Title: METHOD FOR SEPARATING AND PURIFYING MOGROSIDE V BY MEANS OF SUBCRITICAL HYDROLYTIC ADSORPTION TECHNOLOGY
Abstract:
Disclosed is a method for separating and purifying mogroside V by means of subcritical hydrolytic adsorption technology. The method desorbs a macroporous adsorption resin enriched with mogroside V under subcritical conditions for water, with water as a solvent, to obtain an aqueous solution rich in mogroside V. The method not only increases the content of mogroside V in a product, but also effectively removes bitter-tasting impurities and residual pesticides, greatly improves the taste adaptability of the product, and increases the safety and quality of the product. The method reduces the number of process steps and reduces the use of organic solvents in the prior art, thereby reducing the overall production cost.
