Study on nutrients, non-volatile compounds, volatile compounds and antioxidant capacity of oyster mushroom cultivated with corn distillers’ grains

Although corn dried distillers' grains (DDG) can be used as a supplement for oyster mushroom cultivation, there are few relevant researches. In this study, oyster mushroom cultivated with different proportions of DDG and corncob mixes was investigated. Based on the cultivation parameters, nutrients, non-volatile compounds, volatile compounds, and in vitro antioxidant capacity of oyster mushrooms were analyzed and compared. The results suggested that the biological efficiency of oyster mushrooms cultivated with 25% and 50% DDG was increased by 33.05% and 26.93%, respectively, and that the protein content was increased by 6.27% and 8.28%, respectively. LC-MS analysis indicated that gallic acid, caffeic acid, erucic acid, linoleic acid and stearic acid were notably increased (p
