Abstract:		"Due to the large breeding density and the influence of seasonal changes, the quality of oysters declined. Oysters are often fattened with specific microalgae before sale to improve their quality. Here, the purpose of this study was to study the effects of different microalgae diets on the flavor characteristics of Crassostrea gigas (C. gigas) after three weeks of fattening. The result showed that there was a certain correlation between the fatty acid composition of C. gigas and microalgae. The equivalent umami concentration values of C. gigas fed with Chlorella vulgaris and Pavlova viridis (5.34 and 4.91 g/100 g, respectively) were significantly higher than that of the control group. Gas chromatography-ion mobility spectrometry analysis showed 48 volatile organic compounds, and the principal component analysis plot showed an obvious separation between the C. gigas. These results indicated that diets had a significant effect on the flavor components of oysters"
