Method for extracting amino acids from giant salamanders

Abstract

The invention relates to the field of a biological technology, in particular to a method for extracting amino acids from giant salamanders. The method comprises the following steps of (1) performing sterilization treatment; (2) performing hydrolization; (3) performing acidolysis; (4) performing neutralizing; (5) performing acidolysis for the second time; (6) performing neutralizing for the secondtime; (7) performing extraction; and (8) performing purification. Giant salamander skin and giant salamander muscle are mixed as raw materials for extracting the amino acids, giant salamander resources are sufficiently used, and through operation steps of sterilization treatment, hydrolization, acidolysis, neutralizing, acidolysis for the second time, neutralizing for the second time, extraction and purification, the extraction rate of amino acids in the giant salamander is effectively increased. Determination proves that the extraction rate of the amino acids is 82% or above, the purity is ashigh as 97% or above, requirements for the content and the quality of the amino acids in the market at current are effectively met, and the market application value of the amino acids is increased.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a method for extracting amino acids from giant salamanders. Background technique [0002] Giant salamander, also known as giant salamander, belongs to Amphibian Caurus order and is known as soft gold. It is rich in protein and trace elements, as well as a small amount of fat. Among them, 8 kinds of amino acids are essential amino acids for human body. They not only have high nutritional value, but also can Prevent many diseases, improve human immunity and cell metabolism. At the same time, giant salamander has high application value in food and medicine, such as: beauty and beauty, prevention of cardiovascular diseases, anti-aging, anti-cancer, etc. It is a very good health food. In recent years, with people's understanding of the giant salamander, there are more and more researches on the giant salamander at home and abroad. In order to better utilize the nutritional value a...

[0004] Compound preparations composed of a variety of amino acids play a very important role in modern intravenous nutrition infusion and "element diet" therapy. They play an active role in maintaining the nutrition of critically ill patients and saving their lives. They have become one of the indispensable medical varieties in modern medicine. 1. Therefore, the extraction process of amino acids has attracted more and more attention; animals are rich in a large amount of amino acids, such as the application number 201410380978.5 "Method for Extracting Amino Acids from Oyster Meat", take oyster meat and cook it with high-temperature steam at 90-100°C for 5-15 minutes, After being cooked and sterilized, the weight ratio of fresh oyster meat to salt and hot water at 60-70°C is 100:3-10:78-82. Add salt and hot water to cooked oyster meat, Grind into a slurry at high temperature. When the slurry is cooled to 40°C, add 1% fresh oyster meat weight pre-expanded fermented strains, stir evenly, and seal and ferment for 30-50 days at 20-25°C. Fully stir once every 2 days, filter the fermented liquid, bottle the clarified filtrate, spray and sterilize it at 85-95°C for 20 minutes, and obtain a reddish-brown or brown oyster amino acid liquid with a delicious smell. Giant salamander is rich in Amino acids, amino acids and other substances, the extraction of amino acids from giant salamanders has been related to patent research reports, but there are no relevant research reports on the extraction of amino acids from giant salamanders
