  • Patent number: 11464250
    Abstract: Disclosed is a natural compound sweetener, comprising mogroside V, rebaudioside A, natural tea theanine and dietary fibre. The method for preparing the sweetener comprises the steps of: (1) dissolution, filtration, concentration and sterilization: dissolving the mogroside V, rebaudioside A, natural tea theanine and dietary fibre in water, filtering, concentrating in a vacuum, and sterilizing to obtain a sterilized solution; and (2) paste-collection, drying and granulation: carrying out paste-collection on the sterilized solution obtained in the step (1), vacuum drying the collected liquid paste, and drying and then granulating the dry powder to obtain the sweetener.

  • Patent number: 10743573
    Abstract: 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, decolorization, 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.
