Special Issue Information

Dear Colleagues,

The production of meat and meat products plays a fundamental role in global food security, being an important source of high-biological-value protein for the world's population. However, the growing demand for meat in recent decades has raised environmental, social, and economic concerns, driving the search for more sustainable production systems, coupled with low production costs. In recent years, new technological approaches, such as the use of food additives to reduce enteric fermentation, the modulation of the fatty acid profile of meat, the environmental monitoring of production chains, the development of cultivated meats and plant-based alternatives with alternative proteins, and the creation of meat products enriched with natural antioxidants and dietary fibers from agro-industrial waste, have emerged as promising solutions to minimize environmental impacts without compromising production, extending the shelf life of meat products and providing nutrients for the consumer market.

Thus, this Special Issue aims to present innovative strategies for the sustainable production of meat and meat products, addressing aspects such as the application of new technologies, animal welfare improvement, and environmental impact mitigation, with the goal of contributing to a more resilient sector.

In this Special Issue, new research articles, reviews, case studies, reports, and short communications are welcome. We will accept manuscripts from various disciplines related to this topic, including meat science, food science and technology, food safety, and sustainability. Topics of interest for publication include, among others, the following:

  • Factors affecting animal performance and their relationship with carcass yield and meat quality;
  • Use of natural antioxidants in the preparation of meat products;
  • Methodologies applied in the evaluation of meat and meat products;
  • Sustainable animal production and quality of meat and meat products;
  • Nutritional strategies to improve meat and meat product quality;
  • Processing technology, quality control, and sensory evaluation of meat and meat products;
  • Plant-based alternatives for meat products.

We look forward to receiving your contributions.

This study evaluated the effects of enzymatically produced collagen hydrolysate and Salicornia perennans extract on the quality, oxidative stability, and nutritional composition of canned canine meat pâtés. Two formulations were prepared: a control 2% NaCl, no hydrolysate and an experimental sample containing 3% collagen hydrolysate sheep:camel:bovine = 1:1:1, 1% Salicornia perennans extract, and 1% NaCl. Physicochemical, textural, amino-acid, fatty-acid, and oxidative parameters were monitored over 10 days of storage. The treated pâtés showed similar proximate composition moisture 76.1%, protein 9.2%, metabolizable energy (ME) 102 kcal·100 g−1; p > 0.05 but exhibited enhanced functional stability, with reduced water loss syneresis 1.8 vs. 3.1%; p < 0.05 and improved cohesiveness 0.46 vs. 0.41; p < 0.05. Amino-acid enrichment included higher aspartic acid +33%; p < 0.05, methionine +53%; p < 0.05, and tryptophan +39%; p < 0.05, while the lipid profile showed lower SFA 52.8 vs. 56.4%; p < 0.05, higher n-3 PUFA 1.5 vs. 0.8%; p < 0.05, and a reduced n-6:n-3 ratio 3.8 vs. 5.6; p < 0.05. During storage, oxidative markers decreased: TBARS −45%, carbonyls −14%, acid value −18%, and color stability improved by +2.0 pp. These findings confirm the synergistic antioxidant and structuring effects of collagen-derived peptides and Salicornia polyphenols, as evidenced by a 45% reduction in TBARS, 14% lower protein carbonyls, and 18% lower acid value relative to the control (p < 0.05). This synergy enabled a sodium-reduced, clean-label formulation with improved technological performance, oxidative resistance, and shelf-life stability for functional wet dog foods. In addition, it enhanced the color and visual appeal—key attributes that influence both animal palatability and the purchasing decisions of pet owners. Full article

This study investigated the incorporation of Salicornia perennans powder as a natural antioxidant and functional ingredient in cooked sausages, with the aim of improving product quality and promoting sustainable production strategies. The inclusion of 3% Salicornia perennans resulted in a nutritionally favorable shift in the fatty acid profile, with a 1.5-fold increase in α-linolenic acid ALA and the presence of long-chain ω-3 fatty acids EPA and DHA, along with improved PUFA/SFA and ω-6/ω-3 ratios. Lipid and protein oxidation were significantly suppressed during refrigerated storage, as evidenced by the reduced peroxide value of 10.6 vs. 12.8 meq/kg, thiobarbituric acid-reactive substance value of 0.158 vs. 0.210 mg MDA/kg, acid value of 4.6 vs. 5.5 mg KOH/g, and carbonyl compound value of 101.9 vs. 112.3 nmol/mg protein compared to the control. Color stability was enhanced, with ΔE* values remaining below perceptible thresholds in Salicornia perennans-supplemented sausages, highlighting its role in preserving visual quality. Antioxidant capacity was markedly higher, with FRAP values of 14.5 mg GAE/g undetected in the control and improved DPPH radical-scavenging activity of 22.6% vs. 12.5%. These findings demonstrate that Salicornia perennans not only enriches meat products with bioactive compounds and health-promoting lipids but also reduces oxidative spoilage, thereby extending shelf life. The results emphasize the potential of halophyte-based ingredients to support technological innovation, environmental impact reduction, and the development of clean-label functional meat products aligned with sustainable production strategies.
