[0073] S6: placing the fermentation solution in a natural fermentation container and fermenting at room temperature for at least 7 days, and then filtering to obtain a lotus root extract;
[0074] S7: storing the lotus root extract after sterilization for later use, or drying the lotus root extract at low temperature to make lotus root extract for storage.
[0075] It should be noted that the lotus root extract can be directly used in cosmetics after sterilization, and the sterilization conditions of the lotus root extract are low-temperature sterilization at 50°C for 30 minutes, and then high-temperature sterilization at 120°C for 20 seconds.
[0076] The starch content, transparency and swelling degree of lotus root powder and lotus root extract made by the method of embodiments 1-3 were determined.
[0077] In the present application, the determination of starch content is carried out according to the determination method of GB 5009.9-2016 "National Food Safety Standard Determination of Starch in Food". The specific method is acid hydrolysis method. After removing fat and soluble sugars from the sample, the starch therein is hydrolyzed into monosaccharides with reducing properties by acid, and then the reducing sugar is determined and converted into starch.
[0078] The determination method of transparency is as follows: 1 g of lotus root powder, 1 g of lotus root extract A prepared by the method of Example 1, 1 g of lotus root extract B prepared by the method of Example 2 and 1 g of lotus root extract C prepared by the method of Example 3 are taken, and pure water is added to prepare 1% lotus root powder solution, 1% lotus root extract solution A, 1% lotus root extract solution B and 1% lotus root extract solution C, respectively. After being placed in a 100℃ condition for 15 minutes, then cooled to 25 degrees, TU-1810S ultraviolet visible spectrophotometer is used to determine the transmittance of lotus root powder solution, lotus root extract solution A, lotus root extract solution B and lotus root extract solution C at wavelength 620nm with distilled water as blank.
[0079] The determination method of swelling degree is as follows: 0.5g of dry starch is mixed with 25ml of distilled water in a pre-weighed 50ml centrifuge tube, and then oscillated in a 95℃ water bath for 30 minutes. Then, the supernatant is discarded after centrifugation at 3000r / min for 15 minutes, and the mass of the precipitate after centrifugation is weighed. The swelling degree of the sample is calculated according to the following formula:
[0080] Swelling degree / % = mass of precipitate after centrifugation / sample mass*100
[0081] Statistical analysis: measurement data is expressed as mean +- standard deviation, and SPSS software is used for statistical analysis. If the variance of measurement data is homogeneous, single factor analysis of variance is used; the least significant difference method is used for comparison between groups; if the variance of measurement data is not homogeneous, single factor analysis of variance is used for test, P<0.05 is considered to have statistical significance.
[0082] The specific determination results are shown in Table 1:
[0083] Table 1 Physical and chemical index determination data of lotus root powder and lotus root extract
[0084] Test article Starch content / % Transparency / % Swelling degree / % Lotus root starch 32.15±0.65 21.81±0.14 823.64±31.50 Example 1 10.14±0.71* 32.41±1.13* 1110.12±64.29* Example 2 10.45±0.65* 31.82±1.08* 1113.06±65.18* Example 3 10.04±0.68* 32.55±1.25* 1109.65±63.73*
[0085] Example 1, Example 2 and Example 3 are compared with the comparative lotus root powder, and the difference is statistically significant.
[0086] As shown in Table 1, the starch content of lotus root powder extract is obviously lower than that of lotus root powder, and the transparency and swelling degree of lotus root powder extract are obviously higher than those of lotus root powder with the same mass, so lotus root powder extract is more suitable for being used as a cosmetic raw material to prepare cosmetics.
[0087] The moisture retention function of lotus root powder and lotus root extract prepared by the method of Examples 1-3 was determined by using lotus root powder as a comparative example, and the specific determination method is as follows:
[0088] 1 g of lotus root powder, 1 g of lotus root extract A prepared by the method of Example 1, 1 g of lotus root extract B prepared by the method of Example 2 and 1 g of lotus root extract C prepared by the method of Example 3 were respectively weighed and dispersed in 15 ml of distilled water, and then were respectively placed in a water bath at 45℃, 55℃, 65℃, 75℃ and 85℃ for heating for 30 min, and then were cooled to 25 degrees, and then were centrifuged at 3000 r / min for 15 min by using a centrifuge, and then the supernatant was discarded, and the mass of the precipitate was weighed. The moisture retention was calculated according to the following formula:
[0089] Moisture retention / % = mass of precipitate / sample mass*100
[0090] The specific determination results are shown in Table 2.
[0091] Table 2: Moisture retention determination data of lotus root powder and lotus root extract
[0092]
[0093] The lotus root molecules form hydrophilic colloids in water, and with the increase of temperature, the starch molecules are gradually gelatinized and broken to generate more hydrogen bonds. As shown in Table 2, the moisture retention of lotus root powder and lotus root extract is roughly the same in the temperature range of 45-75℃, but in the temperature range of 75-85℃ close to the gelatinization temperature, the moisture retention of lotus root extract is higher than that of lotus root powder, because a large amount of water is absorbed in the starch gelatinization process. Finally, under the condition of 85 degrees, the moisture retention of lotus root powder is about 1200%, and the moisture retention of lotus root extract is more than 1500%. Therefore, it can be seen that the moisture retention of lotus root extract is higher than that of lotus root powder.
[0094] Example 4
[0095] The moisturizing water provided by Example Four of the present application is mainly prepared by mixing the following components in parts by weight: 5 parts of lotus root extract, 5 parts of glycerol, 1 part of 1% hyaluronic acid, 1 part of tremella polysaccharide and the balance of ultrapure water.
[0096] The lotus root extract in the present example is prepared by the method of Example 1, Example 2 or Example 3.
[0097] Example 5
[0098] Example 5 provides a moisturizing water, which is mainly made by mixing the following components in parts by weight: lotus root extract 20 parts, glycerin 10 parts, 1% hyaluronic acid 5 parts, tremella polysaccharide 5 parts, and the balance of ultrapure water.
[0099] The lotus root extract in this example is the lotus root extract prepared by the method of Example 1, Example 2, or Example 3.
[0100] Example 6
[0101] Example 6 provides a moisturizing water, which is mainly made by mixing the following components in parts by weight: lotus root extract 1 part, glycerin 7 parts, 1% hyaluronic acid 2 parts, tremella polysaccharide 6 parts, and the balance of ultrapure water.
[0102] The lotus root extract in this example is the lotus root extract prepared by the method of Example 1, Example 2, or Example 3.
[0103] Experiment of moisturizing evaluation
[0104] According to the lotus root powder extract 1%, 5%, 10%, the balance is ultrapure water, and the moisturizing water of low, medium and high concentration groups is configured, which are marked as Comparative Example 1, Comparative Example 2 and Comparative Example 3, respectively, and then compared with the moisturizing water of Example 4, Example 5 and Example 6 and pure water.
[0105] Subject inclusion criteria: 20-55 years old, healthy, and qualified after inquiry, all of which can be used for observation. Subject exclusion criteria: those with severe systemic diseases, immune deficiency or autoimmune diseases; those with active allergic diseases; pregnant or lactating women; those who use hormone and immune agents during the test period; those who do not use the test material or have incomplete data. All subjects sign the informed consent form.
[0106] Before the test, the test site cannot use any product (cosmetic or external drug) for 2-3 days. During the experiment, the subjects clean the inner measurement of the forearm, mark the measurement area on the inner measurement of the forearm. Test environment conditions: the test environment temperature is 22±1℃, the humidity is 50±5%, no drinking water, the forearm is exposed, relaxed, and real-time dynamic detection is carried out;
[0107] The test area and the control area are measured by using the capacitance method skin tester. According to the experimental design, the TEWL value of each period is measured, and the skin water loss reduction calculation formula is as follows:
[0108] T% skin water loss reduction percentage = (skin water loss amount before use T0-T1 skin water loss amount after use) / skin water loss amount before use T0x 100%
[0109] Table 3 Amount of skin moisture loss (%)
[0110]
[0111]
[0112] Note: The negative value in the table represents the increase in the amount of skin moisture loss relative to T0; the positive value represents the decrease in the amount of skin moisture loss relative to T0.
[0113] As can be seen from Table 3, the low, medium and high concentration solutions prepared using the lotus root powder extract of the present application can effectively reduce the loss of skin moisture content, and can also play a moisturizing effect when used alone. The moisturizing effect of the moisturizing water prepared by adding the lotus root powder extract of the present application to other cosmetics with moisturizing effect, such as the moisturizing water of Example 4, Example 5 or Example 6 of the present application, is better.
[0114] The present application is not limited to the above-mentioned optional embodiments, and anyone can derive other various forms of products under the inspiration of the present application. The above-mentioned specific embodiments should not be understood as limiting the scope of protection of the present application, and the scope of protection of the present application should be defined by the claims, and the specification can be used to interpret the claims.
