Abstract: To study the differences in texture properties and nutritional quality of Procambarus clarkia feeding with 5 kinds of feed and non-feeding in rice fields. The texture properties, amino acids, and fatty acids were analyzed by physical property determination, biochemical detection, and chromatographic monitoring. The results demonstrated that in terms of texture, values of hardness, springiness, cohesiveness, adhesiveness, chewiness, and resilience of Procambarus clarkia muscle in group fed by soybean was highest than that in the other groups. In terms of Procambarus clarkia muscle nutritional quality, 17 species of amino acids were determined, and total amino acids (TAA), essential amino acids (EAA) and delicious amino acids (DAA) in non-feeding group were highest than that in the other groups. 39 species of fatty acids were monitored, and total fatty acids (TFA) in non-feeding group were highest than the other groups. Unsaturated fatty acid (UFA) content in group fed by commercial mixed feed B was highest than that in the other groups, and that in non-feeding group was slightly lower than that in group fed by commercial mixed feed B. Furthermore, UFA in non-feeding group and group fed by commercial mixed feed B were higher than that in the other groups. Therefore, certain differences were observed in texture properties and nutritional quality of Procambarus clarkia muscle in different groups. In summary, the taste of Procambarus clarkia muscle in group fed by soybean could be more advantageous than that in the other groups. However, in term of nutritional quality of Procambarus clarkia muscle in non-feeding could be better than that in the other groups.
