[0036] The oral composition of the present invention is particularly preferably used as a granulated product. Granulated compositions have improved dispersibility in liquids and ease of drinking, making them suitable for use as powdered beverages, and can be used as granulated beverage products. A granulated beverage product refers to a granulated product (a powdered beverage product that is a granulated product) that is mixed with a liquid such as water, hot water, milk, or soy milk by a consumer at the time of ingestion and consumed as a beverage.

[0037] The granulation method is not particularly limited and may be selected from granulation methods commonly used by those skilled in the art. Examples include fluidized bed granulation, extrusion granulation, tumbling granulation, and stirring granulation. Regardless of the granulation method, a granulated product can be produced using any commercially available granulation device by appropriately setting various production conditions such as the drying temperature. From the viewpoint of obtaining a granulated product with excellent ease of granulation and dispersibility, fluidized bed granulation is particularly preferred. Fluidized bed granulation is a method in which raw material powder particles are fluidized by blowing air on them with an air flow, and then a binding liquid such as water is sprayed onto them to bind the powder particles together and form a granulated product, which is an agglomerate of the powder particles. [Example]

[0038] The present invention will be described in more detail below based on examples, but the present invention is not limited to these examples. [Test 1] The cell activation activity of normal human dermal fibroblasts (NHDF) was confirmed using the composition of the present invention. Normal human dermal fibroblasts are widely used as an excellent model system for studying cell physiology, and by confirming their cell activation activity, it is possible to confirm cosmetic effects such as improved skin moisturization by maintaining and improving skin function.

[0039] The test substances in this experiment are as follows: The collagen used was commercially available fish-derived collagen and pig-derived collagen. Specifically, fish scales and skin were washed with water, extracted with warm water, enzymatically decomposed into small molecules, purified, and powdered to produce fish-derived collagen peptides, and pig skin was washed with water, treated with acid, extracted with warm water, and the gelatin was enzymatically decomposed into small molecules, purified, and powdered to produce pig-derived collagen peptides.

[0040] The barley leaves used were dried and crushed powder of young leaves (manufactured by Toyo Shinyaku Co., Ltd.) Specifically, fresh young leaves were cut, blanched, dried, crushed, and passed through a sieve with openings of 1 mm or less.

[0041] As the water-soluble dietary fiber, we used commercially available indigestible dextrin made from tapioca starch, with a dietary fiber content of 38-45% as measured by enzyme-liquid chromatography.

[0042] As oligosaccharides, commercially available beet oligosaccharide (raffinose) and isomaltooligosaccharide were used.

[0043] The lactic acid bacteria used were commercially available Bifidobacterium longum and Bacillus coagulans (spore-forming lactic acid bacteria). Specifically, the Bifidobacterium longum was a dry powder of live bacteria with a bacterial count of 150 billion or more per gram, and the Bacillus coagulans (spore-forming lactic acid bacteria) was a dry bacterial cell with a lactobacillus spore count of 6 billion or more per gram.

[0044] The ceramide used was a commercially available rice-derived ceramide. Specifically, the extract powder containing 10% or more of glucosylceramide was obtained by extracting rice seeds from Oryza sativa Linne (Gramineae) with ethanol. As the acerola, commercially available concentrated acerola juice powder was used. As the dextrin, commercially available powdered dextrin was used.

[0045] The specific experimental procedures are as follows. (1) In a 37°C, 5% CO2 incubator, 75 cm 2 Commercially available normal human dermal fibroblasts were cultured in flasks using 10% FBS-DMEM medium.

[0046] (2) Cells suspended by trypsin treatment were collected at 75 cm 2 1.5 x 10 cells from a flask into a 96-well plate 3 The cells were seeded at a density of 100 cells / well and pre-cultured for 24 hours in a 5% CO2 incubator at 37°C.

[0047] (3) After removing the medium, the test substance was mixed at the ratio shown in Table 1 below, and 100 μL / well of the medium containing the test substance was added, followed by culturing for 24 hours in a 37°C, 5% CO2 incubator.

[0048] (4) After 24 hours of culture, the medium was removed and the cells were washed with PBS. (5) 100 μL / well of a 500 μg / mL MTT (Nacalai Tesque) solution prepared with serum-free DMEM was added to each well, and the plate was left to stand in a 37°C, 5% CO2 incubator to adequately stain the cells. (6) After incubation, the MTT solution was removed and the cells were washed with PBS.

[0049] (7) 100 μL / well of isopropanol was added, and after confirming that the dye had been eluted out of the cells, the absorbance at 570 nm and 650 nm was measured.

[0050] (8) Based on the obtained data, the % of control (the relative number of viable cells, with the number of viable cells in the control being 100%) was calculated, and the results of evaluating the cell activation activity for each Example and Comparative Example are shown in Table 1 as relative values ​​when the value for Comparative Example 1 is set to 100.

[0051] % of control = (Data sample - Data blank) / (Data control - Data blank) × 100

[0052] [Table 1]

[0053] As shown in Table 1, the compositions of the Examples containing the five components of the present invention exhibited synergistically improved cell-activating activity compared to the Comparative Examples, which did not contain some of the components of the present invention. Specifically, when comparing Comparative Example 1, which contained two components (water-soluble dietary fiber, lactic acid bacteria, and oligosaccharides) with Examples 1 and 2, which contained five components (collagen and young barley leaves) in addition to these, the cell-activating activity was improved in Examples 1 and 2. Similarly, when comparing the results of Examples 1 and 2 with those of Example 3, the cell-activating activity was further improved by adding two types of collagen. Similarly, when comparing the results of Examples 3 and 4, the cell-activating activity was further improved by adding two types of lactic acid bacteria and two types of oligosaccharides. Furthermore, when comparing the results of Examples 3, 5, and 6, the cell-activating activity was further improved by adding ceramide or acerola. Furthermore, when comparing the results of Examples 4 to 6 with those of Example 7, the cell-activating activity was particularly improved by adding ceramide and acerola. The composition of the present invention improved the cell activation activity of normal human skin fibroblasts, an excellent model system for studying cell physiology, and was therefore confirmed to exhibit cosmetic effects such as improving skin moisturizing by maintaining and improving skin function.

[0054] [Test 2] The composition of the present invention was used to confirm the collagen absorption-promoting effect of the composition on the monolayer permeability of a human colon cancer-derived cell line. Monolayer permeability of a human colon cancer-derived cell line is a common in vitro model used to evaluate the absorption of compounds through the human intestine. By confirming collagen permeability, cosmetic effects such as improved skin firmness and elasticity due to collagen absorption promotion can be confirmed.

[0055] The test substances used in this experiment were the same as those used in Test 1.

[0056] The specific experimental procedures are as follows. (1) In a 37°C, 5% CO2 incubator, 75 cm 2 A commercially available human colon cancer cell line was cultured in a flask using 10% FBS-1% NEAA-DMEM medium.

[0057] (2) Trypsinized cells were suspended and placed in insert wells of a 24-well plate at 4 × 10 4 The cells were seeded at a density of 100 cells / well and pre-cultured for 24 hours in a 5% CO2 incubator at 37°C. (3) After 24 hours, the medium was changed, and the cells were then cultured for 21 days, with the medium changed every 3 to 4 days, to form a monolayer. (4) After the monolayer was formed, the electrical resistance was measured and the plate was washed with HBSS buffer.

[0058] (5) Test substances were mixed at the ratios shown in Table 2 below, and 50 μL / well of medium containing the test substances was added. The cells were cultured for 2 hours in a 5% CO2 incubator at 37°C. HBSS buffer was used as the medium, and the total concentration of the test substances in the medium was 1000 μg / mL.

[0059] (6) The amount of collagen in the permeate was measured using a commercially available kit, and the amount of collagen absorption was shown in Table 2 as a relative value with the value for Comparative Example 2 taken as 100.

[0060] [Table 2]

[0061] As shown in Table 2, the compositions of the Examples containing the five components of the present invention synergistically improved collagen absorption compared to the Comparative Examples, which did not contain some of the components of the present invention. Specifically, when comparing Comparative Example 2, which contained two components (water-soluble dietary fiber, lactic acid bacteria, and oligosaccharides) with Examples 8 and 9, which contained five components (collagen and young barley leaves) in addition to these, collagen absorption was improved in Examples 8 and 9. Similarly, when comparing the results of Examples 8 and 9 with those of Example 10, the addition of two types of collagen further improved collagen absorption. Similarly, when comparing the results of Examples 10 and 11, the addition of two types of lactic acid bacteria and two types of oligosaccharides further improved collagen absorption. Furthermore, when comparing the results of Examples 10 with those of Examples 12 and 13, the addition of ceramide or acerola further improved collagen absorption. Furthermore, when comparing the results of Examples 11 to 13 with those of Example 14, the addition of ceramide and acerola improved collagen absorption in particular. The composition of the present invention improved the collagen monolayer permeability in a human colon cancer-derived cell line, a common in vitro model used to evaluate the absorbability of compounds through the human intestine, and was therefore confirmed to exhibit cosmetic effects such as improving skin firmness and elasticity by promoting collagen absorption.

[0062] [Test 3] The taste-improving effect of the composition of the present invention was confirmed. The test substances used in this experiment were the same as those used in Test 1.

[0063] Each sample was obtained by mixing 5 g of powder sample with 150 ml of water according to the blending ratios shown in Table 3. Of these samples, the sample obtained from the powder sample of Comparative Example 2 was used as the standard. The sensory evaluation was conducted by panelists who regularly consume green juice and have experience in sensory evaluation. The panelists were asked to evaluate the collagen-specific odor, throat feel, texture, and aftertaste.

[0064] <Collagen-specific odor> ◎: No odor and tastes much better than the standard product. ○: It has less odor and tastes better than the standard product. △: Similar to the standard product. ×: Below standard.

[0065] <Smoothness> ◎: It goes down smoothly and feels much easier to drink than the standard product. ○: It goes down smoothly and feels easier to drink than the standard product. △: Similar to the standard product. ×: Below standard.

[0066] <Texture> ◎: It feels smooth on the tongue and is much easier to drink than the standard product. Good: Feels smooth on the tongue and is easier to drink than the standard product. △: Similar to the standard product. ×: Below standard.

[0067] <Aftertaste> ◎: The aftertaste is good and the mouth feels much cleaner than the standard product. ○: The texture is good and the inside feels cleaner than the standard product. △: Similar to the standard product. ×: Below standard.

[0068] "comprehensive evaluation" The overall evaluation was based on the evaluation of the collagen-specific smell, throat feel, texture, and aftertaste, and was determined according to the following criteria. The evaluation results are shown in Table 3 above. ◎: Excellent, with neither × nor △. ◯: No X or △, good. △: There are △ marks but no × marks, so it is acceptable. ×: There is one or more ×s, and it is not possible.

[0069] [Table 3]

[0070] As shown in Table 3, the compositions of the examples containing the five components of the present invention had improved taste compared to the comparative compositions not containing some of the components of the present invention. Specifically, when comparing Comparative Example 3, which contained two types of collagen but no other components, with Comparative Example 4, which also contained young barley leaves, the collagen odor was reduced in Comparative Example 4, but other evaluation items such as smoothness were comparable to Comparative Example 3. On the other hand, Example 15, which contained the five components of the present invention, was superior in all evaluation items compared to the results of Comparative Examples 3 and 4. That is, while the taste-improving effect of the two components, collagen and young barley leaves, was insufficient (Comparative Examples 3 and 4), the taste was improved in all evaluation items by incorporating water-soluble dietary fiber, lactic acid bacteria, and oligosaccharides into the five components. Furthermore, comparing the results of Examples 15 and 16, it was found that by using two types of lactic acid bacteria and oligosaccharides and adding ceramide and acerola, the taste was further improved, resulting in a composition that was easy to drink.

[0071] [Production Examples 1 to 3] (Production of powdered beverages) As shown in Table 4, collagen was mixed with other ingredients, the composition was granulated, and a powdered beverage was produced. When 5 g of the resulting powdered beverage was mixed with 150 mL of water and ingested, it was found to be easy to drink and had excellent effects on maintaining and / or improving skin moisture and firmness.
