Abstract

The syrup specially for beer consists of glucose 5-15 wt%, maltose 45-70 wt%, maltotriose 10-20 wt%, maltotertrose and higher maltose 10-20 wt%; contains amino nitrogen of 120-180 mg/L; and has saccharide to non-saccharide ratio of 1 to 0.15-0.35. The present invention is prepared by means of advanced bioengineering technology, has stable quality and low production cost, and may be used in replace rice and malt partially or completely in beer production. The syrup may be used in the amount over 50 % through direct addition to boiling pot to lower beer producing cost and raise beer quality.

Description

Specialized syrup of beer and preparation method thereof

Affiliated technical field

The present invention relates in a kind of beer production, substitute the syrup dedicated of barley; Particularly a kind of malt syrup that contains alpha-amino nitrogen and preparation method thereof.

Background technology

At present, beer mainly contains three kinds with syrup dedicated: (1) brewer's barley syrup; (2) beer high maltose syrup; (3) beer oligosaccharide syrup.First kind of starch syrup carries out saccharification owing to add barley in process of production, finished product and barley juice of beer basically identical, and production cost can't reduce, and is restricted in application, only is applicable to that the home-brewed wine city of each big and medium-sized cities is used, and demand is limited; Second the third starch syrup, demand rose to some extent in recent years, because of it does not contain alpha-amino nitrogen, just substituted the rice auxiliary material, and comparative costs is not obvious.Have only required sugared source, nitrogenous source, mineral salt and the VITAMIN etc. of the beer fermentation of solution, be only the best outlet of syrup for beer.

Present beer production, mainly based on barley, rice is auxilliary, makes through gelatinization, saccharification, fermentation and postprocessing working procedures, its technical process is as shown in Figure 1;

According to the technology of Fig. 1 as can be seen: the leading portion operation of beer production mainly utilizes the saccharifying enzyme of Fructus Hordei Germinatus self to carry out saccharification, utilizes oneself protease that proteolysis is become amino acid etc.And specialized syrup of beer can directly be used for replacing Fructus Hordei Germinatus because of containing the composition similar to wheat juice, shortens the production cycle, increases substantially production efficiency, cuts down the consumption of energy.

Summary of the invention

Purpose one of the present invention provides a kind of specialized syrup of beer, and this syrup can partly or entirely replace rice, Fructus Hordei Germinatus under the situation that guarantees beer quality, to reduce beer production cost, enhances productivity.

It is simple that purpose two of the present invention provides a kind of production technique, low production cost, and the production efficiency height is fit to the preparation method of the specialized syrup of beer of production greatly.

For the present invention that achieves the above object is the preparation method of such a kind of specialized syrup of beer of realizing:

A, 16～20 ° of Be ' of starch concentration add α～amylase 400～800ml/T (butt starch) and carry out continuous injection liquefaction, 70～110 ℃ of temperature, 20～120 minutes time;

B, adding fungal enzyme 200～500ml/T (butt sugar) carry out saccharification, saccharification time 12～48 hours, 40～80 ℃ of saccharification temperatures, pH value 4.5～7.0;

C, saccharification end, add zein, rice protein, the gluten powder (weight ratio 6: 2: 2) that accounts for butt sugar 5%～30% at saccharifying tank, add acidity or neutral protease then, its amount is 0.2～1% of mixed protein, be hydrolyzed hydrolysis time 40～120 minutes at 35～70 ℃;

D, above saccharification liquid is filtered, remove unhydrolysed albumen, neutralization decolouring then;

Filtrate after E, the decolouring that will neutralize concentrates, and the concentration that gets product is 40～80%.

A kind of specialized syrup of beer, glucose 5～15%; Maltose 45～70%; Trisaccharide maltose 10～20%; Tetrose above 10～20%; Alpha-amino nitrogen 120～180mg/L (10% solid substance); Sugar: non-sugared 1: 0.15～0.35.

Advantage and positively effect

The present invention utilizes advanced biotechnology, and for the production of beer provides a kind of steady quality, production cost reduces, and can partly or entirely replace the specialized syrup of beer of rice, Fructus Hordei Germinatus.Utilize this syrup to carry out beer production and can bring effect preferably:

1, traditional method is produced high-concentration malt wort, and wheat juice yield is low, filtration difficulty, and saccharification time is long and wheat juice color and luster is dark, and specialized syrup of beer can replace rice, Fructus Hordei Germinatus to be applied to high dense brewageing, and the steady quality of wheat juice and production cost are reduced.

2, the high adjunct ratio reaches more than 50%, can directly add in boiling pot, and every pot time syrup only needs about 1 hour, has improved plant factor, effectively alleviates the pressure that the busy season feeds intake.Under the condition that existing equipment need not be changed, increase output about 40%.

3, owing to adopt specialized syrup of beer to replace Fructus Hordei Germinatus that cost of material is reduced, omit saccharification of part prime and wort filtration operation, shortened the cycle of beer production.Comprehensive above factor is considered, makes the ton cost of beer production reduce about 300 yuan.Therefore, the application meeting of specialized syrup of beer brings considerable economic to enterprise.

4, improve beer quality, particularly in the Fructus Hordei Germinatus raw material colourity of using partially deeply and malt quality when poor slightly, can reduce the colourity of wheat juice.Because specialized syrup of beer has replaced the auxiliary material rice, thereby has improved the problem of aging because of using stale rice to bring to beer.

5, the component of specialized syrup of beer sugar is similar to wheat juice, reaches forming of the mineral salt similar to wheat juice, VITAMIN etc. by the reasonable amino acid proportioning that is fit to beer fermentation, very easily in the production of beer.
