Skin care product additive with anti-smog effect and industrialized preparation method thereof

Abstract

The invention discloses an industrialized preparation method of a skin care product additive with anti-smog effect. Wherein, the skin care product additive is lentinan extract, and the raw material of the lentinan extract is pretreated before preparation, and the pretreatment steps are: dry the dried shiitake mushrooms at 50-70°C, crush them, and pass through 0.5-1.5mm After the aperture screen, it is treated under high temperature and high pressure for 0.5-2 hours in anhydrous state. Experiments have proved that the lentinan prepared by the invention can effectively prevent and repair the damage to the skin caused by benzopyrene in the smog. At the same time, the lentinan prepared by the invention can effectively block the absorption of benzopyrene by skin cells.

Description

technical field [0001] The invention relates to an additive for skin care products, in particular to an additive for skin care products with anti-smog effect and a preparation method thereof. Background technique [0002] Lentinus edodes, also known as flower mushroom, shiitake mushroom, and winter mushroom, belongs to Basidiomycota, Agaricaceae, Agaricaceae, Agaricaceae, and Lentinus genus. It is the second largest edible fungus in the world and is known as "mountain treasure" among the people. say. [0003] Lentinan is extracted from the fruiting bodies of Lentinus edodes. It is a glucan with β-D (1→3) glucan residues as the main chain and side chains with (1→6) glucan residues. Lentinan can improve the immune response of the tumor-bearing or infected body. Its preparation has no direct anti-cancer effect in the animal screening test, but it can obviously promote the transformation of lymphocyte culture in vitro. At present, animal experiments have shown that subcutaneo...

Problems solved by technology

Those skilled in the art propose to use sterilized pots to extract lentinan under high temperature and high pressure. Difficulty in solid-liquid separation, unstable extract properties and other defects

In summary, due to the problems in the preparation of the above-mentioned lentinan extracts, there are limitations in the application and large-scale production of the lentinan extracts. How to find a method for preparing lentinan suitable for industrialized large-scale production is a research hotspot for those skilled in the art

[0005] In addition, there is still an important problem in the direct application of lentinan prepared by the prior art in the field of skin care cosmetics, that is, the stability cannot meet the high stability requirements of long-term storage of skin care products and in high and low temperature environments. Adding lentinan extract into Cosmetics are prone to precipitation, turbidity, discoloration, and peculiar smell. Since cosmetics have higher product property requirements than food, the application of lentinan in cosmetics is limited.

The conductivity of lentinan extract will also increase with the increase of the concentration ratio. Adding it to skin care products will affect the product quality and application range. For example, high conductivity solutions are not suitable for adding to emulsions. The extraction rate is usually treated with anion and cation resin desalination method before concentration to reduce the conductivity of the solution. This method has an excellent effect of reducing the conductivity, but the extraction solution of this method will go through acidic and alkaline processes, which will affect the lentinan molecules. With certain damage, the resin will also adsorb some polysaccharide molecules, resulting in a large loss rate of lentinan (loss rate is above 30%), and the yield of lentinan is too low after scale-up production, and the production cost rises

Lentinan extract also has the problem of a special smell, if it is simply applied in skin care products, some consumers may not like the taste
