Preparation method for producing amino acid through livestock blood bioconversion and product

Abstract

The invention discloses a preparation method for producing amino acid through livestock blood bioconversion. The preparation method comprises the following steps: collecting and storing fresh livestock blood from a slaughter house; removing fat fiber from the livestock blood; producing friendly amino acid through secondary bioconversion of the livestock blood; performing post-treating and packaging and the like. The invention further discloses amino acid powder or amino acid solutions prepared by the preparation method. By using high-frequency and low-frequency ultrasonic, a bioconversion reaction tank and other technical equipment, and in combination with a special preparation method and optimized conditions, 18 types of main amino acid solutions or amino acid powder with the content of 18.66% or more are prepared, and the amino acids have smaller molecular weights, high internal absorptivity and high product yield; the equipment cost is reduced; livestock blood resources are recycled and wastewater pollution caused in production of blood powder is avoided, the preparation method is environment-friendly; the product is stable in quality and can realize industrialization easily.

Description

technical field [0001] The invention belongs to the technical field of biomass processing, and in particular relates to a preparation method and products for producing amino acids through biotransformation of livestock blood. Background technique [0002] In China, the total number of pigs, cattle and sheep slaughtered in China has reached more than 700 million, and the total amount of animal blood is more than 2 million tons. Except for blood tofu or feed, only a part of it is used as raw material for medicine in pharmaceutical companies or as dry form of livestock feed, such as blood meal. There are few types of blood products, and the application of animal blood in food is almost blank. Most of the blood is discharged. The loss of protein resources also causes serious environmental pollution. With the advent of the 21st century, my country has paid more and more attention to environmental protection. Since the pollution load BOD5 per kilogram of blood is 150 grams, it ta...

Problems solved by technology

(2) Hydrolyzing animal blood protein to prepare mixed amino acids: At present, there are many domestic studies on the preparation of fermented feed from animal blood, but there are few reports on the preparation of mixed amino acid powder from hydrolyzed animal blood protein as feed additives. 2. Used in the food industry: Animal blood is not only rich in protein, but also rich in glucose, vitamins and minerals

[0004] However, at present, there are few domestic researches on the preparation process of amino acids converted from animal blood, and there are not many enterprises that can realize large-scale industrial production.
