Optimize extraction of yam glycoprotein in alkali solution
The study adopts the micro alkaline solution to extract the glycoprotein.Using the methods of single factor test and orthogonal design test of L9(34) ,to study the effects of the extraction time,extraction temperature,the ratio of sample to water,and the solution pH on the extraction rate of the glycoprotein.The experimental results show that the best technological conditions of extracting glycoprotein from yam are that:the extraction temperature is 60 ℃,the extraction time is two hours,the ratio of sample to water is 1:15(g/mL) ,the solution pH is 10,when the highest extracting rate of yam glycoprotein is 0.74%.
