Test example 1
The enzyme activities of the whitening enzyme beverages containing the small-molecule peptides and various enzymes in examples 1 to 5 were measured.
Protease activity determination: the specific operation is carried out according to GB/T23527-2009. The definition of the enzyme activity unit is as follows: under the conditions of a certain temperature and a certain pH value, 1mL of crude enzyme solution hydrolyzes casein for 1 minute to generate 1g of tyrosine, namely an enzyme activity unit expressed as (U/mL).
And (3) lipase activity determination: the specific operation is carried out according to the first method (potential method) of GB 23535-2009. The definition of the enzyme activity unit is as follows: 1mL of enzyme solution hydrolyzes a substrate under certain temperature and pH conditions for 1 minute to generate 1mol of titratable fatty acid, namely an enzyme activity unit expressed as (U/mL).
Measuring the SOD enzyme activity: the specific operation is carried out according to the determination of the activity of superoxide dismutase (SOD) in GB 5009.171 health food.

The specific test results are shown in table 1.
TABLE 1 enzyme activity test results table
Test example 2
The alcoholic strength of the whitening ferment beverages containing the small-molecule peptides and various enzymes in examples 1 to 5 was measured and detected with reference to GB/T15038.
The specific test results are shown in table 2.
TABLE 2 alcohol content test results table
As can be seen from tables 1 to 2, in example 2, the self-prepared and separated fermentation bacteria from the fruit and vegetable fermentation liquid are used, so that the alcohol content in the fermentation liquid can be reduced, and the influence on the fermentation quality due to the fact that many mixed bacteria are naturally fermented is avoided, or the dominant fermentation of yeast and lactobacillus is avoided, so that the pH value of the fermentation system is reduced, and the acid-intolerant bacteria stop fermenting or are killed, so that the fermentation quality is influenced. Example 4 selenium is added during the fermentation process to activate the activity of key enzymes in the growth and development process of human body, and at the same time, the metabolic process of zymophyte is accelerated, and the content of metabolites beneficial to human body is increased. Example 5 adding brown sugar during buckwheat fermentation improves the activity of enzymes in the enzyme drink, wherein the activity of lipase is improved most obviously, presumably because the addition of brown sugar increases the osmotic pressure of the fermentation system, which is beneficial to the fermentation.
Test example 3
The whitening efficacy of the whitening enzyme beverages containing the small-molecule peptides and various enzymes in examples 1 to 5 was measured.
An important factor determining the skin color of a human body is melanin, which is produced by pigment cells present in the skin. Melanin produced by melanocytes is transferred to peripheral epidermal cells. The melanocyte-engulfed keratinocytes appear on the skin surface after a certain period of time, thereby largely controlling the skin color.
1. Determination of melanin in human keratinocytes
The subjects of 35-40 years of age were selected, 20 men and women, respectively, and randomly divided into 4 groups. After written consent of the subjects was obtained, the whitening enzyme drink containing the small molecule peptides and various enzymes was taken 2 times a day for 3 months. After 3 months, the melanin index of the skin was determined using a skin melanin and heme tester (purchased from Beijing gold Hongshan commerce, Inc., model MeXAMETER MXI 8).
2. Test for improvement of color spots (visual age)
The state of significant unevenness in color of the adjacent skin was defined as a stain. The color pattern obtained by image analysis is a color standard in the industry, and various colors are obtained by changing 3 color channels of red, green and blue and superposing the color channels, and the color spots are calculated on the basis of the color pattern.
The subjects of 35-40 years of age were selected, 20 men and women, respectively, and randomly divided into 4 groups. After written consent of the subjects was obtained, the whitening enzyme drink containing the small molecule peptides and various enzymes was taken 2 times a day for 3 months. Pictures were taken using a skin image analyzer every 2 weeks before and after the start of the administration. The face and cheek portions of the picture were cut off at a size of 25mm × 20mm, and RGB color information at 100 positions in the image was obtained. The standard deviation was calculated from the values of R (red), G (green), and B (blue), respectively. The standard deviations of R (red), G (green), and B (blue) were multiplied to calculate a color deviation, which was defined as a degree of color unevenness.
In subjects in the stain improvement trial, a correlation linearity was made for each person with respect to age and degree of staining. Referring to application research of plum enzyme decomposition products in whitening cosmetics (Wangli, Tianzhongqinglong)' daily chemical science (11 months in 2014, 11 th period in 37), visual age is calculated in a simulated mode from the degree of color spots before and after taking whitening enzyme beverages containing small molecular peptides and multiple enzymes, and the value of visual age reduction is counted.
The mean of the group of subjects was taken as the final test result for each example.
The specific test results are shown in table 3.
TABLE 3 results table for melanin index and visual age decline values
After the whitening enzyme beverage containing the small molecular peptides and various enzymes is taken, the melanin index of the skin is obviously reduced. At the same time, the degree of mottling of the subjects was also improved. Wherein the effect of improving mottle after 3 weeks is more remarkable than that after 2 weeks. In example 5, the mean visual age of the subjects decreased by 1.65 years and 4.12 years after 2 months and 3 months of administration, respectively.

the fermentation bacteria are prepared from saccharomyces cerevisiae, streptococcus thermophilus and lactobacillus plantarum according to a mass ratio of 1: 1: 1, mixing;
II preparation of component B: removing mould grains and impurities in the buckwheat under aseptic conditions; carrying out ultraviolet sterilization on the buckwheat and the brown sugar for 30 minutes, and mixing the sterilized buckwheat and the sterilized brown sugar according to the weight ratio of 1: 1, putting the buckwheat into a fermentation tank, and mixing the buckwheat and water according to a weight ratio of 1: 10 adding water, then adding honey accounting for 4 percent of the weight of the buckwheat, inoculating selenium-enriched yeast accounting for 3 percent of the weight of the buckwheat, and stirring at 200 revolutions per minute to uniformly mix the raw materials; fermenting in dark at 18 deg.C for 15 days to obtain fermentation liquid; centrifuging the fermentation liquor at 4000 rpm for 25 minutes, and taking supernatant to obtain a component B;
III, seasoning: mixing the component A and the component B according to the mass ratio of 1: 4, uniformly mixing, adding 8 percent of white granulated sugar and 0.1 percent of lactic acid, stirring for 30 minutes at 200 r/min, adding 0.05 percent of sodium alginate and 0.10 percent of sodium stearoyl lactylate, and continuously stirring for 3 minutes at 200 r/min to obtain the whitening ferment beverage containing the small molecular peptides and the multiple enzymes.
The whitening ferment beverages of examples 5-7 containing small-molecule peptides and various enzymes were evaluated for centrifugal sedimentation rate and sensory score.
1. Determination of centrifugal Settlement Rate
Accurately weighing 10mL of beverage to be measured, adding the beverage to a centrifugal tube with scales, centrifuging the beverage for 20 minutes at 3500 rpm, discarding the upper solution, standing the beverage for 5 minutes, and accurately weighing the mass of the precipitate.
The calculation formula is as follows: the centrifugal sedimentation rate (%) — the mass of the sediment/the mass of the beverage to be measured × 100%.
2. Sensory evaluation
The sensory scoring of the beverage to be tested is carried out from four aspects of tissue state, color, aroma and taste, and the standard is as follows:
organization (20 points): uniform and non-layering, no precipitation bubbles and foreign matters, 18-20 min; layering, wherein a small amount of precipitate is formed, no bubbles or foreign matters exist, and the weight is 15-17 min; layering, wherein a small amount of precipitates, bubbles and foreign matters exist, and the number of the precipitates is 12-14; layering, namely, putting a large amount of precipitates with bubbles and foreign matters for a long time, wherein the number of the precipitates is less than 12;
color (10 min): the color is uniform and consistent, and is bright, 8-10 minutes; the color is relatively uniform, and is 6-7 minutes; the color is locally uneven, and is divided into 4-5 parts; the color and luster are not uniform and dark, and are less than 4 minutes;
fragrance: the fermentation is mellow, and is 28-30 minutes; the fermentation is mild in mellow fragrance, and the fermentation is carried out for 24-27 min; the fermentation is mellow and light in fragrance or slightly peculiar in smell, and is divided into 20-23 min; the fermented product is light in mellow fragrance and has a bad flavor which is less than 20 minutes;
and (3) taste: the sweetness is moderate, and is 36-40 minutes; slightly sweet, 30-35 points; less, 24-29 points; peracid, less than 24 minutes.
The specific test results are shown in table 4.
