Abstract

The invention relates to a preparation method of longan extract. The preparation method adopts a pectase and cellulase simultaneous enzymolysis extraction method. The preparation method comprises thefollowing steps: drying fresh longan with hot air of 80 DEG C, removing peels and kernels, obtaining dried longan pulp, adding deionized water, soaking for 12h, wherein a material-to-water ratio is 1:3, and mashing by using a high-speed tissue mashing machine; adding deionized water into a mashed matter, wherein a material-to-water ratio is 1:12, simultaneously enzymolysing by adopting pectase andcellulase, wherein by calculating according to a weight percentage, the consumption of pectase is 0.6 percent, the consumption of cellulase is 0.05 percent, adjusting a pH value to be 3.1, the enzymolysis temperature is 52 DEG C, the enzymolysis time is 160 min, after the enzymolysis is ended, deactivating the enzyme for 30min at 90 DEG C, filtering for 200 meshes, collecting filtrate, concentrating the filtrate into half-flowing pulp, dissolving the pulp into the deionized water according to a volume ratio of 1:10, stirring, uniformly shaking, thus obtaining the longan extract.

Description

technical field [0001] The application date of the present invention is November 30, 2017, the application number is: 201711240432X, and the title is a divisional application of the invention patent application entitled "A Preparation Method of Freeze-dried Powder of a Composition with Acne Removing Effect". The invention belongs to the technical field of preparation of daily skin care products, and in particular relates to a method for preparing freeze-dried powder of a composition with acne-removing effects. Background technique [0002] Acne has another name called acne, and the occurrence of acne is mainly closely related to factors such as excessive sebum secretion, pilosebaceous duct blockage, bacterial infection and inflammatory response. After entering puberty, the level of androgens in the human body, especially delphitonin, increases rapidly, which promotes the development of sebaceous glands and produces a large amount of sebum. At the same time, abnormal keratin...
