Problems solved by technology

The stability of the lentinan extract prepared by the existing technology cannot meet the requirements of long-term storage of skin care products and high stability in high and low temperature environments, and it is prone to precipitation, turbidity and discoloration
At the same time, the lentinan extract has a special smell. If it is directly applied in skin care products, some consumers may not like the smell, which will affect the quality of the product.

Abstract

The use of lentinan extract in the preparation of skin care preparations with anti-smog effects, wherein the lentinan extract is obtained by water extraction, and the raw materials are pretreated before extraction. Dry at ℃, pulverize, pass through a sieve with an aperture of 0.5 to 1.5 mm, and then process under high temperature and high pressure for 0.5 to 2 hours in an 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 present invention relates to a new application of the lentinan extract prepared by the present invention, specifically a new application of the lentinan extract in preparing anti-smog skin care products, and a skin care composition containing the lentinan extract and its preparation method. Background technique [0002] Edible fungi, such as shiitake mushrooms, straw mushrooms, Tricholoma edodes, boletus and tea tree mushroom, have known skin care effects such as anti-oxidation, moisturizing and anti-aging effects. Tea tree mushroom is known to have antibacterial effects. [0003] 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. [0004] Lentinan is extracted from the fruiting bodies of Lentinus edodes. It is a gluc...
