Embodiment 1

[0033] A biological enrichment method for functional malt essence is characterized in that it consists of the following steps:

[0034] (1) Raw material crushing: barley malt and brown rice are crushed with a universal grinder;

[0035] (2) Ingredients: Feed according to the ratio of barley malt, brown rice, and yeast at a ratio of 1:1:1, and then add pure water to adjust the slurry;

[0036] (3) Enzymatic: Adding pyridoxal phosphate and Ca ions in a ratio of 0.1% can promote the activity of glutamic acid dehydroxylase, and glutamic acid in brown rice is decarboxylated under the catalysis of glutamic acid decarboxylase to generate abundant γ-aminobutyric acid, to achieve the purpose of enrichment;

[0037] (4) Enzymatic hydrolysis: add α-amylase and protease at a ratio of 0.1%, directional biodegrade barley malt to obtain sugar source and protein source capable of producing good flavor of malt extract, raise the temperature of the feed solution to 50°C, and keep it for 1 hour...

Abstract

This project uses malt, brown rice and waste brewer's yeast as raw materials, adopts microwave-assisted countercurrent extraction, yeast bio-breaking, bio-enrichment of γ-aminobutyric acid, microwave-promoted Maillard reaction to generate malt aroma and continuous microwave vacuum drying, etc. A number of integrated technologies prepare functional malt essence products enriched in γ-aminobutyric acid and β-glucan, which can be widely added to the fields of food, microbial industry and medicine. This project has realized the value-added transformation of low-value agricultural products and circular economy. In March 2007, it passed the technical appraisal organized by the China Federation of Commerce. The project level has reached the leading level in China, filling the blank of functional malt essence products in my country.

Description

technical field [0001] The invention relates to an extraction method for deep processing of malt extract, in particular to produce a new functional malt extract product rich in γ-aminobutyric acid and β-glucan through biological enrichment, raw material ratio and high-efficiency extraction and separation technology. Endow new malt extract products with functional properties and health benefits. Background technique [0002] Malt essence has been a mature food ingredient or food additive in foreign countries. It has a history of hundreds of years and the annual demand is huge. The refined output has reached 150,000 tons, and there are more than 100 wheat refined varieties. The company was established in 1921 and has a long history. [0003] The use of malt extract as a food additive has just started in my country. Although there has been a small amount of production in the past two years, due to the lack of advanced deep-processing technology and equipment for malt extract, ...
