Method for preparing tenebrio molitor protein powder by enzymolysis

Abstract

The invention belongs to the technical field of the processing of food proteins, in particular to a method for preparing tenebrio molitor protein powder by enzymolysis. The method comprises the steps of degreasing, enzymolysis and spray drying. A supercritical CO2 extraction method is adopted for degreasing tenebrio molitor larva, which has no chemical agent residue compared with a solvent extraction method; many kinds of enzymes which can hydrolyze the tenebrio molitor protein are screened to select the optimal proteolytic enzyme, which has high hydrolysis efficiency, by comparison; and the protein is dried in a spray drying way to remain the nutritional value of the tenebrio molitor protein powder to a greatest extent. The tenebrio molitor protein powder produced by the abovementioned method has a high nutritional value, the problem of the shortage of protein resources is solved, the demands of people on the protein are met, and good economic benefit and social benefit are brought.

Description

technical field [0001] The invention belongs to the technical field of food protein processing, and in particular relates to a method for preparing Tenebrio molitor protein powder by enzymatic hydrolysis. Background technique [0002] Protein is the basic substance of life. With the rapid growth of the world population, the demand for protein will increase. Proteins such as milk, eggs, fish, and meat are far from meeting people's needs for protein. Therefore, the development of It has become an urgent task before human beings to find new types of food and seek new sources of protein. Due to the high protein content in insects, less protein fiber, easy absorption of nutrients by the human body, short reproductive generations, high reproductive index, suitable for factory production, and rich resources, it has become the most promising protein food resource at present, and is widely accepted. s concern. Tenebrio molitor, also known as Tenebrio molitor, Tenebrio molitor, co...
