Comparative analysis of amino acids and Maillard reaction products of normal Pinctada martensii and Pinctada martensii with black shell disease.

TL;DRAbstract

Amino acids and Maillard reaction products of normal Pinctada martensii and Pinctada martensii with black shell disease were analyzed and compared.Results showed that black shell disease had little effect on amino acids of the flesh of Pinctada martensii,as analysis of variance showed that the one-tailed probability value(P) was 0.93( 0.50).Black shell disease had great influence on Maillard reaction products.19 Kinds of substances were detected from normal Pinctada martensii,most of which were esters,alcohols and alkanes.And 31 kinds of substances were found from Pinctada martensii with black shell disease,most of which were alkanes and alcohols.Small kinds of esters were found in Pinctada martensii with black shell disease,and only two same kinds of substances were found.The relative contents of flavor material were 58.81% of total compounds in normal Pinctada martensii,while those in black shell disease Pinctada martensii were 18.26%.
