Abstract

The invention provides a method for brewing beer from corn particles and belongs to the field of beer fermentation. The method comprises the following process steps: producing corn particles by employing a dry degerming technology, taking the corn particles with the particle size of 0.3-0.5mm as auxiliary materials, and saccharifying, gelatinizing and fermenting to obtain the corn particle beer. The obtained corn particle beer is light in oxidized flavor, high in non-biological stability, rich in foam, high in foam retention, long in beer refreshing period and high in nutritive value.

Description

A kind of Corn particle beer and manufacture method thereof
Technical field
The present invention relates to a kind of Corn particle beer and manufacture method thereof, belong to brewage field.Background technology
Corn is the main grain variety of China, is except wheat, the dry crop that output is maximum.Adopt corn to substitute rice and make auxiliary material, hold out broad prospects.A research of nutritive health-care association of Germany shows, in all staple foods, the nutritive value of corn and health-care effect are the highest.In corn, vitamin contents is very high, is 5-10 times of rice, wheat.Meanwhile, except containing except carbohydrate, protein, fat, carotene, also containing the nutritive substance such as riboflavin, VITAMIN in corn.These materials have very large benefit to the disease such as preventing heart disease, cancer.Corn contains 7 kinds of effective nutraceutical agents---calcium, gsh, VITAMIN, magnesium, selenium, vitamin-E and lipid acid.
China is comparatively ripe as the research of auxiliary material beer brewing for W-Gum, but due in the production technique of W-Gum, needs to add certain sulfurous gas, cause the finished beer finally obtained to be easy to containing a kind of discordant foreign odor taste.Also useful Semen Maydis powder is cooked the report of beer, but Semen Maydis powder existence is easily lumpd after feeding intake, and becomes pimple, is unfavorable for the defects such as the carrying out of gelatinization.
The present invention adopt dry method to take off corn particle that embryo technology obtains makes beer, can overcome above defect, it is little that dry method takes off the investment of embryo technical matters, and process cost is low, and energy consumption is low, pollution-free.Adopting dry method to take off the corn particle that embryo technology obtains is that auxiliary material carries out brewageing of beer, has no research at home.Corn particle brewing beer, may cause raw material availability on the low side, but this case is by after the use kind of gelatinization technique and zymin and dosage optimization, and this problem obtains good solution.Take corn particle as the beer that auxiliary material is brewageed, activated flavour is comparatively light, foaming abundancy, and holding property of bubble is good, and do not have W-Gum to be the foreign odor taste of auxiliary material brewing beer, mouthfeel is more mellow than the beer of W-Gum brew.Also can not produce to feed intake and cause difficulty.
Summary of the invention
W-Gum is comparatively ripe as the technique of auxiliary material beer brewing, but due in the production technique of W-Gum, needs to add a certain amount of sulfurous gas of interpolation and soak, finally cause containing a kind of foreign odor taste in beer.Corn flour cooks beer can cause caking, is difficult to a uniform difficult problem.Therefore the technical problem that the present invention mainly solves is exactly be auxiliary material for the method for brewage and suitable condition by research corn particle, produce one and avoid foreign odor taste, and the more mellow technique of mouthfeel is beneficial to Corn particle beer and the production method thereof of operation.
In order to realize the object of the invention, the technique means of main employing is: take off the corn particle that embryo technology obtains by adopting dry method in beer saccharification process as auxiliary material, namely in saccharifying, add the corn particle of raw material weight 40%-70%, and by the interpolation of neutral protease in gelatinization process, improve the leaching yield of corn particle, finally obtain the Corn particle beer that a kind of mouthfeel is more mellow, local flavor is softer.
The concrete technological process of production of the Corn particle beer that the present invention is overall is: corn takes off the pulverizing of embryo technology through dry method and obtains corn particle, particle diameter is selected to be that the corn particle of 0.3-0.5mm is through gelatinization, post liquefaction, enter brew kettle and malt meal and after wine with dregs saccharification, add the corn cob after the pulverizing of total raw material weight about 2% again, squeeze into together in filter vat, add corn cob be conducive to corn particle usage ratio large time filtration, boil successively after filtration, after cooling, inoculation yeast is also filled with oxygen, through fermentation, filter, filling, the steps such as sterilization, finally obtain Corn particle beer.
The mainly concrete experimental technique of the present invention is: in gelatinization process, first by corn particle, (corn particle is too little is unfavorable for processing, particle is too large affects gelatinization effect, particle diameter is selected to be 0.3-0.5mm after test) adopt 50 DEG C to feed intake, add appropriate neutral protease and fire resistant alpha-diastase, keep 20 minutes at 50 DEG C after feeding intake, proteolytic enzyme is acted on fully.Then be warmed up to 90 DEG C, keep 30 minutes, then be warmed up to 100 DEG C, after boiling 30 minutes, mash is incorporated in brew kettle.Keep 30 minutes at 50 DEG C after brew kettle Fructus Hordei Germinatus feeds intake, and after wine with dregs, be warming up to 67.5 DEG C of insulations 40 minutes, after be warming up to 78 DEG C of insulations 10 minutes, add ground corn core, filter.Wort cooling after boiling convolution precipitation is to temperature 9-10 DEG C, and constantly pass into sterile air in process of cooling, make wheat juice dissolved oxygen at 8-10mg/L, enter subsequent fermentations, fermentation ends obtains Corn particle beer.
The beneficial effect that the present invention obtains is:
1, the Corn particle beer that prepared by the present invention meets the indices of GB beer, the beer smell brewageed and mouthfeel are all better than the beer of W-Gum as auxiliary material, specifically, dry method is adopted to take off embryo technology, avoid adding of sulfurous gas, thus obtain the foreign odor taste that smell aspect does not have W-Gum, a Corn particle beer that the beer brewageed than W-Gum of mouthfeel aspect is more mellow.
2, employing particle diameter is the corn particle of 0.3-0.5mm is auxiliary material, and lipid content is low, and the flavour of oxygen in beer obtained is comparatively light, foaming abundancy, and holding property of bubble is good.Can spongy structure be formed after saccharification, be beneficial to wort filtration.
Only amylase can be added in the process of 3, general gelatinization, this case is found by research, corn starch granules is by protein encapsulation, decrease amylase to contact with the effect of starch granules, this reduces the leaching yield of starch, by experiment aspartic protease, the action effect of neutral protease and Sumizyme MP, find neutral protease most pronounced effects, and usage ratio is that 20-50mg/l effect is best.
4, the ground corn core natural goods that the present invention uses pollutes, and as good filtration medium, can be conducive to beer filtration quick.
