Special Issue Information

Dear Colleagues,

The meat industry constantly needs to innovate itself to achieve the social, financial and environmental demands, and green processing and preservation of meats and meat products can respond well to these challenges. The goal of this Special Issue is to inspire the innovation of knowledge and technology in the topic of “Trends to Green Processing and Preservation of Meats and Meat Products”. Specifically, this Special Issue includes but is not limited to the following fields: (i) enhancing shelf life and the nutritional quality using naturally derived ingredients; (ii) how the components from natural ingredients affect meat protein functionalities; (iii) preventing the formation of hazardous substances; (iv) eliminating wastes and byproducts; (v) reducing energy use and water use.

The present research work was based on evaluating the effects of Eucommia ulmoides leaf extract (EULE) on the technological quality and protein oxidation of cooked pork sausage during refrigerated storage. Sausages were manufactured with different levels of EULE (0, 0.15, and 0.3 g/kg) and stored at 4 °C for 3, 20, and 40 d, respectively. Quality attributes including cooking loss, texture, and color were evaluated, and the total carbonyl and total sulfhydryl as well as the specific markers α-aminoadipic acid semialdehyde (AAS) and lysinonorleucine (LNL) were analyzed for protein oxidation. The results revealed that the inclusion of EULE exhibited effectiveness in reducing the formation of protein carbonyls, particularly AAS and LNL, while inhibiting the loss of total sulfhydryl. Nevertheless, EULE increased the cooking loss, hardness, and chewiness of the sausages compared to the control group. These findings demonstrated that EULE could be considered a potential natural antioxidant for use in sausage production. Full article

The clean-label movement has markedly increased consumer demand for meat products free from synthetic additives, such as sodium nitrite, ascorbate, and phosphate. This review summarizes strategies to replace these additives with natural alternatives while preserving the functional and quality properties of traditionally cured meats. Nitrite replacement commonly employs nitrate-rich vegetables, alongside nitrate-reducing starter cultures or pre-converted nitrite powders for adequate nitric oxide production and meat pigment stabilization. Ascorbate substitutes include vitamin C-rich materials and polyphenol-based antioxidants from green tea and rosemary, supporting nitrite reduction and contributing to meat pigment and oxidative stability. To compensate for phosphate functions, natural substitutes such as hydrocolloids, dietary fibers, protein isolates, and calcium powders from eggshells or oyster shells have shown partial success in restoring water-holding capacity, pH buffering, and textural integrity. In addition, non-thermal processing technologies, such as high-pressure processing, ultrasound, and cold plasma are explored as complementary strategies to enhance the efficacy of natural ingredients and support industrial scalability. However, challenges persist regarding ingredient variability, dose-dependent effects, and consistency in functional performance. Future research should focus on synergistic ingredient combinations, formulation standardization, and scalable application in industrial production to ensure the production of high-quality clean-label meat products.
