Problems solved by technology

[0004] However, the Ganoderma lucidum polysaccharides obtained by water extraction and alcohol precipitation generally have the reddish brown color of Ganoderma lucidum itself. When directly added to the cream, the product will have a darker reddish brown color, poor appearance color, and rough texture.
At present, the decolorization methods of polysaccharide extracts generally adopt activated carbon adsorption method, hydrogen peroxide oxidation method and macroporous resin ads

Example Embodiment

[0017] Example 1:

[0018] After taking 10g Ganoderma lucidum fruit body slices, add 100mL distilled water, 75℃ hot water reflux extraction once, add ethanol to the extract to make the final concentration of ethanol 60%, 4℃ stand for precipitation for 10h, suction filtration, precipitation at 40℃ drying Dried and crushed to obtain Ganoderma lucidum polysaccharide powder.

[0019] Weigh 1g of Ganoderma lucidum polysaccharide powder and dissolve it in 500mL water and mix to make a solution, add 5.01g activated carbon, adjust the pH to 2.5, ultrasonically mix for 20s, and let stand at 20℃ for 20min, 4000r·min -1 Centrifuge for 10 min and take the supernatant to obtain a colorless and transparent Ganoderma lucidum polysaccharide extract. The content of Ganoderma lucidum polysaccharide is determined by phenol sulfuric acid method, and the decolorization rate of Ganoderma lucidum polysaccharide is determined by measuring the OD of the sample before and after decolorization. 490nm Finall...

[0020] Example 2:

[0021] After taking 10g of Ganoderma lucidum fruit body slices, add 500mL distilled water and reflux with hot water at 99°C for 3 times. Add ethanol to the extract to make the final concentration of ethanol 90%. Leave it to settle at 25°C for 24h, filter with suction, and dry the precipitate at 60°C. Dried and crushed to obtain Ganoderma lucidum polysaccharide powder.

[0022] Weigh 2.5g of Ganoderma lucidum polysaccharide powder and dissolve it in 500mL water and mix to make a solution. Add 15.075g of activated carbon, adjust the pH to 4.5, ultrasonically mix for 60s, and let stand at 40℃ for 100min, 10000r·min -1 Centrifuge for 30 minutes, and take the supernatant to obtain a colorless and transparent Ganoderma lucidum polysaccharide extract with a decolorization rate of 99.5% and a polysaccharide retention rate of 66.6%.

Example Embodiment

[0023] Example 3:

[0024] The decolorized Ganoderma lucidum polysaccharide extract 100g, propylene glycol 25g, triethanolamine 0.1g and propylparaben 0.05g were prepared into the water phase, and then 4g mineral oil, 1g lanolin and 2g cetyl alcohol were prepared into the oil phase. . Heat the oil phase and water phase to dissolve separately, keep the temperature at 50℃ and keep the speed at 320r·min -1 , Slowly add the oil phase to the water phase, emulsify for 5 minutes, let stand and cool to room temperature to obtain a hand cream.

Abstract

The invention relates to decolorized ganoderma lucidum polysaccharide extract and a method for preparing hand cream by using the same. The decolorized ganoderma lucidum polysaccharide extract is characterized by being prepared by the following steps: performing refluxing extraction in hot water on ganoderma lucidum fruiting body, precipitating in ethanol, performing suction filtration, drying the precipitate, grinding the precipitate to obtain ganoderma lucidum powder, adding deionized water, uniformly mixing to prepare solution, adding active carbon according to a principle that the mass of the active carbon is 1 to 3 percent based on the total mass of the solution, uniformly mixing by ultrasonic waves, centrifuging at a rotation speed of 4,000 to 10,000r.min<-1>, and collecting supernate to obtain the colorless transparent ganoderma lucidum extract; preparing a water phase by using the extract, propylene glycol, triethanolamine and propylparaben, preparing an oil phase by using mineral oil, lanolin and cetanol, heating the oil phase and water phase respectively till the solutes dissolve, adding the oil phase into the water phase, emulsifying, standing and cooling to prepare the hand cream. When the method is used, the decolorizing rate of the ganoderma lucidum reaches 99.6 percent, the retention rate of the ganoderma lucidum reaches 66.7 percent, and the hand cream prepared by the ganoderma lucidum is pure white, fine and lubricant, has obvious moisturizing effect and gives off natural fragrance of ftillgi.

Description

Technical field [0001] The invention relates to a Ganoderma lucidum polysaccharide extract, in particular to a Ganoderma lucidum polysaccharide extract obtained by decolorizing activated carbon and ultrasonic waves; in addition, it also relates to a method for preparing hand cream by using the Ganoderma polysaccharide extract. Background technique [0002] In modern society, people are not only exposed to various electromagnetic radiation environments for a long time, but also often come into contact with various chemical lotions (detergents, soaps, washing powders, etc.), resulting in skin dehydration or decreased antioxidant capacity. Lack of elasticity, dryness, and roughness. Existing skin care and hand care products are mostly based on chemical ingredients containing heavy metals. Although they can moisturize and whiten the skin, long-term use will cause skin thinning, and accumulation will lead to more serious skin problems. Natural and effective Skin care and hand care pr...
