Nutritional composition and meat tenderness of Rana boulengeri is stated in this eassy, and the comparative analysis among Rana boulengeri, Rana catesbeiana, Rana nigromaculata and Pelodiscus sinensis is also performed.

Study on correlation between single nucleotide polymorphism of CAPN1 gene and muscle tenderness and carcass traits in chicken;

The meat tenderness degree,intramuscular fat content and water content of Jianbai Xiang-pig were measured and (analysed).

Meanwhile, their meat tenderness degree, fat content in intramuscular, water content, pH_1value, water loss rate and the cooked meat percentage are not quite different(P>0.

Correlation between calpastatin and meat tenderness;

This paper introduceed the factors of influencing meat tenderness firstly, then summarized molecular structure and active regulation and physiological function of every part of this system, especially its function to meat tenderizing effect ,and gave a prospect to improve meat tenderness by studying this system.

Beef tenderness is influenced by the internal factors (myofibrillar components, intramuscular connective tissue, and intramuscular fat), which is, in turn, affected by many external factors by different ways.

The LD parameters were then used to establish multi-linear regression(MLR) models to predict the beef tenderness respectively.

Genetic factors affecting pork tenderness;
