Embodiment 1

[0031] A bioaccumulation and product development method of functional malt extract is characterized in that it consists of the following steps:

[0032] (1) Crushing of raw materials: barley malt and broken rice are pulverized with a universal pulverizer.

[0033] (2) Ingredients: Feed according to the ratio of malt, broken rice and yeast at a ratio of 1:1:1, and then add pure water to adjust the slurry.

[0034] (3) Enzymatic: Adding pyridoxal phosphate and Ca ions in a ratio of 0.1% can promote the activity of glutamic acid decarboxylase, 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.

[0035] (4) Enzymatic hydrolysis: Add α-amylase and protease at a ratio of 0.1% for directional biodegradation to obtain sugar sources and protein sources capable of producing good malt essence flavor. The feed solution is heated to 50° C. and kept for 1 hour....

Embodiment 2

[0043] A bioaccumulation and product development method of functional malt extract is characterized in that it consists of the following steps:

[0044] (1) Crushing of raw materials: barley malt and broken rice are pulverized with a universal pulverizer.

[0045] (2) Ingredients: Feed according to the ratio of 1:2:1 of malt, broken rice, and yeast, and then add pure water to adjust the slurry.

[0046] (3) Enzymatic: Adding pyridoxal phosphate and Ca ions in a ratio of 0.2% can promote the activity of glutamic acid decarboxylase, 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.

[0047] (4) Enzymatic hydrolysis: Add α-amylase and protease at a ratio of 0.3% for directional biodegradation to obtain sugar sources and protein sources capable of producing good malt essence flavor. The feed solution is heated to 60° C. and kept for 40 minutes.

Abstract

A functional malt extract product enriched with gamma-aminobutyric acid and beta-glucosan is prepared from malt, brown rice and waste beer yeast as materials by a plurality of integrated technologies such as micro-wave assisted countercurrent extraction, yeast biological wall-breaking, bio-concentration of gamma-aminobutyric acid, facilitation of maillard reaction to generate malt fragrance by a microwave, and continuous microwave vacuum drying. The functional malt extract product can be widely applied to the fields such as food, microbiological industry and medicine. Value-added conversion and cyclic economy of low-value agricultural products are achieved; the functional malt extract product passes through technical evaluation of China General Chamber of commerce organizations in March 2007; and the project level achieves the domestic leader, and the blank of the functional malt extract product in China is filled.

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, ...
