Abstract

The invention aims at providing a production method for clarifying malt extract with the advantages that the appearance and the mouth feeling are good, and the original nutrition ingredients can be maintained. The production method for clarifying malt extract comprises the following production steps that a, barley and malt are crushed and are conveyed into a saccharifying tank, three times of water is added, and the materials are continuously stirred for 80 to 90 minutes under the conditions being 40 to 50 DEG C; b, meanwhile, food level protease, food level glucanase and food level glucoamylase are added, and enzymolysis is carried out for one and a half hours; c, the temperature is raised to 75 DEG C, and the heat insulation is carried out for 50 minutes; d, the temperature is raised to 80 DEG C, and enzyme deactivation is carried out; e, wort obtained after diatomite filtering is subjected to heat insulation for 30 minutes at 100 DEG C; f, 20ppm food level clarifying agents are added, the temperature is lowered to 2 DEG C, and the cooling treatment is carried out for 24 hours; and g, clarified liquid malt extract is obtained through filtering and concentration.

Description

The production method of clarification malt extract

Technical field

The present invention relates to the nutraceutical production field, especially clarify the production method of malt extract.

Background technology

Malt extract is the full-natural nutritive material that is rich in maltose, fructose, amino acid, small-molecular peptides, multivitamin, trace element and multiple somatomedin by enzymolysis and extraction from barley and Fructus Hordei Germinatus.The liquid malt extract is that barley, Fructus Hordei Germinatus are that raw material is made first wheat juice, and wheat juice becomes malt extract through Vacuum Concentration.Outward appearance: yellow to auburn, thickness, show slightly muddy liquid, but without exogenous impurity.Smell: have typical pleasant Fructus Hordei Germinatus fragrance.Flavour: have typical sweet in the Fructus Hordei Germinatus fragrance of little hardship, free from extraneous odour.Malt extract has been applied in the food such as dairy products, beverage, biscuit and chocolate in the world.Present malt extract all is raw material (barley and Fructus Hordei Germinatus) through pulverizing, saccharification, filtration and the explained hereafter such as concentrated, and nutriment is abundant, and human body is digested and assimilated easily, but because contains a lot of labile element (mainly being protein) in the product.When in beverage, using, separate out easily, have a strong impact on the sense organ of product.

Summary of the invention

The objective of the invention is to provide a kind of impression and mouthfeel all fine and can keep the production method of the clarification malt extract of original nutritional labeling.

Its production stage is as follows:

1, the production method of clarification malt extract, its production stage is as follows:

A delivers to saccharifying tank with barley and Fructus Hordei Germinatus pulverizing, adds three times water, continuous stirring 80-90min under 40-50 ℃ of condition;

B adds the food-grade albumen enzyme simultaneously, food-grade dextranase, food grade saccharidase, enzymolysis one and a half hours;

C is warming up to 75 ℃, insulation 50min;

D is warming up to 80 ℃ of enzymes that go out;

E, the wheat juice that obtains behind the diatomite filtration is at 100 ℃ of lower insulation 30min;

F, the food-grade fining agent of adding 20ppm is cooled to 2 ℃ of cooling processing 24h;

G obtains the supernatant liquid malt extract through filtering, concentrating;

H obtains the solid malt extract after super-dry.

Through above 8 steps, labile element is removed: by continuous heating stir (40-50 ℃ 80-90min) can make a part of unstable material sex change separate out, by removing a part behind the diatomite filtration.Remove again a part of protein through the processing of food-grade fining agent again, make the malt extract that obtains have the characteristic of stable clarification.

What the present invention set forth is the production method of clarification malt extract, it contains most nutriments of existing malt extract, removed labile element wherein, can be applicable to clarity is required higher beverage industry, also can be directly as the raw material of beer fermentation, thereby strengthen the organoleptic quality of beverage, enrich the nutritional labeling of beverage, break through the use limitation of malt extract, that a kind of impression and mouthfeel are all well clarified malt extract, make it can be used for beverage industry, strengthen the mouthfeel of beverage, enrich its nutriment.

The specific embodiment

Production stage of the present invention is as follows:

1, the production method of clarification malt extract, its production stage is as follows:

A delivers to saccharifying tank with barley and Fructus Hordei Germinatus pulverizing, adds three times water, continuous stirring 80-90min under 40-50 ℃ of condition;

B adds the food-grade albumen enzyme simultaneously, food-grade dextranase, food grade saccharidase, enzymolysis one and a half hours;

C is warming up to 75 ℃, insulation 50min;

D is warming up to 80 ℃ of enzymes that go out;

E, the wheat juice that obtains behind the diatomite filtration is at 100 ℃ of lower insulation 30min;

F, the food-grade fining agent of adding 20ppm is cooled to 2 ℃ of cooling processing 24h;

G obtains the supernatant liquid malt extract through filtering, concentrating;

H obtains the solid malt extract after super-dry.

By continuous heating stir (40-50 ℃ 80-90min) can make a part of unstable material sex change separate out, by removing a part behind the diatomite filtration.Remove again a part of protein through the processing of food-grade fining agent again, make the malt extract that obtains have the characteristic of stable clarification.
