Food and Machinery
For finding a rapid and environmental friendly way to extract zymosan (beta-1,3-glucan), a method was established by microwave-assisted heating at low alkaline concentration, which was using the cell wall as a raw material and based on traditional enzyme alkaline. Extraction process was optimized by using response surface method, the optimum process conditions for quadratic regression model analysis were as followed: microwave power 420 W, heating time 5 min; the quantity of enzyme 2 550 U/g. Under this condition, the total sugar value could reach 87.44%, and the verificatio n results was 87.94%.
