Whole quinoa bioactive peptide nutrition product and preparation method thereof

Abstract

The invention provides a whole quinoa bioactive peptide nutrition product, which contains 1.5 to 80 percent of whole quinoa bioactive peptide and also contains oleic acid, linoleic acid, linolenic acid, saponins, flavonoids, choline, betaine, beta-glucan, calcium, magnesium, phosphorus, potassium, iron, zinc, manganese, selenium, flavonoids, vitamin B group and vitamin E group. Quinoa is used as amain material; the plant protein powder is used as auxiliary materials; mixing, water addition, pulping, and high pressure homogenization refining treatment are performed; the slurry fineness reaches300 meshes; then, alpha treatment and further denaturation treatment are performed under the conditions of 3 to 4 barometric pressures and 143 to 145 DEG C; then, the temperature is lowered to 66 to68 DEG C; the pH value is regulated to a neutral state; lipase and amylase are firstly added; constant temperature still standing biochemical treatment is performed; next, neutral protease is added; the pulse type dynamic impact stirring with the rotating speed of 3200 to 3400 r / min is performed; after the constant-temperature still standing biochemical treatment, enzyme deactivation and sterilization are performed; whole quinoa peptide raw liquid is obtained through the precipitation by a precipitation system; the whole quinoa peptide nutrition product is prepared through concentration and filtering.

Description

technical field [0001] The invention relates to a nutritional product, which is a whole quinoa active peptide nutritional product produced with quinoa as the main raw material and a preparation method thereof based on the principles of tissue protein engineering, enzyme engineering and modern physics nanotechnology of modern bioengineering technology . Background technique [0002] Quinoa is native to the Andes in South America. It is the main traditional food of the Inca indigenous people. It has a practical and planting history of more than 5,000-7,000 years. Because of its unique rich and comprehensive nutritional value, it was used by NASA in 1980 Space food for astronauts. The Food and Agriculture Organization of the United Nations believes that quinoa is the only food that can basically meet the basic nutritional needs of the human body with a single plant, and officially recommends quinoa as the most perfect and complete nutritional food for humans. Quinoa is known ...

Problems solved by technology

[0007] The difficult problem to be solved by the present invention is: the one, will solve the problem that protein in the quinoa is converted into the low conversion rate of peptide (being ≤ 10% domestic and ≤ 38% international) problem; It leads to the problem that the peptide liquid is difficult to separate out after gelatinization produces high gelatinity in the process of heat and pressure subdivision treatment; the third is to keep the other nutrients in quinoa basically not lost
