Embodiment 1
[0048] The preparation of embodiment 1 coix seed fermented liquid
[0049] According to the preparation method recorded in the priority application 201711165203.6, the coix seed fermented liquid with high γ-aminobutyric acid content was prepared:
[0050] Step 1, weigh 15-25g of skimmed milk powder and add it to 100-250mL of warm boiled water, stir and disperse evenly, after the temperature cools below 40°C, add 0.5-1.0g of yogurt fermented bacteria powder (containing Streptococcus thermophilus, Bulgarian milk Bacillus, purchased from Beijing Chuanxiu Technology Co., Ltd.), stirred and dispersed evenly, cultured and fermented in a sealed manner until curdled milk was formed and the yogurt flavor was emitted, and the coix seed starter was made;
[0051] Step 2, wash the coix seed with water and dry it, then crush it through a 20-100 mesh sieve; weigh 150-200g coix seed powder and add it to 1.0L deionized water, stir to disperse, add liquefaction enzyme (purchased from Angel Yea...
Embodiment 2
[0053] The preparation of embodiment 2 whitening freeze-dried powder
[0054] In this example, a whitening freeze-dried powder containing coix seed fermented liquid, blue copper peptide and collagen was prepared.
[0055] The preparation method is as follows:
[0056] Take 0.03 g of blue copper peptide (purchased from Jitai Biotechnology Co., Ltd., production batch number 20170620), and then add 1.0 g of coix seed fermented liquid prepared in Example 1 and 0.015 g of macromolecular collagen (purchased from Guangzhou Xiangbo Biotechnology Co., Ltd., Molecular weight 100,000-300,000 Daltons), add water to make up to 3.0g, mix well, put in vials, freeze-dry at low temperature, and make whitening freeze-dried powder.
Embodiment 3
[0057] Example 3 Whitening ability test of whitening freeze-dried powder
[0058] Referring to the methods in the literature (Yan Hang, Tang Ting, Gui Hui, etc. The inhibitory effect of coicis extract on tyrosinase. Chinese patent medicine, 2013, 35(4): 696-699), through the detection of whitening freeze-dried powder (this Invention Example 2 preparation) on the inhibition of mushroom tyrosinase activity in vitro, according to the degree of solution fading and enzyme inhibition stoichiometry, quantitative analysis was carried out by spectrophotometry.
[0059] Method: Mix 0.5 mL of 30 mg / mL whitening lyophilized powder aqueous solution and 30 mg / mL arbutin aqueous solution (as a positive control) with 200 U mushroom tyrosinase, make up to 2.5 mL with PBS buffer, 37 Incubate at °C for 10 min, add 0.5 mL of L-tyrosine (purchased from Sigma), incubate at 37 °C for 15 min, and immediately detect the absorbance at 475 nm. In the experiment, the negative control was replaced with P...
