Background
Stevioside is a natural component extracted from Stevia, which is following the cane sugar and beet sugar as the third natural sugar substitute with development value and health advocates. The appearance of stevioside is white to slightly yellow crystalline powder, has the characteristics of high sweetness and low calorie. Its sweetness is 200 times to 300 times than cane sugar, but calorific value is only 1/ 300 of cane sugar.
Stevioside extraction of traditional process is by flocculation of removing impurity, centrifugal separation, usually adopts iron or aluminum salt inorganic molecular as flocculant with lime as coagulant aid by acid-base neutralization reaction and formation of flocculation precipitation, but the flocculation reaction is slow, stevia sugar Gan in the condition is easy to be broken, at the same time, dosage of flocculant, flocculation and filtration clarification cycle is longer.
Using membrane technology for Stevia extract of impurity removal, separation and concentration, can avoid the drawbacks of the traditional process, also can improve the extraction liquid polysaccharide purity.
