Description

Technical Field

[0001] The invention belongs to the technical field of food, and in particular relates to a composition containing elastin peptide, a preparation method and application thereof. Background Art

[0002] Elastin plays the role of a rubber band in the skin, allowing the skin to stretch and fold. Its function is like the spring in a mattress, responsible for maintaining and supporting the elasticity of the skin. Therefore, elastin plays an important role in maintaining the elasticity of the skin. Elastin determines the elasticity and softness of the skin, and has the effect of preventing aging and promoting regeneration of the physiological aging process of the skin caused by physical and chemical factors such as light. Many people believe that the key to maintaining youthful skin is how to supplement collagen, but ignore another important substance in fibroblasts - elastin. If skin care products contain both elastin and collagen ingredients, it will have a very good effect on keeping the skin young, delicate and elastic.

[0041] The only difference from Example 3 is that blueberry juice powder is not included, and the amount thereof is added to the lily powder.

[0042] Experimental Example 1 6hpf wild-type AB strain zebrafish were randomly selected in a six-well plate, 3mL / 30 tails / well, and a normal control group, a model control group, a positive control group, Example 1-3, and a comparative example 1-6 group were set up. Except that the normal control group used fish culture water as the culture medium, the other groups all used fish culture water with a hydrogen peroxide concentration of 1mM as the culture medium; the positive control group was given a positive control drug 900U / mL catalase in water, and the Example 1-3 and the comparative example 1-6 groups were given 1µL / mL of the corresponding samples; the following tests were performed respectively: The samples were treated for 6 days, during which the medium was changed every day. After 6 days, the zebrafish in each experimental group were stained with a cell senescence β-galactosidase staining kit. After the staining, 10 zebrafish were randomly selected from each experimental group, fixed with 3% methylcellulose, observed and photographed under a stereomicroscope, and the β-galactosidase staining intensity (A) in the zebrafish was quantitatively counted using Image pro plus software. The statistical analysis results of this indicator were used to evaluate the ability of the sample to inhibit the enhancement of β-galactosidase activity induced by hydrogen peroxide. The statistical processing results are expressed as mean ± SE. GraphpadPrism software was used for drawing and statistical analysis. p<0.05 indicated that the difference was statistically significant. The calculation formula for the inhibition rate of β-galactosidase activity is: C=(A1-A2) / (A1-A0)×100%, where, C——β-galactosidase activity inhibition rate, %; A1——average coloring intensity of β-galactosidase in the model control group (n=10); A2——average value of β-galactosidase coloring intensity of the sample group (positive control drug or Examples 1-3 or Comparative Examples 1-6) (n=10); A0——Average value of β-galactosidase staining intensity in the normal control group (n=10).

[0043] Results: After the zebrafish were cultured in the normal control group, model control group, positive control group, Example 1-3 group, and Comparative Example 1-6 group, there was no death and no obvious abnormal toxicity. The results of the β-galactosidase activity test in zebrafish of each group are shown in Table 1.

[0044] Table 1: Results of β-galactosidase activity test in zebrafish of each group

[0045] Compared with the normal control group, ### P<0.001; compared with the model control group, *P<0.05, **P<0.01 between sample groups; compared with the Example 3 group, & P<0.05, && P<0.01.

[0046] The staining intensity of the model control group was higher than that of the normal control group, and the difference was extremely significant (P<0.001), indicating that the model was established very successfully. The administration of catalase, examples 1-3, comparative example 1, and comparative examples 3-6 could reduce the staining intensity of the model group, and the difference was statistically significant (P<0.05) or significantly different (P<0.01). The effects of each embodiment were equivalent to those of catalase and better than those of each comparative example.

[0047] The composition of the present invention has a better anti-aging effect when the components are composed of specific components and the components are in specific proportions.

[0048] Experimental Example 2 80 female subjects aged 40-55 years were selected and randomly divided into four groups: blank control group, trial group 1, trial group 2 and trial group 3, with 20 people in each group. Among them, trial group 1 took the drink of the composition of Example 3 of the present application, trial group 2 took the drink of the composition of Comparative Example 2 of the present application, and trial group 3 took the drink of the composition of Comparative Example 5 of the present application. Take 1 time in the morning and evening each day, 30 mL each time, for 30 consecutive days. Skin elasticity and moisture tests were performed before and after the experiment.

[0049] Among them, the skin moisture test uses a skin moisture content tester (model CM825, German CK company), and the skin elasticity uses a skin elasticity tester (model MPA580, German CK company). The test is carried out in a spacious, well-ventilated, stable environment with a temperature of (21±1)℃ and a humidity of 50%±5%. The test volunteers' skin (forehead) moisture and elasticity before consuming the beverage of the present invention (day 0) and 30 days after consuming it. Skin care products are prohibited on the day of measurement. Clean the tested area with a clean cotton ball dipped in distilled water in a quiet state. After wiping dry for 15 minutes, select 6 measurement points in the middle of the forehead and take the average value. The test of the same volunteer is completed by the same measurement personnel. The experimental results are shown in Table 2.

[0050] Table 2: Skin test results

[0051] Note: *P<0.05 for comparison before and after the test; **P<0.01 for comparison before and after the test.

[0052] The test results show that after 30 days of trial, the skin moisture of the subjects in the three trial groups was improved, and the skin elasticity of trial group 1 and trial group 3 was improved. Combining the improvement results of skin moisture and skin elasticity, the improvement degree of trial group 1 is the most significant, which is better than trial group 2 and trial group 3. The composition of the present invention has the ideal effect of increasing skin elasticity, anti-wrinkle, moisturizing, and increasing skin moisture, and its effect is significantly better than the comparative group sample obtained by changing the formula.

[0053] According to the above experimental results, the present invention uses the synergistic effect of the triple combination of fish collagen peptide and elastin peptide, pomegranate concentrated powder and cranberry concentrated powder, lily powder and blueberry juice powder to obtain a composition with a specific component composition and each component in a specific proportion, which has a better effect on improving skin elasticity and / or improving skin moisture and / or delaying wrinkle formation.
