Analysis of the cause of bagged Mochi inflating

Objective To analyze the cause of bagged Mochi inflating. Methods The gas in the bag of the inflated Mochi was analyzed.The microorganisms from the inflated Mochi and its raw material-glutinous rice flour were isolated and identified. Results The content of carbon dioxide in the bag of the inflated Mochi significantly increased to about 50%,and the inflated Mochi and its raw material-glutinous rice flour were mainly contaminated by Candida krusei, Schizosaccharomyces octosporus and Rhodotorula aurantiaca. Con- clusion Transformation of glucose into carbon dioxide by yeast from the raw material-glutinous rice flour caused the inflating of Mochi.
