The present application relates to a technique for extracting mogroside V. Provided is a method for extracting high-purity mogroside V from Siraitia grosvenorii . The specific steps comprise: pre-treatment of a raw material, extraction, centrifugation, enzymolysis, ultrafiltration, nanofiltration, bleaching, concentration, microwave drying, and pulverization. The invention utilizes a membrane-based technique for separation and purification, and only uses pure water as a solvent to eliminate usage of an organic solvent. The method can be easily performed, has a simple process, and provides a safe, environment-friendly, high quality, and low-cost product. The method can be used to realize continuous large-scale industrial production. |
