[0035] The oral composition of the present invention can be manufactured by adding other components as needed and by known methods such as mixing.

[0036] The oral composition of the present invention is particularly preferably used as a granule. The granulated composition has improved dispersibility in liquids and ease of drinking, making it suitable for use as a powdered beverage, and can be used as a beverage granule. A beverage granule refers to a granule (a powdered beverage that is a granule) that consumers mix with a liquid such as water, hot water, milk, or soy milk when ingested and consume as a beverage.

[0037] The granulation method is not particularly limited and can be appropriately selected from granulation methods commonly used by those skilled in the art. Examples include fluidized bed granulation, extrusion granulation, rolling granulation, and agitation granulation. Regardless of the granulation method, granulated material can be produced by using any granulation apparatus available on the market and appropriately setting various manufacturing conditions such as drying temperature. From the viewpoint of obtaining granulated material with excellent ease of granulation and dispersibility, fluidized bed granulation is particularly preferred. Fluidized bed granulation is a method in which powder particles to be used as raw materials are fluidized by blowing air onto them and spraying a binding liquid such as water, thereby binding the powder particles together and forming granulated material, which is an aggregate of powder particles. [Examples]

[0038] The present invention will be described in more detail below based on examples, but the present invention is not limited thereto. [Test 1] The cell-activating 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-activating activity, it is possible to confirm cosmetic effects such as improved skin hydration through the maintenance and improvement of skin function.

[0039] The test substances used in this experiment are as follows: For the collagen, we used commercially available fish-derived collagen and pig-derived collagen. Specifically, we used fish-derived collagen peptide, which was obtained by washing fish scales and skin with water, extracting with hot water, breaking it down into low molecular weight molecules with enzymes, purifying it, and then powdering it. We also used pig-derived collagen peptide, which was obtained by washing pigskin with water, acid-treating it, extracting gelatin with hot water, breaking it down into low molecular weight molecules with enzymes, purifying it, and then powdering it.

[0040] For the barley grass, dried and pulverized young barley grass powder (manufactured by Toyo Shinyaku Co., Ltd.) was used. Specifically, fresh young barley grass was cut, blanched, dried, and then pulverized, and the dried and pulverized powder that passed through a sieve with a mesh size of 1 mm or less was used.

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

[0042] Commercially available beet oligosaccharides (raffinose) and isomaltoligosaccharides were used as oligosaccharides.

[0043] Commercially available Bifidobacterium longum and Bacillus coagulans (spore-forming lactic acid bacteria) were used as lactic acid bacteria. Specifically, Bifidobacterium longum was used as a dried powder of live bacteria with a bacterial count of 150 billion cells / g or more, and Bacillus coagulans (spore-forming lactic acid bacteria) was used as dried bacterial cells with a lactobacillus spore count of 6 billion cells / g or more.

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

[0045] The specific experimental procedure is as follows: (1) 75cm in a 37℃, 5% CO2 incubator 2 Commercially available normal human dermal fibroblasts were cultured in flasks. The culture medium used was 10% FBS-DMEM.

[0046] (2) Cells suspended by trypsin treatment, 75 cm 2 Transfer 1.5 × 10⁶ of liquid from the flask to a 96-well plate. 3 Cells were seeded at a cell density of cells / well and pre-cultured for 24 hours in a 37°C, 5% CO2 incubator.

[0047] (3) After removing the culture medium, the test substances were mixed in the ratios shown in Table 1 below, and 100 μL / well of the culture medium containing the test substances was added. The mixture was then incubated at 37°C in a 5% CO2 incubator for 24 hours.

[0048] (4) After 24 hours of incubation, the culture medium was removed and the mixture was 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 cells were allowed to stand in a 37°C, 5% CO2 incubator to stain them appropriately. (6) After culturing, the MTT solution was removed and the mixture was washed with PBS.

[0049] (7) 100 μL / well of isopropanol was added, and it was confirmed that the dye had eluted extracellularly. The absorbance at 570 nm and 650 nm was then measured.

[0050] (8) Based on the obtained data, the percentage of control (relative number of viable cells with the number of viable cells in the control set to 100%) was calculated, and the cell activation activity was evaluated for each example and comparative example. The results are shown in Table 1 as relative values ​​with the value of Comparative Example 1 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 showed synergistically improved cell activation activity compared to the compositions of the comparative examples that did not contain some of the components of the present invention. Specifically, comparing Comparative Example 1, which contained two components and did not contain water-soluble dietary fiber, lactic acid bacteria, and oligosaccharides, with Examples 1 and 2, which contained five components including collagen and barley grass in addition to these, Examples 1 and 2 showed improved cell activation activity. Similarly, comparing the results of Examples 1 and 2 and Example 3, the addition of two types of collagen further improved cell activation activity. Similarly, comparing the results of Examples 3 and 4, the addition of two types of lactic acid bacteria and two types of oligosaccharides further improved cell activation activity. Furthermore, comparing the results of Examples 3 and 5 and 6, the addition of ceramide or acerola further improved cell activation activity. Finally, comparing the results of Examples 4-6 and Example 7, the addition of ceramide and acerola particularly improved cell activation activity. The composition of the present invention has been shown to enhance the cell-activating activity of normal human dermal fibroblasts, which are an excellent model system for studying cell physiology, and has been confirmed to exhibit cosmetic effects such as improved skin hydration through the maintenance and improvement of skin function.

[0054] [Exam 2] The present invention's composition was used to confirm the collagen absorption-promoting effect of monolayer permeability in human colorectal cancer-derived cell lines. Monolayer permeability in human colorectal cancer-derived cell lines is a common in vitro model used to evaluate the absorption of compounds through the human gut. By confirming collagen permeability, it is possible to confirm cosmetic effects such as improved skin firmness and elasticity due to enhanced collagen absorption.

[0055] The test substance used in this experiment was the same as that used in Test 1.

[0056] The specific experimental procedure is as follows: (1) 75cm in a 37℃, 5% CO2 incubator 2 Commercially available human colorectal cancer-derived cell lines were cultured in flasks. The culture medium used was 10% FBS-1% NEAA-DMEM.

[0057] (2) Place 4 × 10 cells, suspended by trypsin treatment, into insert wells on a 24-well plate. 4 Cells were seeded at a cell density of cells / well and pre-cultured for 24 hours in a 37°C, 5% CO2 incubator. (3) After 24 hours, the culture medium was changed, and thereafter the culture was continued for 21 days, changing the medium every 3-4 days, until a monolayer was formed. (4) After the monolayer was formed, the electrical resistance was measured and the material was washed with HBSS buffer.

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

[0059] (6) The amount of collagen in the permeate was measured using a commercially available kit, and the collagen absorption amount is shown in Table 2 as a relative value with the value of Comparative Example 2 set to 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 compositions of the comparative examples that did not contain some of the components of the present invention. Specifically, comparing Comparative Example 2, which contained two components and did not contain water-soluble dietary fiber, lactic acid bacteria, and oligosaccharides, with Examples 8 and 9, which contained five components including collagen and barley grass in addition to these, collagen absorption improved in Examples 8 and 9. Similarly, comparing the results of Examples 8 and 9 and Example 10, the addition of two types of collagen further improved collagen absorption. Also similarly, 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, comparing the results of Examples 10 and Examples 12 and 13, the addition of ceramide or acerola further improved collagen absorption. Finally, comparing the results of Examples 11-13 and Example 14, the addition of ceramide and acerola particularly improved collagen absorption. The composition of the present invention improved the monolayer permeability of collagen in human colon cancer-derived cell lines, a common in vitro model used to evaluate the absorption of compounds via the human gut. As a result, it was confirmed that the composition exhibits cosmetic effects such as improved skin firmness and elasticity through enhanced collagen absorption.

[0062] [Exam 3] The taste-improving effect was confirmed using the composition of the present invention. The test substance used in this experiment was the same as that used in Test 1.

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

[0064] <Collagen-specific odor> ◎: It has no unpleasant odor and tastes considerably better than the standard product. ○: It has less of an unpleasant odor and tastes better than the standard product. △: Comparable to the standard product. ×: Below standard quality.

[0065] <Smooth throat feel> ◎: It has a smooth texture and feels much easier to drink than the standard product. ○: It has a smooth texture and feels easier to drink than the standard product. △: Comparable to the standard product. ×: Below standard quality.

[0066] <Texture> ◎: It has a pleasant texture and feels considerably easier to drink than the standard product. ○: It has a pleasant texture and feels easier to drink than the standard product. △: Comparable to the standard product. ×: Below standard quality.

[0067] <Aftertaste> ◎: It has a pleasant aftertaste and leaves the mouth feeling much cleaner than the standard product. ○: It has a pleasant texture and a cleaner taste compared to the standard product. △: Comparable to the standard product. ×: Below standard quality.

[0068] "comprehensive evaluation" The overall evaluation was determined based on the following criteria, considering the characteristic odor of collagen, throat feel, texture, and aftertaste. The results are shown in Table 3 above. ◎: Excellent, with no × or △ marks. ○: There are no × or △ marks, indicating a good result. △: There are △'s but no ×'s, so it is acceptable. ×: There is one or more × marks, so it is not acceptable.

[0069] [Table 3]

[0070] As shown in Table 3, the compositions of the examples containing the five components of the present invention showed improved taste compared to the comparative examples that did not contain some of the components of the present invention. Specifically, when comparing Comparative Example 3, which contained two types of collagen and did not contain other components, with Comparative Example 4, which also contained barley grass, the collagen odor was reduced in Comparative Example 4, but other evaluation items such as throat feel were about the same as in Comparative Example 3. On the other hand, Example 15, which contained the five components of the present invention, was superior in all evaluation items when compared with the results of Comparative Examples 3 and 4. In other words, while the taste improvement effect was insufficient with just two components, collagen and barley grass (Comparative Examples 3 and 4), the addition of water-soluble dietary fiber, lactic acid bacteria, and oligosaccharides to make a total of five components improved the taste in all evaluation items. Furthermore, when comparing the results of Examples 15 and 16, it was found that by using lactic acid bacteria and two types of oligosaccharides, and adding ceramide and acerola, the taste was further improved, resulting in a superior, easy-to-drink composition.

[0071] [Manufacturing Examples 1-3] (Manufacturing of powdered beverages) As shown in Table 4, collagen and other raw materials were mixed and granulated to produce a powdered beverage. When 5g of the resulting powdered beverage was mixed with 150mL of water and consumed, it was found to have excellent effects in maintaining and / or improving skin moisture and firmness, and was easy to drink.
