Abstract
The disclosure discloses a Pickering emulsion stabilized by cellulose from ginkgo seed shells and a preparation method thereof, and belongs to the fields of preparation methods of biomass materials and food chemical industry. The disclosure uses ginkgo seed shells as a raw material to obtain high-purity cellulose through hot alkali treatment and sodium chlorite bleaching. After the cellulose is dried, the cellulose is hydrolyzed with sulfuric acid to obtain a cellulose nanocrystal suspension. The suspension is mixed with an oil phase, and the Pickering emulsion is obtained through high-speed shearing and homogeneous emulsification. The disclosure can prepare cellulose nanocrystals with different aspect ratios by adjusting the parameters of high-speed shearing and homogeneous emulsification according to actual production needs. Cellulose nanocrystals with high aspect ratio can be used to prepare stable Pickering emulsions with high oil phase and high viscosity, which can be applied to the fields of food, cosmetics and the like; and cellulose nanocrystals with low aspect ratio can be used to prepare Pickering emulsions with low viscosity and high fluidity, which can to be applied to …
