Study on deodorization technology of cultured large yellow croaker
摘要
Abstract
In order to provide a scientific basis for the deodorization of cultured large yellow croaker ( Pseudosciaena crocea) , the deodorization technology of cultured large yellow croaker was investigated .The existing deodorization technology has been optimized through fuzzy comprehensive evaluation method and the volatile compounds of the raw and the deodorized large yellow croaker have been investigated through gas chromatography-mass spectrometry .The results show that the optimum deodorization method is to use 2 %-concentration ginger juice , with the reaction time being 1 h and the material-to-liquid ratio 1:2.After deodorization , the total number of volatile compounds in the large yellow croaker has reduced from 58 to 45 , with the key fishy odor compounds such as hexanal and ( E, Z)-2,4-heptadienal decreased while the ginger-typical odor compounds being added , such as Comphene, (5R)-2-methyl-5-[(2S)-6-methylhept-5-en-2-yl] cyclohexa-1,3-diene, Α-phellandrene and 1,3,6,10-dodecatetraene, 3,7,11-trimethyl-, (Z,E)-.These suggest that the ginger juice deodorization technique could remove the volatile compounds which contribute to the fishy smell of cultured large yellow croaker .关键词
