Special Issue Information

Dear colleagues,

The global demand for protein is expected to double by the year 2050, due to the rapid growth of the world’s population and urbanization. There is currently a paradigmatic shift in the food industry toward the improved utilization of existing protein sources, along with the development of sustainable food production. Despite recent and promising advances in alternative protein sources, animal protein still holds a key role in the supply of this essential nutrient. From the sustainability as well as the protein quality points of view, it makes sense to explore the already available sources of high-quality protein; for instance, co-products from fresh meat and processed meat, which are not utilized to their fullest potential. In this regard, a trend towards recovering proteins from these low-added-value co-products, aiming to meet the needs of the global population, industry profit, and planet sustainability, is on the rise. It is thus urgent to edit a Special Issue on this area, serving as a platform to disseminate the most recent progress and fill the knowledge gap. This Special Issue will focus on the recovery and valorization of proteins or protein hydrolyzates from meat and its co-products for advanced applications as food ingredients, nutritional co-products, bioactive compounds, pet food and animal feed, bioplastics, etc.

We investigated the mechanical, biochemical, and histological properties of hog and sheep casings produced in different countries to elucidate the responsible factors for the toughness quality of natural casings. The toughness and collagen characteristics of sheep and lamb casings were also investigated to elucidate the effect of animal slaughter age on the relationships between connective tissue and the mechanical properties of natural casings. The results showed that the main component of hog and sheep casings was collagen with many layers of sheets. The contents of collagen, elastin, and proteoglycan in hog and sheep casings were similar. The toughest Chinese casings (p < 0.01) possessed a significantly lower heat solubility of collagen (p < 0.01), and a different size and arrangement of collagen fibers. Sheep casings were significantly tougher than lamb casings (p < 0.01). Compared with lamb casings, sheep casings had a significantly low heat-labile collagen content, a low heat solubility of collagen, a large size of collagen fibers, and a high pyridinoline concentration (p < 0.01). Therefore, the high thermal and structural stability of collagen in aged animals may contribute to the enhanced mechanical properties of casings. Full article

Effects of different levels (1%, 3% and 5%) of cherry powder on the physiochemical properties and antioxidant activity of Jiangsu-type sausages were investigated at 4 °C for 30 days. The results show that the sensory evaluation values and physicochemical properties of the sausages had no significant differences compared to the control group when cherry powder addition was 1%, and the alcohols, aldehydes and esters were increased after the addition of cherry powder improved the flavor of sausages. However, higher concentration of cherry powder (3% and 5%) exerted adverse influences on sensory evaluation values and physicochemical properties of sausages compared with the control. The addition of cherry powder could better inhibit lipid and protein oxidation of sausages, and the cherry powder concentration has a positive correlation with its effect on the inhibition of lipid and protein oxidation. In addition, cherry powder could effectively control TVB-N values of sausages during chilled storage. All these results indicate that 1% cherry powder could not only guarantee the physicochemical properties of sausages, but also inhibited the oxidation of sausages during chilled storage. Full article
