Problems solved by technology

[0008] Whether it is a single protein powder or a composite protein powder, whether it is an animal protein powder or a vegetable protein powder, the above-mentioned disclosed patents mainly focus on the nutritional and functional properties (solubility, stability, foam, emulsification, gelation, etc.) of the protein powder. Sex, etc.) and disease prevention, etc., and all have the following defects more or less: 1) contain a large amount of excessive saturated fat, cholesterol, high calories; 2) add a large amount of food additives such as pigments, sweetness 3) Poor solubility and stability, uneven preparation, prone to agglomeration and stratification; 4) The composition of amino acids is not comprehensive enough, and the composition of various nutrients is not balanced enough; 5) The consumer group involves middle-aged and elderly people There are fewer women and women, and there are limitations; there are few studies on the biological activity of protein powder. The biological activity and potency of protein powder are a comprehensive reflection of its nutritional, functional and other properties. The environment (temperature, humidity, light, oxygen) has a great influence, especially in the technical fields of active microbial agents and enzyme preparations.
In the prior art, there are few relevant patent documents or technical documents that solve the freezing resistance of composite protein powder or composition, almost none

Abstract

The invention discloses a composite protein powder and a preparation method thereof. Using soybean protein isolate, whey protein concentrate and phospholipid as main raw materials, stevia is processed into stevia extract at low temperature, and the effective components of stevia can be retained to the maximum extent. and bioactive ingredients, high extraction rate, pure flavor, natural color, no licorice flavor, scientifically compound with main ingredients, and add antifreeze polypeptide, dietary fiber powder, bee pupa enzymolysate, wheat germ powder to prepare a It is a compound protein powder with suitable taste, good solubility, comprehensive nutrition, strong biological activity and suitable for a wide range of people. The preparation method adopts non-thermal processing technology, high working efficiency, low energy consumption, environment-friendly, non-polluting, reduces the introduction of food additives and chemical auxiliaries, effectively improves food safety, improves product quality and reduces production costs , to achieve the goal of low-carbon production, can be scaled, industrialized development.

Description

technical field [0001] The invention relates to protein powder, in particular to a composite protein powder and a preparation method thereof. Background technique [0002] Protein is the main constituent material of the human body and the main material of human life activities. Protein plus nucleic acid is the main form of life. The original meaning of protein in ancient Latin is "primary". Although it is a part of nutrients, it is in a central position of various nutrients. Its main functions are: 1. It is used to make muscles, blood, skin and various body organs. 2. Help the body create new tissue to replace damaged tissue. 3. Deliver various nutrients to cells. 4. Regulate the balance of water in the body. 5. Make antibodies for the immune system to fight bacteria and infections. 6. Help wound blood coagulate and heal. 7. Produce enzymes in the body to help convert food into energy. The lack of protein in the human body can be fatal. The protein in the human body ...
