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.

Abstract: Luo han guo juice and a preparation method thereof. The method comprises: preparing fresh luo han guo fruits, and washing and grinding the same; adding a macerating enzyme; and performing enzymolysis under an ultra-high pressure of 120-220 MPa and maintaining the pressure for 10-15 minutes.

Abstract: A method for expanding a rectangular section ring to form a non-rectangular section ring. The method includes heating a rectangular section ring of an alloy to a temperature of between 1000 and 1020° C., preheating an expanding block to a temperature of between 260 and 320° C., nesting the inner circumferential surface of the rectangular section ring on the outer circumferential surface of the expanding block; enabling the expanding block to press the inner circumferential surface of the ring in the radial direction, expanding the inner and outer diameter of the rectangular section ring and decreasing the wall thickness thereof for deforming the rectangular section ring to yield a profiled ring billet, whereby finishing a first expanding; rotating the profiled ring billet for 45° along the central axis, whereby finishing a first rotation; and repeating the expanding process and the rotation to obtain a non-rectangular section ring.
