Green alga extract preparation method, green alga extract, anti-aging sunscreen cream containing green alga extract and applying system

Abstract

The invention discloses a green alga extract preparation method, a green alga extract, an anti-aging sunscreen cream containing the green alga extract and an applying system. The green alga extract preparation method includes steps: mixing green algae with citric acid solution, extracting at 40-60 DEG C for 25-45min under ultrasonic frequency of 50-70kHz, filtering, discarding filter residues, anddrying to obtain the green alga extract. According to the preparation method, the citric acid solution is selected for extracting green alga polysaccharides from green algae, cell membrane and cell wall breaking is realized ultrasonically, and accordingly the green alga polysaccharides in cytoplasm of the green algae can be better separated into extract liquid to increase the content of the greenalga polysaccharides in the green alga extract. By extraction of the green alga polysaccharides through selection of citric acid lower than sulfuric acid in acidity, environment damages caused by sulfuric acid can be reduced, so that high environmental friendliness is realized. Low hot water temperature requirements, low consumption, low energy consumption and production cost reduction are realized.

Description

Technical field [0001] The invention relates to the technical field of biochemistry and daily chemistry, in particular to a preparation method of a green algae extract, a green algae extract, an anti-aging sunscreen containing the green algae extract, and an application system. Background technique [0002] Chlorophyta is a member of the Chlorophyta (Chlorophyta) of the plant kingdom, with about 6,700 classifications. It is mainly distributed in fresh water, but also in sea water and wet places on land. Green tide is a harmful ecological phenomenon in which certain large green algae (mainly Ulva green algae) in the seawater explosively proliferate or highly aggregate and cause discoloration of water bodies under specific environmental conditions. It is also regarded as a red tide. Marine disasters. Green tide can cause a variety of hazards and has become a worldwide marine environmental problem. In 2007, the first large-scale green tide of Enteromorpha broke out in the Yellow ...

AI Technical Summary

Problems solved by technology

Chlorella water-soluble polysaccharide has a new and unique structure. Although its related knowledge and application prospects are increasing, chlorophyll polysaccharide is still a resource that has not been fully developed.

[0004] The existing green algae extracts mainly adopt acid extraction method and water extraction method. The acid extraction method needs to use a large volume of organic acid, such as sulfuric acid, and the subsequent treatment process is complicated. Extremely troublesome and harmful to the environment

The water extraction method requires the use of high temperature (80°C-100°C) and large amount of hot water, which consumes a lot of heat energy, and the subsequent concentration process takes a long time

[0005] The current preparation process of green algae extract has the problems of poor environmental protection, high energy consumption and high production cost.
