Problems solved by technology

[0003] The activity of onion anthocyanins is stronger than the proanthocyanidins found so far, and has a strong ability to scavenge free radicals in the body. However, its extraction rate is not high, and common organic solvent extraction is not safe due to solvent residues. Therefore, it is necessary to provide a A safe and effective preparation method capable of increasing the anthocyanin yield and extraction rate of onions, and applying it to the preparation of sunscreens to improve the diversity and anti-aging capabilities of sunscreen products

Embodiment 1

[0028]This embodiment provides a sunscreen, said sunscreen is composed of the following components by weight: 15 parts of onion anthocyanins, 10 parts of shiitake mushroom extract, 13 parts of wheat bran extract, 14 parts of propolis, 7 parts of walnut powder extract, 15 parts of tea seed oil, 10 parts of isopropyl palmitate.

[0029] ① The extraction method of the shiitake mushroom extract in this example is as follows: fresh shiitake mushrooms are chopped and mixed with methanol with a volume percentage of 10% according to the solid-to-liquid mass ratio of 1:2, and stirred and soaked in a water bath at a temperature of 900°C for 3 time, each 40min, filter, and combine the filtrate to carry out decompression distillation and concentration to remove methanol, and concentrate the concentrated solution to 1 / 5 of the stock solution to obtain the mushroom extract. The total amino acid content in the extract is 132.54mg / g, unsaturated The content of fatty acid was 85.16mg / g, and th...

Embodiment 2

[0048] This embodiment provides a sunscreen, which is composed of the following components by weight: 25 parts of onion anthocyanins, 15 parts of shiitake mushroom extract, 18 parts of wheat bran extract, 19 parts of propolis, 15 parts of walnut powder extract, 25 parts of tea seed oil, 15 parts of isopropyl palmitate.

[0049] The extraction method of the shiitake mushroom extract, the extraction method of the wheat bran extract, and the extraction method of the walnut powder extract in this embodiment are completely consistent with those in Example 1.

[0050] Wherein, the preparation method of onion anthocyanin comprises the following steps:

[0051] (1) Wash the mature onions, remove impurities, and chop them, then mix them with water according to the solid-to-liquid mass ratio of 1:4, put them into a beater to make a slurry, and take the filtrate after filtering to obtain onion juice;

[0052] (2) Carry out enzymatic hydrolysis at a temperature of 40°C with an added enzy...

Embodiment 3

[0066] This embodiment provides a sunscreen, which is composed of the following components by weight: 20 parts of onion anthocyanins, 12 parts of shiitake mushroom extract, 15 parts of wheat bran extract, 17 parts of propolis, 13 parts of walnut powder extract, 20 parts of tea seed oil, 12 parts of isopropyl palmitate.

[0067] The extraction method of the shiitake mushroom extract, the extraction method of the wheat bran extract, and the extraction method of the walnut powder extract in this embodiment are completely consistent with those in Example 1.

[0068] Wherein, the preparation method of onion anthocyanin comprises the following steps:

[0069] (1) Wash the mature onions, remove impurities, and chop them, then mix them with water according to the solid-to-liquid mass ratio of 1:3, put them into a beater and beat them into slurry, filter and take the filtrate to obtain onion juice;

[0070] (2) Carry out enzymatic hydrolysis at a temperature of 37°C according to the a...

Abstract

The invention relates to the technical field of sunscreen processing, in particular to a sunscreen cream and a preparation method thereof. The sunscreen cream is prepared from onion anthocyanin, mushroom extracting solution, wheat bran extracting solution, propolis, walnut powder extractive, tea-seed oil and isopropyl palmitate. The sunscreen cream comprises rich onion anthocyanin, sodium phytate,vitamin, unsaturated fattyacid, butyric acid oxidase, tannin and the like, and these components can effectively eliminate free radicals in a human body, prevent peroxidation of polyunsaturated fattyacids on biological membrane caused by the free radicals, enhance anti-lipid peroxidation of the human body, protect tissues of the human body, effectively reduce membrane system damage; meanwhile, the saturated fatty acid, the tea-seed oil and the like can reflect sunshine, have protective effect on skin, and have effective sunscreen effect.

Description

【Technical field】 [0001] The invention relates to the technical field of sunscreen processing, in particular to a sunscreen and a preparation method thereof. 【Background technique】 [0002] Ultraviolet rays in the sun are the main factors that cause skin aging and the formation of blemishes on the surface of the skin. Ultraviolet rays can lead to melanin precipitation, cell proliferation, telangiectasia, decreased immune function, and the formation of skin cancer. At present, sunscreen is usually applied to the skin outdoors to prevent ultraviolet rays from damaging the skin. The skin is shielded from UV rays, thus preventing skin sunburn. The polyhydroxy structure of anthocyanin makes it have special antioxidant activity and the ability to scavenge free radicals. It is the most powerful free radical scavenger found so far, and has very strong in vivo activity. If anthocyanins can be applied to sunscreen, it will further enhance the activity of sunscreen, improve the circu...
