Abstract
The present disclosure relates to a method to improve the encapsulation efficiency and physicochemical stability of ginsenosides Rg3 and CK nano-emulsion, belonging to the field of functional emulsions. The method to improve the encapsulation efficiency and physicochemical stability of ginsenosides Rg3 and CK nano-emulsion, includes the following steps: (1) WPI, Tween 80 and water were mixed evenly according to the amount ratio of 0.5 g:0.5-0.7 g:50 mL to obtain the aqueous phase; (2) Mixing a saponin extract containing the minor ginsenosides Rg3 and CK with edible oil evenly to obtain the oil phase; (3) Mixing the aqueous phase with the oil phase, carrying out shearing dispersion to obtain coarse emulsion, and then allowing the coarse emulsion to be subjected to microfluidization homogenization to obtain an oil-in-water nano-emulsion containing the minor ginsenosides Rg3 and CK. The nano-emulsion of the disclosure has a high encapsulation efficiency of Rg3 and CK, good physicochemical stability during storage, freeze-thaw cycles, heating, and other industrial treatments, which could be used to improve the bioavailability of minor ginsenoside Rg3 and CK.
