## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority from and the benefit of Korean Patent Application No. 10-2014-0108139, filed on Aug. 29, 2014, which is hereby incorporated by reference in its entirety.
BACKGROUND
1. Field
Exemplary embodiments relate to oriental medicinal collagen food and manufacturing method thereof, and, more particularly to, oriental medicinal collagen food and manufacturing method of the oriental medicinal collagen food for skin beauty enhancement.
2. Discussion of the Background
Wrinkles are one of the most common symptoms caused by loss of moisture and elasticity resulting from skin aging. Among many theories regarding skin aging, some of which causes are diseases, stress, ultraviolet, and oxidative reactive species which also occurs during normal metabolism. These result in lipid peroxidation, protein oxidation, cutting and abnormal crosslinking of elastic fibers such as collagen and elastin chain, and melanin production. These lead to oxidative damage to cells and tissues, accelerating decrease in skin elasticity, wrinkles, melasma, freckles, and other skin aging symptoms. After climacteric period, women experience decrease in female hormone excretion, which leads to drastic decrease in biosynthesis ability of collagen including skin, especially dermis, resulting from low female hormone level. To prevent skin aging, reinforcement of collagen biosynthesis ability or building anti-oxidation defensive system to remove and suppress oxidative reactive species are necessary.
The connective tissues of dermis closely related to skin aging mainly include collagen and elastin. The main protein in the connective tissues, collagen, includes 70-80% of dry weight of dermis providing elasticity, strength, and maintains moisture Decrease in collagen functionality from photoaging and intrinsic aging affects skin adversely by causing wrinkles, rough skin, less elasticity, dryness. As explained, collagen plays a vital, role in maintaining skin elasticity and moisture, which would come from the proteins essential to cell generation. Therefore in dietetics, consumption of quality protein is closely related to skin health.
Edible cosmetic supplements are mainly collagen products extracted from fish, meat, and vegetables. Collagen is a type of fibrous protein, a main nutrient for formation of form muscular tissue, skin tissue, bone tissue, cartilage and cornea. Among the constituents of proteins, hydroxyproline, glycine, and serine have great effects on skin elasticity and moisture retention. Korean pharmaceutical or cosmetic companies sell collagen products made from imported collagen from United States and Japan. For example, Chung-Gye Pharmaceutical's ‘Collagen Plus 3000,’ Han-Mi Pharmaceutical's ‘New Collagen,’ Je-II Pharmaceutical's ‘Collagen 100,’ and Citri's ‘Collagen 1000’ are all 100% or 99.9% made of imported collagens from the U.S. or Japan. Non-Korean products such as ‘Collagen Gold’ or ‘Pure Collagen SD’ are also made of pure collagen. Companies all over the world emphasize the collagen purity in selling their products. However, the problem lies on the lack of researches relating collagen consumption to increase in collagen content in human bodies.
In addition, there is another issue that the efficacy of edible collagen supplements is insufficiently proven objectively. There are not many researches whether consuming collagen increases the collagen contents in a human body. Korean Ministry of Food and Drug Safety (MFDS) keeps its stance at telling collagen can be used as a food ingredient but the relation between eating it and positive effect on skin is not scientifically proven.
Recently, collagen products with increased functionality by adding vitamin, beta-carotene, pomegranate, isopeulrabon from soybean, and others, are on market. ‘Collagen Crystal 100’ from Saerom Cosmetics is made of collagen from pork skin, ‘Jeju Horse Placenta Collagen’ is literally condensed from horse placenta, and ‘Low Molecular Weight Fish Collagen’ from Amore Aritaum has fish collagen raw compound outside of Korea. There are other products with collagen from stingrays, shark's fin, pig placenta or skin, or sheep placenta.
To strengthen connective tissues like muscle, skin, and bones, a traditional way Koreans used to consume collagen is making gelatin from heating animals or fishes with high collagen content followed by fermenting them. Collagen becomes viscous gelatin when heated. They consumed it in glue state for easy storage. The examples of edible glue are glue from donkey skin, glue made with antlers, glue from tortoise shell, glue from snapping turtle shell. Since these materials were expensive and hard to procure, they used chicken feet, which can be easily and massively purchased, to prepare gel from boiling. Other traditional ways of efficiently consuming collagen were eating fermented skates or cow knee knucklebone soup.
As explained, traditional ways of consuming collagen is deficient of proven efficacy from accurate clinical trials, and without examples or prescription specifically meant for skin health improvement. It is difficult to assess an appropriate price based on efficacy, not knowing why such high price has to be paid, Korean Patent No, 10-1361060, issued to University-Industry Cooperation Foundation at Konkuk University in Korea (Title of invention “Method of Collagen Extraction from Chicken Residual Parts”), maximizes extraction efficiency with swelling chicken skin in acid and alkali, controlling pH to edible range with neutralization, removing odor and unwanted ingredients with hot-water extraction, and prepare granulized collagen with freeze-dry for easy utilization. Korean Patent No. 10-0733081, issued to Hankook Foodifarnn Co., describing a method of preparing chondroitin sulfuric acid from chicken feet consist of heated extraction, centrifuge, condensation or condensing the top part from centrifuge after hydrolysis with proteolytic enzyme and inactivating the enzyme. The method to prepare nutrition boost extract and jelly involves boiling chicken feet with atractylodes, amomum anthioides wallich, and other gastrointestinal supplements Korea Food Research Institute obtained collagen by sonicating from fish skin. There is another way to prepare collagen product from collagen with molecular weight around 30,000-50,000 from a low-temperature and low molecular weight process.
However, the above mentioned products for edible beauty supplements do not produce sufficient collagen in a human body. Other processes that extract collagen from animal only try producing active ingredients using strong acids, hydrolysis, or boiling animal parts with oriental medicines helping digestion. These involve very complex procedures and produce a lot of industrial waste due to use of strong acid. Lack of theoretical evidence regarding collagen digestion and biosynthesis in a human body is another problem. The above information is only for enhancement of understanding of the background of the inventive concept. Thus, it may contain information that does not constitute the prior art that is already known to a person having ordinary skill in the art.

The main ingredients in this oriental medicinal collagen food for skin beauty enhancement may include collagen, chicken feet, dandelion, angelica gigas, and pueraria root. Their main nutrients, efficacy, main oriental medicinal theory are explained hereinafter.
Collagen: 25 percent of proteins in a human body is collagen. Collagen is the main substance for connective tissues such as bone, tendon, and muscle. Collagen forms a truss with its three branches of polymer protein bound strongly. It is not soluble to water, weak acid, or weak alkali, but becomes gelatin when boiled. The known efficacy of collagen is for osteoporosis, knee arthritis, brain development, skin beautification, moisture retention, increase in immunity, growth and development, arteriosclerotic, hemostasis, and vision improvement. Amino acids in collagen are proline, oxyproline, glycine, and glutamic acid. Pig feet, broth from boiled cow bones, chicken feet, pig skin, cow knee knucklebone soup contain high concentration of collagen.
Chicken feet: chicken feet include bone, joint, cartilage, tendon, and muscle, rich in potassium, marrow, protein, collagen, and other trace elements. Collagen is fibrous proteins including amino acids, which is mostly found in outer layer of organs, cartilage, teeth, hair, muscle, and skin. It strengthens joints. Chicken feet are not thick and in cartilage form. Cartilage parts has chondroitin, skin has glycoprotein such as glycine and protein for connective tissues such as collagen or elastin. Considerable mass of extracellular materials exists between connective tissues, and the species and array of these materials specify connective tissue proper, cartilage, bone, and blood. Among connective tissue proper, dermis is a loose connective tissue with dispersed collagen, a kind of fibrous collagen. Tendons connect muscles and bones, and are dense connective tissues with collagen densely arrayed in a regular or irregular manner. Chicken feet have been known for a long time to be good for degenerative joint arthritis. Its recently discovered beneficial effect on skin beautification and lowering blood pressure is due to increase in physiological activity from these nutrients.
Dandelion: taraxacums are perennial plants in astrales order. Different taraxacums are Taraxacum nonogolicum H. Mazz, Taraxacum ohwianum Kitamura, Taraxacum coreanum Nakai, and Taraxacum officinale Weber. They are used to remedy acute hepatitis, reinforce immune systems, protect liver, promote urination, and remedy mastitis, throat inflammation, swelling due to fever. They have 17 of all proteinogenic amino acids except cysteine, and other 8 essential amino acids. They are 1.4 to 1.8 times more abundant in leaves than roots. The leaves contain the following main constituents in order of its contents; glutamic acid, proline, phenylalanine, aspartic acid, arginine, leucine, lysine. Inorganics such as potassium and calcium are abundant along with magnesium, manganese, and iron.
Angelica gigas: angelica gigas are commonly used for blood-related disease because it promotes blood production. Angelica gigas Nakai, Angelica sinensis (Oliv.) Diels, Angelica acutiloba (Sieb. & Zuc) Kitagawa are commonly used. They promote blood flow in coronary arteries and production of red blood cells. The encyclopedia of basic agricultural plants of ancient China describes it tastes sweet, has warm traits, is not poisonous, warms body, stops pain, cure arthritis, are used when a pregnant woman has a sign of miscarriage or on their skin problems, protects five viscera, generates tendons and muscle. According to Compendium of Materia Medica, angelica gigas controls blood, is good for womanhood. They cure palsy, chi malfunction, and fatigue. They also remove bad blood and produce fresh blood. They are good for habitual constipation, menstruation and other postpartum symptoms. A research tells they prevent loss of bone tissues by inhibiting the differentiation of osteophage. Decursinol in them is for pain-relieving, decursin for anticancer, angelan for anti-diabetes. They promote red blood cell production and protein synthesis. They are anti-inflammatory, pain-relieving.
Pueraria root: The levels female hormone related to biosynthesis of collagen in a human body plummet after menopause. The collagen cosmetics released recently in the market contain vegetable female hormone from pomegranate or isopeulrabon from soybean. One research, however, showed pueraria root has 600 times more vegetable female hormone than pomegranate.
Hereinafter, a manufacturing method of oriental medicinal collagen food for skin beauty enhancement will be described with reference to FIG. 1.
FIG. 1 is a flowchart illustrating a manufacturing method of oriental medicinal collagen food for skin beauty enhancement prepared with chicken feet, dandelion, angelica gigas, and pueraria root as main ingredients.

7.5 liter of Gyepogyo from the fourth process was dried with a low-temperature vacuum condenser to produce 850 g of oriental medicinal collagen skin beauty food powder. 170 pouches with Gyepogyo with 5 g each were prepared.
The oriental medicinal collagen skin beauty food, which is the mixture of the individual extracts from high-protein and anti-oxidative foods, has beneficial effects on skin elasticity, moisture retention, wrinkle, and pores. The reason for protein content increase is thought to be due to the fact that the main ingredient, the chicken feet, dandelion, angelica gigas, pueraria root, accelerated the protein biosynthesis and absorption in a human body. Significant differences were shown in moisture, elasticity, pores, wrinkles, and other items before and after the consumption.
In addition, the increase in bodily water content, skin moisture increase, and reduction in pore size were verified after the consumption of the oriental medicinal collagen skin beauty food. This shows that the vegetable protein in pueraria root has a close relation with skin elasticity, pore, wrinkle, and moisture retention.
