- Abstract
In this study, the glutinous rice was used to extract starch and protein simultaneously by enzyme assisted colloid mill coupling centrifugation, and the enzymatic soaking process was optimized. The results show that the optimal enzyme assisted process is as follows: mix the coarsely crushed glutinous rice with the distilled water at a ratio of 1:10,then adjust pH value of the mixture to 4.5, and add the pectinase at the mass ratio of 0.8%,and then incubate at 50 ℃ for 60 min for the enzyme hydrolysis. After the pretreated glutinous rice pulp is milled by colloid mill, and after the centrifugation at 6 500 rad/min 4 ℃,the protein extraction rate of the supernatant can reach 43.8% and the starch yield of the filter cake can reach 93.2%.The method can retain the molecular structure of protein and starch to the maximum extent, which can provide a certain reference for the subsequent industrial production.
