Study on Nutrient Quality of Farmed Chinese Yellow Sand Soft-Shelled Turtle in Guang Xi

In order to establish a evaluation method of edible quality and nutrient value for Chinese yellow sand soft-Shelled turtle.The nutrition composition in muscle and calipash from three kinds of turtles were determined under different weight gradient.The results showed under the same weight gradient,the content of protein in muscle of farmed Chinese yellow sand soft-Shelled turtle was higher than it in Chinese soft-shelled turtle and wild turtle.The content of fat in muscle of wild turtle was lowest.The content of collagen in calipash of farmed turtle was highest.The collagen in calipash of three kinds of turtles was low molecular weight and belong to type I collagen.The types of vitamin in thigh muscle of farmed turtle was must,its in liver was second,its in calipash was least.The farmed Chinese yellow sand soft-Shelled turtle of Guangxi has rich nutrition and high edible value.
