Problems solved by technology

[0005] The first method of the above two extraction methods is to extract at a high temperature of 50°C and the second method is to boil at a high temperature before extraction. The starch in barley swells and splits at a high temperature to form a uniform paste solution. Gelatinization, which will increase the antiseptic properties of the barley extract, which will have a bad effect on the use of the barley extract in cosmetics
Moreover, high-temperature extraction and high-temperature boiling will also cause excessive sugar content, and the sugar content in the permeate and retentate will increase in the same proportion, resulting in a very strong sticky feeling in cosmetics such as essences, which will greatly increase consumer acceptance. reduce

Embodiment 1～7

[0028] A preparation method of barley hydrolyzate, comprising the steps of:

[0029] In step (1), the seed of Job's tears is pulverized, and the mesh particle size after pulverization is A mesh;

[0030] In step (2), add purified water (ratio of solid to liquid is H), add B enzyme to hydrolyze at a temperature of C degrees Celsius, and the hydrolysis time is D hours;

[0031] Step (3), centrifugal separation, taking the liquid part;

[0032] Step (4), high temperature goes out enzyme, makes enzyme inactivation precipitation, and temperature is about E degree Celsius, and the time is about F minute;

[0033] In step (5), membrane filtration is used to obtain permeate and retentate, and the retentate is dried to obtain barley hydrolyzate, wherein the pore size of membrane filtration is about G μm.

[0034] See Table 1 for the values ​​of the above parameters.

[0035] Table 1

Embodiment 8

[0038] Embodiment 8: to tyrosinase activity inhibition experiment

[0039] Reagents: tyrosinase, tyrosine, sodium dihydrogen phosphate, disodium hydrogen phosphate, positive control (arbutin, nicotinamide), sample, deionized water.

[0040] Specific operation: as shown in Table 2, sequentially add phosphate buffer solution, sample solution, and tyrosine solution into the test tube, and place in a water bath at 35° C. for 10 minutes. Then, add tyrosinase solution, mix well, and incubate at 35°C for 30 minutes, transfer to a cuvette quickly, and measure the absorbance at 475nm.

[0041] Table 2

[0042]

[0043] The absorbance value of the test group is A1, the absorbance value of the negative control group is A2, the absorbance value of the positive control group is A3, and the inhibition rate=1-[(A1-A2) / (A3-A2)]*100%.

[0044] Please see Table 3 for the results of the tyrosine inhibition test.

Abstract

The invention discloses a preparation method of barley hydrolyzate, comprising the following steps: step (1), pulverizing barley; step (2), adding purified water and enzyme low-temperature hydrolysis; step (3), centrifugal separation, and taking the liquid part Step (4), high temperature inactivation of enzymes, enzyme inactivation and precipitation; Step (5), membrane filtration to obtain permeate and retentate, and retentate drying to obtain barley hydrolyzate. The invention also discloses the barley hydrolyzate prepared by the above preparation method and the application of the barley hydrolyzate in cosmetics. The barley hydrolyzate of the present invention adopts low temperature hydrolysis, does not do high-temperature boiling before hydrolysis, reduces the gelatinization of the starch in the barley as much as possible, reduces the antiseptic performance of the barley water, and effectively controls the sugar content in the barley water; adopt the barley of the present invention The barley hydrolyzate obtained by the preparation method of the hydrolyzate significantly enhances the inhibitory effect on tyrosinase; the skin feeling of the barley hydrolyzate of the present invention is significantly improved, and can replace a high proportion or all of water in cosmetics.

Description

technical field [0001] The invention belongs to the technical field of separation of natural products, and in particular relates to a barley hydrolyzate, its preparation method and its application in cosmetics. Background technique [0002] Barley (Coix chinensis Tod.), also known as coix seed, coix seed rice, medicinal corn, six millet, etc., is the mature seed of coix coix, which is cool in nature, sweet and light in taste, enters the spleen, lung and kidney channels, and has The effect of benefiting water, invigorating the spleen, eliminating disadvantages, clearing away heat and discharging pus. Barley is planted in most parts of our country, mainly in Fujian, Liaoning, Hebei, Guangdong, Hainan and other places. Barley not only has comprehensive nutritional components, including 16% to 21% of protein, 4% to 6% of fat, and 79.2% of carbohydrates, but also contains 18 kinds of amino acids, multivitamins and minerals needed by the human body, ranking first among grasses. ...
