ANALYSIS ON NUTRIENT COMPOSITIONS IN THE MUSCLES OF FOUR STRAINS OF PELODISCUS SINENSIS
摘要
Abstract
Ink turtle is one stain of P. sinensis in south Anhui province, which is very popular in local market. In this study, the differences of basic nutrient compositions, including amino acid and fatty acid contents in the muscles, and collagen contents in the calipash of four strains of P. sinensis were compared, which are ink turtle, wild turtle, Huai River turtle, and T. japonicus. The results showed as follows: (1) the moisture contents in the muscles of four strains were 80.40%, 79.48%, 81.57% and 79.25%, respectively. The moisture contents in ink turtles and Huai River turtles were significantly higher than those in the wild turtle and T. japonicas (P＜0.05). The crude protein contents in the four strains were 17.82%, 17.60%, 15.93% and 16.40%, respectively. The crude protein content in ink turtle was the highest, which was significantly higher than that in the Huai River turtle and T. japonicus (P＜0.05). The crude fat contents were 0.42%, 1.43%, 0.65% and 1.06%, respectively. The crude fat content in ink turtles was significantly lower than that in other strains (P＜0.05), while the ash showed no significant difference among each other (P＞0.05). (2) The ink turtle had the highest contents of TAA and DAA in muscles. (3) The UFA in the four strains of P. sinensis was 65.19%, 56.44%, 59.20% and 54.73%, respectively, which was significantly higher in the ink turtle than in other strains (P＜0.05). The content of MUFA in ink turtle was significantly lower than in wild turtle, while the content of PUFA in ink turtle was significantly higher than in other strains (P＜0.05). The contents of SFA in the four strains of P. sinensis were 35.20%, 41.85%, 39.41% and 39.98%, respectively, which was significantly lower in ink turtle than that in other strains (P＜0.05). (4) The contents of DHA and EPA in ink turtle were significantly higher than those in the Huai River turtle and T. japonicus , which had no significant difference with those in wild turtle. AA in muscles of ink turtle was signi-ficantly higher than that in other stains (P＜0.05). (5) There was no obvious difference in the collagen content at cali-pash among the four strains of P. sinensis (P＞0.05). Therefore, the ink turtle is an indigenous strain with high nutritive value and delicious flavor.关键词
