bacterial community. At the genus level, in the vacuum packaging group, Tetragenococcus and Carnobacterium are the core contributing bacteria for flavor, while Staphylococcus is dominant in both packaging types and may inhibit flavor formation.

Yak meat jerky, a traditional high-protein food commonly consumed in high-altitude regions, is often produced via air-drying, which may adversely affect its nutritional quality and digestibility. This study systematically compared the gastrointestinal digestion profiles of air-dried yak meat (ADM) and vacuum freeze-dried yak meat (VFDM) using a dynamic in vitro human stomach–intestine (DHSI-IV) system. Key digestive parameters, including gastric emptying kinetics, particle size distribution, and protein hydrolysis, were evaluated under physiologically relevant conditions. VFDM exhibited superior hydration capacity, contributing to delayed gastric emptying of the mixed solid–liquid phase (t1/2 = 85.1 ± 1.0 min) compared to ADM (t1/2 = 80.4 ± 1.2 min), indicating increased gastric satiety. Conversely, VFDM showed a faster solid-phase gastric emptying (t1/2 = 107.2 ± 0.8 min) relative to ADM (t1/2 = 113.1 ± 2.7 min), likely due to improved texture and rehydration. Both jerky types exhibited progressive particle disintegration; by 180 min, large particles (>2.0 mm) decreased to 16.88% ± 2.63% in ADM and 20.04% ± 0.64% in VFDM (p > 0.05). Protein digestibility, measured by SDS-PAGE and the degree of hydrolysis (DH), was significantly higher in VFDM (38.5 ± 3.6%) than in ADM (34.0 ± 0.1%, p < 0.05), with VFDM demonstrating more rapid and extensive protein degradation across gastric and intestinal phases. These improvements may be attributed to the porous microstructure and reduced processing-induced protein cross-linking in VFDM, facilitating enhanced enzyme access. Overall, vacuum freeze-drying substantially improved yak jerky protein digestibility, offering the potential for the development of meat-based functional foods targeted at individuals with compromised gastrointestinal function.
