Method for producing compound amino acid with poultry feathers as raw material

Abstract

The invention discloses a method for producing a compound amino acid with poultry feathers as a raw material. The method comprises the steps: firstly, washing and drying the poultry feathers, carrying out shearing smashing pretreatment, after shearing smashing, adopting a microwave puffing and protease enzymolysis combined method, then carrying out deodorization, peculiar smell-removal and decoloration treatment by adopting activated carbon, filtering, concentrating, carrying out high speed centrifugal spray drying, and finally producing the compound amino acid. The method adopts the waste feathers as the raw material, has wide sources of the raw material, develops a new way for resource utilization and development of waste materials, reduces environmental pollution and resource waste, increases social benefits, besides, has the advantages of simple equipment, simple technological process and strong operability, and can realize industrialized production; and the produced compound amino acid has good quality, the compound amino acid conversion efficiency of the feathers reaches 68.4%, the production yield is high and reaches 85.7%, and resource utilization on the poultry feathers produced by breeding is performed.

Description

technical field [0001] The invention relates to a method for compounding amino acids, in particular to a method for producing compound amino acids with poultry feathers as raw materials. Background technique [0002] In recent years, my country's animal husbandry industry has accounted for an increasing proportion of agricultural production, and the breeding methods have also changed from traditional farming models to large-scale and intensive models. Large-scale poultry farming has produced a large amount of feather waste. According to the statistics of the China Animal Husbandry Association, the annual output of poultry is more than 20 million tons, and the feathers of poultry account for 5%-7% of its weight. Based on this calculation, the annual output of feathers is about 1-1.4 million tons. The crude protein content of feather is more than 80%, which is known as "the crown of natural protein". Therefore, feather waste has a very wide range of uses after proper treatmen...

Problems solved by technology

The inventions of the above patents all use acid and alkali to hydrolyze the raw materials and then concentrate to prepare compound amino acids. The disadvantages are that the yield of hydrolysis is low, and the amount of acid and alkali added is difficult to control accurately, which may often cause environmental pollution and increase the cost.
