What Is Black Beans Peptide Powder?

What Is Black Beans Peptide Powder?

Black bean peptide powder are mixed peptides obtained by enzymatic hydrolysis or fermentation method, with relative molecular weight less than 10,000 Da and containing different amino acid sequences. Related research shows that the proteins consumed by human are not completely absorbed and utilized by the body as individual amino acids, and the small molecule peptides are easier to enter the bloodstream and play an important role in the body compared with individual amino acids. Therefore, for some weak people, they can consume more small molecule peptides to supplement their nutrition.

Peptide is a compound formed by the dehydration and condensation of several amino acids, with a molecular weight between that of tired white matter and that of amino acids. Bioactive peptide is a common peptide compound, with relative molecular star less than 6000 Da.- generally contains 30-40 amino acid residues, which plays an important role in the regulation of body metabolism and is one of the most promising nutritional factors.

The Source Of Black Beans Peptide Powder Supplement

Black beans are black soybean seed coat, accounting for about 8% of the national soybean cultivation area, more commonly planted around the small black beans, small black beans are high protein and low fat type of soybeans, its protein content up to about 50%, similar to soybean meal, is a very high potential for the development of plant protein resources. However, black bean protein molecules are highly compressed and folded, hard and indigestible, except for a small amount of medicinal use, mainly used as feed, and the research on the modification technology of black bean protein resources is relatively late, so that its deep processing and utilization is limited, the black bean protein peptide, which is easy to digest and absorb, is prepared by enzyme-catalyzed hydrolysis of black bean, which overcomes the weakness and deficiency of black bean protein in nutrition, and is the best nutritional way of black bean protein. Black bean protein peptide also has good processing properties such as good acid solubility and low viscosity, thus expanding the scope of its application in food and beverage processing. It provides a new technical way for the development and utilization of black bean protein.

Soy protein peptide food development is an important direction in the field of deep processing of soybean research, some of the first developed countries dedicated to this area of research, found that the peptide protein obtained from the hydrolysis of soy protein not only has better nutritional characteristics than the original soy protein, and has a better processing characteristics such as isoelectric point soluble, high thermal stability, the United States has been in the early 1970s to study the peptide soy protein products, After that, thousands of tons of edible soy protein peptide plants were built. Japan also successfully used soy protein peptides in the food industry in the 1980s. Chinese soybeans contain low fat and high protein, more suitable for the development and application of new protein products, especially the best prospects for the development of hydrolyzed protein.

Physiological functions of black beans peptide powder supplement

1. Antioxidation

The oxidative damage of the body tissues and organs will affect the recovery of red blood cells, cholesterol metabolism and the anti-fatigue ability of the body. According to the theory of free radical generation, the tissues and organs of the body will produce various free radicals, and if these free radicals cannot be removed in time, they will be oxidized and bring different degrees of damage to the human body. Therefore, it is very important to properly supplement antioxidant substances and timely remove the excess free radicals in the body to enhance the body's resistance to diseases.

2. Anti-fatigue

The external manifestation of fatigue is the decrease of motor ability, and the internal manifestation is the toxicity of body cells. In order to maintain the normal exercise capacity of the body, long-term fatigue should be avoided. Sports is a sport that can easily lead to fatigue, and the related research shows that after taking black bean peptide, the level of testosterone in the blood of long-distance runners increased and the level of RPE decreased after training, which indicates that soybean peptide has certain anti-fatigue effect.

3. Lowering blood lipid

The main component of blood lipid is cholesterol and triglyceride - with the improvement of modern living standard, more and more people have more and more blood lipid than the normal level, suffering from hyperlipidemia. Modern medicine shows that cardiovascular diseases caused by high blood lipids are one of the main causes of death in China. In the early days, it was found that bean peptides had lipid-lifting effects.

4. Black beans peptide powder for skin

Black bean peptides are rich in antioxidant ingredients, such as vitamin E, isoflavones, anthocyanins, etc., which can eliminate free radicals in the body, reduce skin wrinkles and achieve the effect of beauty care, and also rich in vitamin A, which has the effect of repairing damaged skin.

Preparation of black bean peptide powder

In China, although black bean has large production and rich protein content, black bean protein is not easy to be digested and absorbed by human body. Then, it is important to degrade the black bean protein by certain methods to make black bean peptide which can be easily absorbed and utilized by human body. At present, the main methods of preparing black bean peptides are enzymatic digestion and microbial fermentation.

1. Enzymatic method

Enzymatic digestion method often takes plants and animals as raw materials, and then goes through the enzymatic action and separation and purification technology. The products obtained by enzymatic digestion are not toxic and have no side effects to the body. And the operating conditions are easy to control, so it is the most common method to prepare plant peptides.

2. Microbial fermentation method

Microbial fermentation is the process of decomposing small molecule peptide by the action of protease which is secreted by microorganism to extracellular during the fermentation process. Compared with the case method, the fermentation method has obvious advantages, not only eliminating the enzyme purification and inactivation steps, shortening the production time and cost, but also some substances produced during the fermentation process can cover the bitter taste of the bitter peptide and make the product have a certain flavor, so the microbial fermentation method has a broad application prospect.

Isolation and purification of black bean peptides

Black bean protein formed by enzymatic digestion is a mixed system, containing more substances, such as polypeptides, free amino acids, salts, some difficult to hydrolyze proteins, etc.. These substances interact with each other and affect the antioxidant property of black bean peptides. Therefore, in order to get high concentration of peptide solution, the enzymatic products need to be separated and purified. At present, the more used separation methods are membrane separation method and gel filtration chromatography method.

1. Membrane separation method

At present, the main principle of membrane separation technology is to apply pressure on both sides of the selective semi-permeable membrane, molecules smaller than the membrane pore size will be concentrated on the other side of the membrane, while molecules larger than the membrane pore size will not be allowed to pass through the membrane, so that the substances with different molecular though can be separated. In practice, membrane separation can be divided into microfiltration, ultrafiltration, nanofiltration and reverse osmosis according to the different pore sizes of membranes. Since the operating conditions of membrane separation technology are relatively simple. Separation equipment does not have strict requirements, and the separation process does not require the addition of other chemical reagents, does not affect the stability of the nature of the separated material, so the use is particularly widespread.

2. Gel filtration chromatography

This is a simple and effective molecular sieve chromatography, which is easy to operate, mild conditions, good separation and purification effect, and is mostly used for the separation of macromolecular substances.
