Apoptosis serves as the initial phase in the conversion of muscle to meat, driving key biochemical and morphological changes in the postmortem muscle. To effectively improve and control meat quality across different animal species, it is important to gather more information on the mechanisms by which apoptotic potential, mediated through the interaction of apoptosis-related molecules, influences meat quality variations. The apoptotic potential, determined by the balance between apoptotic and anti-apoptotic molecules, such as Ca, cytochrome , caspases, and heat shock proteins, varies among different species. A moderate to rapid apoptotic rate can improve textural properties in species with a higher proportion of type I fibers, such as cattle. In contrast, in species with a predominance of type IIB fibers, such as pork and poultry, rapid apoptosis can lead to undesirable quality traits. Therefore, understanding these species-specific apoptotic responses is critical for improving and maintaining meat quality across various species.

Changes in basic composition and digestive characteristics of pork induced by frozen storage.

Introduction: Frozen pork can reduce the quality of the meat and alter the digestibility and bioavailability of meat proteins in the human body. In this study, we investigated the changes in the basic composition during frozen storage and their effects on the structural properties of digestion products after protein digestion.
Methods: The impacts of frozen storage at different temperatures (-8, -18, -25, and -40°C) and for different times (1, 3, 6, 9, and 12 months) on the basic components and digestive characteristics of pork were evaluated.

Background: Meat is a good source of protein in the human diet, and more than three-quarters of the world's population consumes it. It is the most perishable food item since it has enough nutrients to enable microbial growth. In underdeveloped nations, animals are routinely slaughtered and sold in unsanitary conditions, compromising the bacteriological quality and safety of the meat received from the animals.

Introduction: Non-typhoidal (NTS) are leading bacterial agents of foodborne illnesses and a global concern for human health. While there are over 2,600 different serovars of NTS, epidemiological data suggests that certain serovars are better at causing disease than others, resulting in the majority of reported human illnesses in the United States. To improve food safety, there is a need to rapidly detect these more pathogenic serovars to facilitate their removal from the food supply.

This study aimed to evaluate the effects of dietary inulin (0-30 g/kg) on duck meat, muscle fiber types, meat quality, antioxidant ability, Low-field nuclear magnetic resonance, amino acid and off-flavor. These results indicated that inulin promoted the conversion of type II to type I muscle fibers. Compared with the control group, supplementation with 20 g/kg inulin reduced ( < 0.
