Description

Composition for improving skin moisturizing including royal jelly {Composition for improving skin moisturization comprising royal jelly}

The present invention relates to oral food compositions and cosmetic compositions for improving skin moisturizing, including a freeze-dried royal jelly, or a freeze-dried royal jelly treated with protease and non-starch polysaccharide degrading enzyme as an active ingredient. .

With the development of medicine, increased income and improved quality of life, there is a growing interest in improving health and maintaining beauty, and there is a growing social demand for food ingredients that can be safely consumed for a long time.

In order to contribute to the health of the people and contribute to the national economic development, the health functional food law was enacted in 2003, and as of 2010, the health functional food market in Korea exceeded 1 trillion won, and the individual certified health functional food material market was more than 15 times ( Compared to 2006).

However, royal jelly, which has been treated as a precious medicine for a long time and has various efficacy reports, has been excluded from health food general notification materials due to the lack of scientific efficacy verification, which is contrary to the activation of the functional food industry.

In addition, domestic royal jelly production is greatly shrunk due to the import of cheap Chinese royal jelly due to the full-fledged opening of agriculture such as FTA, and is facing difficulties in converting high value-added industries such as systematization of production and lack of product diversification.

Royal jelly is widely recognized as a nourishing tonic, with reports on the prevention of hyperlipidemia and atherosclerosis, fatigue, relieving liver and kidney toxicity, anti-aging, antioxidant, immune enhancement, antidiabetic, anti-cancer, anti-inflammatory, neuroprotective. However, on the other hand, allergy-induced allergy-induced specific protein of royal jelly has been reported. In addition, the scientific evidence supporting the positive efficacy of royal jelly is limited in vitro, and there are no reports on skin efficacy in humans.

In addition, the cosmetic composition for improving the skin condition is composed of a formulation that is applied to most of the skin, there was a cumbersome and sticky inconvenience when applied to the skin. In addition, there is a problem in that the portability is lowered and the efficacy of lowering the body absorption rate when applied to the skin.

Therefore, there is a need for the development of oral royal jelly excellent in improving the absorption of the body while improving the skin moisturizing effect while reducing allergy induction.

Accordingly, the present inventors have been found to be effective in improving skin moisturizing and antioxidant activity by ingesting royal jelly and allergy-induced protein-treated royal jelly by protein and carbohydrate degrading enzymes for healthy men and women who are in their 30s and older as skin aging progresses. The present invention was completed by convincing the possibility of developing into a functional dietary material for skin health. In addition, we analyzed the changes in sebaceous membrane lipids including ceramide, which is a biomarker of moisturizing, and free amino acid, which is a major natural moisturizing factor, to confirm the mechanism for enhancing skin moisturizing. Newly announced.

After extracting amino acids from the skin using tape strips (22-mm D-SQUARE Tape; Cu-Derm Co., USA) on the fore arm, chloroform / Methanol (2 : 1, v / v)) solution was extracted using sonication for 2 hours. The amino acid collected from the tape was measured by using distilled water to separate the layers, and then using L-amino acid quantitation colorimetric / fluorometric kit (Biovision Co., USA). Take 5 μL of standard and extract for each concentration and dispense into 96 well plate, and then 45 μL of assay buffer and 50 μL of master reaction mix (assay 46 μL of buffer), 2 μL of probe (pprobe) and 2 μL of enzyme mix were added and mixed well. Afterwards, a 96 well plate was wrapped in foil to block light and reacted at 37 ° C. for 30 minutes, followed by ELISA reader (VICTOR X3, PerkinElmer Co., Singapore) at 535/590 nm. Measured.

Experimental Example  11: Biopsy  Tissue Acquisition and Histological Examination

At week 10, applicants received a description of the biopsy and a consent for donation of human derivatives, followed by local anesthesia on the folding area inside the arm at Kyung Hee University Hospital Dermatology using a 2mm biopsy punch to remove the epidermal biopsy tissue. Taken and stored at -20 ° C until analysis. Skin tissue was cut / fixed to a thickness of 5 μm and stained with hematoxylin and eosin (H & E). The epidermal proliferation was visually measured by measuring the thickness of three epidermis in each tissue using a microscope. In addition, the quantitative change of collagen in the skin due to stainability was observed by Masson trichrome staining.

Experimental Example  12: Statistical Analysis

Descriptive statistics of all data obtained from human trials were conducted using the SPSS 18.0 program (SPSS Inc., Chicago, IL, USA). Data from all subjects were performed as a two-sided test at the significance level of 0.05 using a paired T test of measurement results before and after ingestion (weeks 0-5 or 0-10 weeks). The number of final subjects in each group after the 10-week intake period is not the same (placebo group: n = 14, RJ1 group: n = 17, RJ2 group: 16). Absolute change in each measurement parameter. Significance between groups was determined using ANOVA and Tukey's honestly significance difference (HSD) for unequal sample size.

Example  1: Obtain test subjects

The first subjects selected based on the exclusion criteria of the human application test with the consent form were obtained: 19 placebo groups, 17 lyophilized royal jelly groups (RJ1 group), and lyophilized royal jelly groups (RJ2 group). A total of 52 people were 16 (see Table 1).

During ingestion period, 2 patients at 1-5 weeks, 3 patients at 6-10 weeks, and 5 patients were dropped out. The reason for this was subjective judgment of no efficacy of the food. The final subjects after ingestion were 47 in placebo group, 17 in RJ1 group and 16 in RJ2 group. The mean age of each group was in the early 40's, and there was no significant difference between the groups. The Body Mass Index (BMI) was 21-23 (kg / m 2 ), which was normal.

At week 0, the skin moisturization of the placebo group at week 5 and 10 was slightly decreased but was not statistically significant. On the other hand, the RJ1 group and the RJ2 group increased skin moisturization at the 5th and 10th weeks, and the increase effect was especially greater in the RJ2 group (see Table 3).

4 Significance before and after ingestion (week 0) by student's paired t-test

As a control group, there were significant differences between the groups of skin moisturizing changes in RJ1 and RJ2 groups at week 5 and week 10. In the case of RJ1, the increase in moisturization was slightly slower at week 10 (p = 0.021) than at week 5 (p = 0.012). On the other hand, the increase in skin moisturization of RJ2 group was greater at week 10 (p = 0.000) than at week 5 (p = 0.006). This result shows that while RJ1 intake causes rapid increase in moisturizing, while the degree of moisturizing increase is moderate, the improvement of moisturization by RJ2 intake is not rapid, but the effect of moisturizing in long-term use is more than that of RJ1 intake. It means to appear large.

The oil content of the skin did not change between groups. Healthy skin is slightly acidic and is known to increase acidity with disease development (Behne MJ, Barry NP, Hanson KM et al. J Invest Dermatol 120 (6): 99801006 (2003)). Intake of RJ1 and RJ2 groups significantly decreased acidity at week 5 and 10, but there was no significant difference between the groups.

Example  4: Royal jelly  Skin by ingestion Antioxidant activity  change

Tryptophan, NADH, flavin, porphyrin, keratin, collagen, elastin, etc., present in the skin release autofluorescence in the skin (Portugal-Cohen M , Soroka Y, Frui-Zlotkin M et al. Exp Dermatol 20: 749-755 (2011)), and their analysis of autofluorescence differences is an indicator of the degree of oxidation and antioxidant activity of skin depending on the surrounding micro-hazardous environment. It can be used as. These substances in the skin can be monitored primarily in the green (G) visible light region at 530 nm wavelength. The sensitivity of self-fluorescence was measured by measuring the antioxidant capacity of the inner arm and the outer arm which are almost irradiated with UV radiation using Ecoskin self-fluorescence measuring device. Both G values) and area% of the G full spectrum showed no change between groups (see Table 4).

The blood concentration of vitamin E, a fat-soluble antioxidant vitamin, was increased in all groups, and there was no significant difference between the groups. On the other hand, the blood concentration of vitamin C, a water-soluble antioxidant vitamin, was significantly increased at week 10 in the RJ1 and RJ2 groups, and the increase was greater in the RJ2 group. Vitamin C is involved as a coenzyme of ceramide synthase (CerS), an enzyme related to de novo production of ceramide (Cer), a moisturizing biomarker of skin, in addition to its antioxidant activity. Has been suggested as an indirect blood indicator of skin health or moisturizing (Uchida Y, Behne M, Quiec D et al. J Invest Dermatol 117: 1307-1313 (2001)). The moisturizing effect of the group and the blood vitamin C concentration increase effect is a result confirming that the vitamin C concentration of blood has a high correlation with the skin moisturizing.

Example  6: Royal jelly  By ingestion Sebaceous membrane  Change in lipid content

Lipids in the sebaceous membrane, the outermost layer of the epidermis, are a mixture of triglyceride (TG), cholesterol (cholesterol (Chol)), free fatty acid (FFA), and ceramides (Cer). Among them, FFA and Chol are produced and secreted in both the epidermis and sebaceous glands, TG is produced in the sebaceous glands and Cer is produced only in the epidermis, respectively (Clarys P, Barel A. Clin dermatol 13: 307-321 (1995)).

After extraction using skin patch, the lipid changes of sebaceous membrane were identified through HPTLC. Total lipids were significantly increased only in RJ1 group, and there was no change in placebo and RJ2 groups before and after ingestion. 6).

There was no significant change in all sebaceous lipids (TG (triglycerides), Chol (cholesterol), FFA (free fatty acids) and Cer (ceramide)) in the placebo and RJ2 groups after the 10-week intake period. On the other hand, in the RJ1 group, Chol (p = 0.06, see Table 6), FFA (p = 0.001, see Table 6) and Cer (p = 0.000, see Table 6) of sebaceous membrane lipids significantly increased. p = 0.013, see Table 6) The Cer content (p = 0.000, see Table 6) was significant between the groups. Chol is a lipid that is produced and secreted from both the epidermis and sebaceous glands, whereas ceramide is a lipid produced and secreted only from the epidermis and the folding area inside the arm where biopsy is taken is not an area of sebaceous gland development. Increased skin moisturization is due to increased ceramide production and cholesterol, which are the major constituent lipids of the sebaceous membrane, which play a major role in maintaining the sebum membrane's lamella integrity.

On the other hand, despite the increase of vitamin C concentration in blood, which is suggested as an indirect indicator of moisturizing with skin moisturization and ceramide de novo production after RJ2 ingestion for 10 weeks, all sebaceous lipid content did not change. It suggests the possibility of causing changes in Natural Moisturizing Factor (NMF), another biomarker of skin moisturizing rather than lipids. Natural moisturizers are mixtures containing lactic acid, free fatty acids and free amino acids (Rawlings AV, Harding CR Dermatol Ther 17 (suppl 1): 43-48 (2004), Verdier-Svrain S, Bont F. J Cosmet Dermatol 6 ( 2): 75-82 (2007)), free fatty acids showed no change after RJ2 intake. Intake of RJ2 suggests that it may lead to a change in the content of natural moisturizing factors, such as free amino acids, rather than lipid components such as ceramides and free fatty acids, ultimately enhancing moisturization.

3 disposed one won ANOVA (one way ANOVA) and the significance between groups by Tukey's honestly significance difference (HSD) for unequal sample size

4 Significance before and after ingestion (week 0) by student's paired t-test

The total free amino acid content extracted using the Skin Patch was measured using L-amino acid quantitation colorimetric / fluorometric kit. The total free amino acid content was little changed. On the other hand, the total free amino acid content of the RJ2 group was significantly increased (p = 0.029, Table 7 and Figure 2), and as a result showed a significant difference between the groups (p = 0.042, Table 7). Total free amino acids, along with ceramides as the skin's main natural moisturizing factor, are the major biomarkers of skin moisturization. Total free amino acids significantly increased by RJ2 intake means that the increase in moisturization by RJ2 ingestion was due to an increase in the content of free amino acids, as well as the results of content of ceramide and free fatty acids that did not change before and after RJ2 intake.

Example  8: Royal jelly  Histological changes due to ingestion

The thickness of the epidermis varies by body part (75-150 μm), but this decreases with aging. In addition, skin aging is known to cause the production and secretion of collagen, a collagen protein, in the dermis. The thickness of the stratum corneum, the outermost layer of the epidermis measured after H & E staining in the biopsy tissues obtained from volunteers in each group did not change, but the thickness of the epidermis was significantly increased compared to the placebo group (Fig. 1 and Table 8). On the other hand, the density of collagen fibers in the dermis, which was examined by Masson trichrome staining, was increased in the RJ2 group.
