Abstract:

In order to explore the effects of feeding biological bait (control group J-A) and artificial compound feed (experimental group J-B) on volatile flavor compounds in muscle of Quasipaa spinosa,the volatile flavor compounds in the muscle of Quasipaa spinosa reared on two feeds were detected by gas chromatography-ion mobility spectroscopy, and the fingerprints were compared and analyzed. The volatile flavor substances in the two groups of muscles were detected in 45 peaks with 30 substances, including aldehydes, ketones, alcohols and other substances, and there were 15 aldehydes, 8 ketones, 3 alcohols, 1 acid, 1 furan, 1 puzzle and 1 unknown substance. The relative contents of volatile substances in J-A and J-B were as follows: aldehydes (50.45%, 43.13%), alcohols (18.72%, 5.08%), ketones (28.40%, 49.56%), acids (0.65%, 0.84%), ethers (0.14%, 0.27%), furans (1.31%, 0.29%) and unknown substances (0.30%, 0.72%). Among the main volatile flavor substances, the relative content of aldehydes and alcohols J-A was greater than that of J-B, and the relative content of ketones was less than that of J-B. Feeding artificial compound feed can significantly reduce the volatile odor substances such as hexanal, nonanal and heptanal in the muscle of Quasipaa spinosa, improve the muscle quality of Quasipaa spinose. The results of this study provide a certain reference for the evaluation of muscle quality of Quasipaa spinosa and the identification of products.
