One, the technical field
The invention relates to a bean milk rich in folic acid and a production method thereof, belonging to the technical field of food processing.
Second, background art
Folic acid refers to tetrahydrofolic acid and derivatives thereof, and is a water-soluble B vitamin. Folic acid is present in all organisms as a cofactor for the one-carbon transfer reaction in one-carbon metabolism. Important one-carbon metabolism is nucleotide biosynthesis, amino acid metabolism (e.g., serine to glycine, histidine breakdown), and the methylation cycle (e.g., the conversion of homocysteine to methionine by demethylation), which provides a number of methyl and methylation reactions. Therefore, the influence of folate and its metabolism on cellular metabolism is of crucial importance. Inadequate folic acid intake has been shown to induce megaloblastic anemia; especially, the lack of folic acid in pregnant women can cause the development defect of fetal neural tubes. Meanwhile, low levels of folic acid intake are closely related to the occurrence of senile dementia, cardiovascular diseases and various cancers.
The soybean is rich in nutrition, high in protein content and relatively complete in amino acid composition; the fat is high in quality and contains a large amount of unsaturated fatty acid; the soybean oligosaccharide has low calorie, and the dietary fiber can reduce the serum cholesterol level; is rich in various physiologically active components such as isoflavone, gamma-aminobutyric acid, etc. After the soybean seeds germinate, life metabolic activity begins, a series of physiological and biochemical changes occur in vivo, and a large amount of endogenous enzymes are activated, so that substances with physiological activity to a human body are enriched. The lipid substance is decomposed into glycerol and fatty acid under the action of enzyme, and finally, the saccharide which can be absorbed by human body is generated; the protein is also hydrolyzed into micromolecular peptide and amino acid, which is convenient for human body to absorb; the contents of folic acid, gamma-aminobutyric acid, isoflavone and other physiologically active components are correspondingly increased. Buds and related foods thereof are unique in the food industry due to the special medical care function and are very popular with people.
The method adopts citric acid buffer solution with specific pH to spray the germinated soybean seeds, activates endogenous enzyme, enriches folic acid and strengthens the health care function of the soybean milk beverage. After the compound is compounded with sodium ascorbate, the content of vitamin C in the product is improved, and folic acid is protected to a certain extent and prevented from being degraded, so that the bean milk rich in folic acid is a functional beverage rich in vitamins.
