Embodiment 1

[0021] Embodiment 1 is rich in the preparation of ferulic acid vinegar

[0022] (1) The raw material glutinous rice is made into glutinous rice through steps such as soaking rice, steaming rice, and pouring rice.

[0023] (2) Alcoholic fermentation: evenly mix 0.4% wine medicine in the glutinous rice, and after saccharification at 18°C ​​for 56 hours, add 30% water and 5.5% Zhenjiang balsamic vinegar Daqu, and keep warm at 30°C for 5 days. That is to get the mature fermented grains.

[0024] (3) Acetic acid fermentation: mix the wine grains with 1.3 times the bran of the raw material mass evenly, insert the Aspergillus niger suspension accounting for 2.1% of the raw material weight at the same time, add the cellulose compound enzyme accounting for 2% of the raw material mass, and obtain the wine bran mixture. Stir in bran with 5% mass of raw material, inoculate 1% vinegar unstrained spirits at the same time, ferment at 30°C, and ferment for 15 days.

Abstract

The invention discloses a functional vinegar rich in ferulic acid and a production method thereof, belonging to the technical field of food brewing. In the invention, glutinous rice is used as a raw material, and a high-yielding ferulic acid esterase suspension of Aspergillus niger is added in an acetic acid fermentation stage, and a cellulose compound enzyme is added at the same time. The vinegar produced by the invention is rich in ferulic acid, has the functions of anti-oxidation, lowering blood pressure, anti-thrombosis, lowering blood fat, antibacterial and anti-inflammatory, preventing cancer, protecting liver, treating diabetes and the like, and has both edible and health-care effects.

Description

technical field [0001] The invention relates to functional vinegar rich in ferulic acid and a production method thereof, belonging to the technical field of food brewing. Background technique [0002] my country is a large country of vinegar production and consumption, and has a long history of making vinegar. Many people have the habit and hobby of eating vinegar. In recent years, the consumption of vinegar has shown an increasing trend year by year in our country. At the same time, with the improvement of people's living standards, consumers' demand for food has gradually shifted from "hobby" to "healthy". Many people like it. However, vinegar is made by complex fermentation of multiple strains, and the functional factors and their mechanism of action in vinegar are still unclear. Therefore, the development of vinegar with definite functional components has become the development trend of the vinegar industry. [0003] Ferulic acid is a phenolic acid ubiquitous in the ...
