Abstract

The invention discloses a preparation method of selenium-rich germinated rough rice / asparagus fermented vinegar, which adopts selenium-rich germinated rough rice / asparagus mixed fermentation. In the fermentation process, pectinase, amylase, saccharifying enzyme, Rhizopus oryzae CICC3099, Saccharomyces cerevisiae CICC1050 and Acetobacter pasteurianus CICC21870 are added. In the prepared vinegar, the gamma-aminobutyric acid content is 8-13 mg / 100g, the vitamin content is higher than 0.3%, and the selenium content is 200 ug / kg. Therefore, the vinegar produced by the method has the advantages of multiple nutritional ingredients, aromatic flavor and soft and sweet mouthfeel, and is a vinegar product with favorable mouthfeel and nutrient and health-care effects.

Description

technical field [0001] The invention belongs to the field of health-care vinegar processing, in particular to a selenium-enriched germinated brown rice asparagus fermented vinegar and a preparation method thereof. Background technique [0002] Vinegar can be produced by itself in the natural environment, and ancient humans have been eating vinegar since very early. In my country, it is generally believed that vinegar began to be brewed in the Western Zhou Dynasty. The composition of vinegar usually contains 3%-5% acetic acid, lactic acid, various minerals, and some also have a small amount of tartaric acid, citric acid and so on. Vinegar has the effects of reducing swelling, detoxification, digestion, and dispersing silt. Drinking an appropriate amount of vinegar is of great help to your health. [0003] The scientific name of asparagus is Dizhu, which is fresh and tender in texture, delicious in flavor, tender and delicious. Asparagus stems are rich in protein, vitamins, ...
