Embodiment 1

[0024] Grading: The barley is first cleaned to remove impurities and then graded according to size, divided into three grades: high-quality barley, upper-middle-grade barley, and lower-middle-grade barley;

[0025] Barley soaking: At this stage, the sludge and floating wheat are rinsed at the beginning, and 1%-3% quicklime is added for disinfection after changing the water, so that the barley to be germinated can absorb sufficient water and partly remove endogenous hormones that inhibit germination. Soak the wheat by spraying method, the water temperature is 17℃~18℃;

[0026] Germination: At 14°C-18°C, spray GA solution evenly after the barley turns white (0.2gGA is needed for each ton of barley, and 20mg.L -1 solution, the water temperature is 14°C to 16°C, ventilated (oxygen supply, carbon dioxide discharge), and wheat turning; after 12 hours, evenly spray 6-BA solution (0.1g per ton of barley, made into 10mg.L -1 solution, the water temperature is 14°C to 16°C), ventilate ...

Embodiment 2

[0037] The difference with example 1 is only that the amount of gibberellin used becomes 0.3g per ton of barley (made into 30mg.L -1 solution), 6-BA 0.2g (dubbed 20mg.L -1 solution), BR is still 0.01g (dubbed 1mg.L -1solution), water temperature 14 ℃ ~ 16 ℃, other processing methods and processes are the same as in Example 1. The germination time is 108 hours, and the germination rate reaches more than 92%. The prepared maltosaccharification power is 225.0WK, the extract is 76.4%, α-amino nitrogen is 130.5mg.100g -1 , reaching the quality standard of first-class malt. This embodiment is suitable for barley raw materials of medium to high quality.

Embodiment 3

[0045] The difference with example 1 is only that the amount of gibberellin used becomes 0.5g per ton of barley (made into 50mg.L -1 solution), 6-BA0.2g (dubbed 20mg.L -1 solution), BR is still 0.01g (dubbed 1mg.L -1 solution), water temperature 14 ℃ ~ 16 ℃, other processing methods and processes are the same as example 1. The germination time is 120 hours, and the germination rate reaches more than 90%. The prepared maltosaccharification power is 210.5WK, the extract is 74.6%, and the α-amino nitrogen is 120.0mg.100g -1 , up to the standard of qualified malt.

[0046] This example is suitable for barley raw materials of medium and low quality.

Abstract

The invention discloses a method for accelerating germination in beer barley malting by combining brassinolide (BR), 6-benzyladenine (6-BA) and gibberellic acid (GA), so as to change a process for accelerating barley germination by singly using the gibberellic acid during the prior malting, reduce the amount of the gibberellic acid, improve the germination ratio of the barley, shorten the germination time, and avoid increased hidden trouble of chromaticity of malts caused by using a large amount of the gibberellic acid; and the property of the brassinolide is utilized to improve the mixed-bacteria resistant performance of green malts so as to finally achieve the aims of improving the quality of the malts and reducing the production cost. The method comprises processes of grading, soaking the malts and germinating, and is applied in different periods of the barley germination process through using the brassinolide (BR) with extremely low concentration, efficiency and natural plant hormone and the gibberellic acid (GA) and cytokinin (6-BA) with different concentrations, thereby shortening the germination time by more than 24 h and improving five percentage points of the germination ratio.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing and production, and relates to a production method of beer barley malt, in particular to a new malting method using brassinolide, gibberellin and cytokinin as barley germination accelerators. Background technique [0002] China is the world's largest beer production country, and barley malt is the main raw material for beer brewing. Therefore, the huge market of the beer industry has driven the rapid development and growth of domestic malt production enterprises. Since the quality and price of malt can affect the quality and price of beer, the technical transformation and level improvement of malt production technology is not only related to the economic benefits and development of malt production enterprises, but also has a huge impact on the survival and development of beer production enterprises. [0003] At present, my country's malt production enterprises generally ado...
