Summary for Patent: 10,023,887
Title:Method of manufacturing an amino-acid composition using animal by-products
Abstract: The present disclosure provides a method for preparing an amino acid composition using an animal byproduct, particularly a method for obtaining an amino acid composition of high quality using an animal byproduct more effectively in short time. Because an amino acid composition can be obtained from an animal byproduct more effectively and quickly using the method of the present disclosure, utilization of livestock waste, etc. can be enhanced and application as various products can be expected.

Assignee:
Application Number:15/158,021
Patent Claims:1. A method for preparing an amino acid composition using an animal byproduct, comprising: (1) disrupting the cell membrane of an animal byproduct; (2) obtaining a fermentation product by fermenting the byproduct with the cell membrane disrupted; and (3) sterilizing the fermentation product; wherein disrupting the cell membrane in (1) comprises, in order: crushing the animal byproduct with a nanobubble generator that generates bubbles having an average diameter of less than 1 .mu.m, adding purified water comprising an alkaline substance or adding lye prepared from wood ash, and controlling pH at 5-7 and temperature at 62-65 .degree. C., wherein obtaining the fermentation product in (2) comprises: mixing the cell membrane disrupted with two or more enzymes selected from pepsin, rennin, trypsin, chymotrypsin, erepsin, aminopeptidase, prolinase, prolidase, enterokinase, carboxypeptidase, dipeptidase, papain, bromelain, ficin, actinidain, elastase, subtilisin, pancreatin, nattokinase, arazyme, collagenase, keratinase, gelatinase, savinase, and subclasses thereof at a pH of 5-7, stirring the byproduct to which the enzymes have been added at 50-70 rpm, and controlling the temperature of the byproduct to which the enzymes have been added at a temperature of 61-65 .degree. C. after mixing with the enzymes, and wherein sterilizing in (3) comprises sterilizing with ozone.

2. The method for preparing an amino acid composition according to claim 1, wherein the animal byproduct in (1) comprises the skin, muscle, blood, guts and placenta of livestock or fish.

3. The method for preparing an amino acid composition according to claim 1, wherein an amount of the purified water comprising an alkaline substance or the lye prepared from wood ash is 5-15 wt % based on the total weight of the byproduct.

4. The method for preparing an amino acid composition according to claim 1, wherein an amount of the enzyme is 2.5-4.5 wt % based on the total weight of the byproduct which has passed (1) of claim 1.

5. The method for preparing an amino acid composition according to claim 1, wherein said mixing is performed under a condition where the temperature of the byproduct which has passed (1) of claim 1 is 5-25 .degree. C.

6. The method for preparing an amino acid composition according to claim 1, which further comprises, after (3), adding a preservative.

7. The method for preparing an amino acid composition according to claim 6, wherein the preservative comprises a wood vinegar, and an extract obtained by extracting one or more selected from a group consisting of mugwort, plantain, aloe, peony and grapefruit, wherein the preservative is added in an amount of 3-7 wt % based on the total weight of the byproduct which has passed (1).
