01Function of raw material

A lot of researches have found that corn oligopeptide has antioxidant function, sobriety function, blood pressure lowering function, anti-tumor function, etc. However, the deep research on its mechanism is not deep enough yet.

1.Protect the liver

Corn peptide has obvious protective effect on liver damage caused by carbon tetrachloride, thioacetamide, alcohol and other chemical substances. In addition, according to the pathological examination, corn peptide can significantly reduce the fatty degeneration of hepatocytes and significantly improve the degree of liver tissue damage.

2.Promote alcohol metabolism

The unique amino acid composition of corn oligopeptide is good for promoting the metabolism of alcohol. Corn oligopeptide contains high proportion of alanine and leucine. It can enhance the activity of ethanol dehydrogenase and acetaldehyde dehydrogenase in liver, enhance the ability of decomposing and metabolizing alcohol, and promote the decomposition of alcohol.

3.Antioxidant

The semi-inhibitory concentration (IC50 value) of corn oligopeptide to DPPH radical, hydroxyl radical and superoxide anion radical are 1.9, 5.4mg/mL and 14.9mg/mL respectively, and the reducing ability at the mass concentration of 5.0mg/mL is comparable to that of 0.02mg/mL of ascorbic acid, and the antioxidant ability shows a dose relationship with its mass concentration.

4. Hypotension

In order to study the hypotensive effect of corn oligopeptide, different doses of corn oligopeptide (0.45, 1.35, 4.05g/kg.bw) were given by gavage to rats with essential hypertension, and the blank control group was given the corresponding dose of distilled water by gavage. The experimental results showed that maize oligopeptide had significant hypotensive effect, and this result will provide scientific basis for further development of hypotensive drugs and functional foods.

5.Enhance immunity and exercise ability

The amino acid composition of corn peptide is high in glutamine, which is closely related to tissue growth and repair, and has important value in improving immunity, maintaining the normal structure and function of intestinal mucosa, and improving the body's ability to adapt to external harmful stimuli.

In addition, because corn peptide is rich in leucine and absorbed extremely fast, it can quickly provide energy to the muscles and organs of human exercise system, so it has the function of enhancing the exercise ability of human body.

02 Why it can be dissolved in white wine

Corn protein has a high percentage of alcohol-soluble protein. The ability of corn alcohol-soluble protein to dissolve in alcohol is related to its having a special amino acid composition.

The alcohol-soluble protein molecule not only contains a large number of hydrophobic amino acids, but also lacks amino acids that can be charged with acidic, basic and polar groups, and also contains a high number of sulfur-containing amino acids. These above-mentioned factors determine its unique solubility, insoluble in water and soluble in aqueous solutions of alcohols from 60% to 95%.

The corn oligopeptide prepared in this way still retains the amino acid composition of the corn alcoholic protein and has a smaller molecular weight, which also has good alcohol solubility. Also corn oligopeptides are easily soluble in water and therefore have very good solubility in white wine.

03 Application in food

Oligopeptide can be widely used in health food, sports nutrition food, beauty food, special medical use formula food, protein-based nutrition food. At the same time, oligopeptide can be used as an important nitrogen source and functional addition in meal replacement food and solid beverage because of its easy solubility, stability and physiological activity.
