BACKGROUND OF THE INVENTION Proteins are ingested from various foods and play an important role in human life activities. When a protein source is ingested as a food, it is said that a peptide having several to several tens of amino acids is more absorbable than a protein or an amino acid and has a superior nutritional effect. Further, it is known that the allergenicity of proteins is reduced by lowering the molecular weight. Further research on the physiological functions of peptides has progressed, for example, blood pressure elevation inhibitory action, antioxidant action, lipid metabolism promoting action, immunity enhancing action,
Physiological functions such as blood cholesterol lowering action, alcohol absorption suppressing action, iron and calcium absorption promoting action, and moisturizing action have been found. These functional properties possessed by peptides have been attracting attention as important materials in the fields of food, cosmetics, pharmaceuticals and the like.

[0003] However, the peptide is obtained by decomposing various animal and plant proteins with an acid, an alkali, or an enzyme, and has an off-taste derived from the raw materials, an off-flavor, and an off-taste or off-odor produced upon decomposition. When such a peptide is used as it is as a material for foods or cosmetics, an unpleasant odor is transferred to the product, which has been a major limitation when using the peptide for foods or cosmetics.

[0012] Collagen is a major protein constituting animal connective tissue, and is abundantly contained in bone, tendon, skin, blood vessel wall and the like. There are various types of collagen that have one to a plurality of triple helix structures in the molecule and the constituent polypeptide chains have different amino acid sequences. Gelatin is a water-soluble protein having a molecular weight of about 300,000 to tens of thousands obtained by extracting a raw material containing collagen with hot (hot) water, and alkali-treated gelatin (isoelectric point 4.8 to 5.3) and acid are used. There is processed gelatin (isoelectric point 7-9). As a specific preparation method, first, as a pretreatment of the skins and bones of cattle, pigs, etc., the alkali treatment of dipping for 2 to 3 months or the acid treatment of dipping in dilute hydrochloric acid for a short period of time is performed, and impurities contained in the raw material are included. To facilitate removal and extraction. For example, when beef bones are used as a raw material, since the bones contain minerals such as calcium phosphate, they are soaked in dilute hydrochloric acid in advance to recover the minerals, which are then extracted with warm (hot) water to obtain gelatin. Hot (hot) water extraction generally has an initial extraction temperature of 50-6.
At 0 ° C., the temperature is gradually raised after the second time, and finally boiled. The obtained gelatin is hydrolyzed with an ordinary acid or enzyme to reduce its molecular weight to an average molecular weight of 102 to 10.
About 5 collagen peptides can be obtained. Such collagen peptide can be easily obtained on the market, and examples thereof include Nippi peptide PBF (collagen peptide manufactured by Nippi Co., Ltd.) and Nippi peptide PRA.
(Collagen peptide manufactured by Nippi Co., Ltd.), SCP-5
000, SCP-3100 (both are collagen peptides manufactured by Nitta Gelatin Co., Ltd.) and the like. The collagen peptide thus obtained has offensive odors and offensive odors derived from raw materials, such as animal odor and bitterness, and is restricted when used as a raw material for foods and cosmetics.

As is clear from the results shown in Table 1, the collagen peptide of the product 1 of the present invention has almost no off-taste or off-flavor such as animal odor and bitterness derived from the raw materials, and is significantly deodorized as compared with the comparative product 1 deodorized with activated carbon. It was evaluated to be highly effective. (Aroma Analysis by Gas Chromatography) The collagen peptides of Inventive Product 1, Comparative Product 1 and Reference Product 1 were steam-distilled, respectively, and the distillate was extracted with ether to recover the odorous components by a conventional method. Gas chromatographic analysis was performed under the conditions described above, and the difference in odor by sensory evaluation was clarified by the analysis results. Gas chromatography analysis conditions Model: Hewlett Packard HP-6890 Column: Fused Silica Capillary OV101 60m x 0.25mm Column temperature: 70-220 ° C (3 ° C / min) Injection temperature: 250 ° C Detector temperature: 250 ° C Carrier gas: N2 The results of the gas chromatography analysis of 1.8 Kg / cm 2 are shown in Table 2. As a result, while the odor component content of the reference product 1 which is the collagen peptide before deodorization was 2.365 ppm,
The comparative product 1 had a decrease of only 1.134 ppm, but the odor component content of the product 1 of the present invention was 0.366 p.
It was reduced to pm and was reduced to about 1 / 6.5 of the odor component content of Reference Product 1 (undeodorized collagen peptide). In particular, the content of odorous components such as dimethyl disulfide and dimethyl trisulfide, which are considered to be causative substances of animal odor, was removed to a trace extent in the product 1 of the present invention.
