Abstract

The invention provides pea peptide with an auxiliary hypoglycemic function as well as a preparation method and an application of the pea peptide. The pea peptide at least comprises peptide fragments pEE, pEK and pER, based on the mass of the pea peptide, the content of the peptide fragment pEE is more than or equal to 100.00 mg / 100g, the content of the peptide fragment pEK is more than or equal to 80.00 mg / 100g, and the content of the peptide fragment pER is more than or equal to 90.00 mg / 100g. The pea peptide has a remarkable effect in the aspect of reducing blood sugar.

Description

technical field [0001] The invention relates to a pea peptide with the function of assisting in lowering blood sugar and a preparation method thereof, belonging to the field of biotechnology. Background technique [0002] Pea, also known as wheat pea, cold bean, wheat bean, snow pea, has the characteristics of cold resistance, drought resistance, barren resistance, etc., and has strong adaptability. Therefore, it is widely distributed all over the world, and the planting area and output are relatively stable. The average annual output Around 10 million tons. The protein content in peas is relatively high, accounting for 23-25% of the dry pea mass, and the amino acid composition of pea protein is relatively balanced, so pea protein is a high-quality vegetable protein. [0003] At present, the starch and vermicelli industry will produce a large amount of pea protein by-products in the production process, and these pea protein by-products will be pea protein after simple purif...
