  • Publication number: 20220362167
    Abstract: Disclosed are a water-dispersible cannabidiol product and a preparation method therefor. The water-dispersible cannabidiol product comprises a product which can be prepared by means of the following method: adding an organic phase containing cannabidiol into a water phase for emulsification; after an organic solvent in an emulsion has been removed, adding glycosylase for a glycosylation treatment; and conducting drying to prepare the water-dispersible cannabidiol product. The prepared dispersible cannabidiol product can be quickly dispersed and dissolved in an aqueous solution. The product after the glycosylation treatment is a glucoside mixture in which cannabidiol is a parent nucleus structure and in which different sugar chain structures have been introduced to phenolic hydroxyl groups.

  • Patent number: 10759827
    Abstract: The invention relates to a method for separating and purifying mogroside V by subcritical water desorption technology. The macroporous adsorption resin enriched with mogroside V is subjected to desorption under a subcritical condition of water using water as a solvent, to give an aqueous solution rich in mogroside V. The method not only improves the content of mogroside V in product, but also effectively removes bitter impurities and residual pesticides, greatly improves the taste adaptability of the product, and improves the safety and quality of the product. The method reduces the processing steps and reduces the use of organic solvents in the prior art, and reduces total production costs.

  • Publication number: 20200181671
    Abstract: The present invention relates to a method for increasing the content of mogroside V in Siraitia grosvenorii suspended cells. In the method, 10-200 mg/L of a yeast inducer and 50-260 mg/L of methyl jasmonate are respectively added on days 5 to 11 of the culture cycle of Siraitia grosvenorii suspended cells, thereby increasing the synthesis rate and yield of mogroside V, and also reducing the amount of mogroside II secreted. The method is beneficial for the market-oriented and large-scale production and quality control management of mogroside V.
