Embodiment 1

[0033] Embodiment 1: refer to figure 1 ;

[0034] A method for extracting amino acids from donkey hair, comprising the following steps:

[0035] 1) Recover rough donkey hair; collect the donkey skin peeled off after the meat donkey is slaughtered in the slaughterhouse, and then use a mechanical scraper to shave the rough donkey hair on the donkey skin. The donkey skin is collected to be used for preparing donkey-hide gelatin. The donkey hair is loaded and stored, and transported to the area to be processed;

[0036] 2) Pretreatment of crude donkey hair: Unload the crude donkey hair, first wash it with water, clean blood stains and other stains on the surface of the crude donkey hair, and then perform high-temperature cooking to further remove the peculiar smell and stains attached to the crude donkey hair , high-temperature sterilization at the same time to reduce the pollution of bacteria and fungi, and finally the rough donkey hair after high-temperature cooking is placed ...

Embodiment 2

[0042] Embodiment 2: refer to Figure 6 , based on Example 1, the difference is that

[0043] 5) The steps of refining and extracting multiple amino acids in the step to prepare amino acid oral liquid are:

[0044] S1. Preparation of various amino acids: Mix and concentrate the compound amino acid liquid I, compound amino acid liquid II and compound amino acid liquid III to crystallize, control the temperature, and adjust the pH to obtain crude alanine and compound amino acid liquid IV, crude alanine Refined alanine is prepared through multiple decolorization and purification treatments; the compound amino acid solution IV is concentrated and crystallized, the temperature is controlled, and the pH is adjusted to obtain crude glycine and compound amino acid solution V, and the crude glycine is subjected to multiple decolorization and purification treatments to prepare refined glycine; Concentrate and crystallize the compound amino acid solution V, control the temperature, and ...

Embodiment 3

[0047] Embodiment 3: Based on Embodiment 1, the difference is that;

[0048] 4) The step also includes a degree of hydrolysis test. Take a small amount of mixed hydrolyzate, add 15% sodium hydroxide solution, heat slightly, and drop a few drops of copper sulfate solution. If the solution remains blue, it means that the hydrolysis is complete. If the solution If no blue color appears, continue hydrolysis until the hydrolysis is complete.

[0049] Hydrolysis degree test: take 1mL of mixed hydrolyzate and put it in a 10mL test tube, add 4mL15% NAOH aqueous solution, heat slightly, drop 4~5 drops of CuSO 4 Solution, shake well, if the solution remains blue, it means that the hydrolysis is complete; if it is purple or reddish orange, the hydrolysis is not complete; the hydrolysis effect can be effectively distinguished by the degree of hydrolysis test, which is conducive to the improvement of the hydrolysis efficiency; protein molecules contain peptide bonds, In a strongly alkalin...

Abstract

The invention discloses equipment for extracting amino acid from donkey hair and a method for extracting the amino acid from the donkey hair, and belongs to the field of chemical extraction. The method comprises the steps of crude donkey hair recovery, crude donkey hair pre-treatment, dried donkey hair degreasing treatment, degreased donkey hair hydrolysis, refined cystine preparation and amino acid oral liquid preparation; effective degreasing treatment equipment is provided for dried donkey hair degreasing treatment, by using the degreasing treatment equipment, donkey hair degreasing treatment integration can be achieved, manpower and material resources are saved, degreasing time is saved, by combining a dried donkey hair degreasing method with the degreasing treatment equipment, degreasing of the donkey hair can be effectively achieved, the degreasing efficiency is improved, improvement of a hydrolysis effect of a subsequent working procedure is facilitated, then the yield of the amino acid can be effectively improved, resources can also be saved to prepare amino acid oral liquid required by a human body, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to the field of chemical extraction, in particular to a device and method for extracting amino acids from donkey hair. Background technique [0002] Amino acid is an important part of biological organisms, the basic unit of protein, and has extremely important physiological functions. For nearly a century, human beings have continuously revealed the secrets of protein, making the production of amino acid products develop rapidly. In 2012, the output of amino acids has reached 3.3 million tons. At present, my country's amino acids have made great progress in both new product development and production and application. At present, in addition to applications in the fields of medicine, food, feed, cosmetics, etc., amino acid products and derivatives of amino acid products have also been continuously applied in fields such as agricultural production and chemical industry. At present, there are various amino acid products on the mark...
