Problems solved by technology

Due to the blockade of foreign technology and the lack of domestic research on the preparation process of crystallized malt, at present, the crystallization rate of crystallized malt produced by ordinary processes is low, only about 20%, and it is very important to find a method for the preparation of crystallized malt with a high crystallization rate

Abstract

The invention discloses a method for increasing the crystallization ratio of crystallized malt, and belongs to the technical field of beer brewing. According to the method, barley serving as a raw material is malted, saccharified, baked and charred to obtain the full crystallized malt with glass plastids inside. In the malting process, steeping temperature (14-15 DEG C) is slightly increased, water is repeatedly supplemented in the germination process, and the water content of the green malt is increased and about 42%-44%. In the proteolysis and saccharification process, in order to ensure uniformity of the water content and the quality of the malt, about 200g of green malt is directly soaked in 1L of water and saccharified. At present, the crystallization ratio of the crystallized malt can be only about 20%, but the crystallization ratio of the crystallized malt prepared by the method can reach 80% or more.

Description

technical field [0001] The invention relates to a method for increasing the crystallization rate of crystallized malt, which belongs to the technical field of beer brewing. Background technique [0002] Whether at home or abroad, craft beer has become a development direction that cannot be ignored, and has considerable market prospects. Craft beer has higher requirements for raw materials than industrial beer. Malt is the main raw material for beer brewing, which can be divided into common malt and special malt. In addition to ordinary malt, craft beer must also add special malt, such as crystallized malt. With the rise of craft beer, the demand for crystallized malt is also increasing. However, the crystallized malt currently used in China mainly relies on imports, and the domestic ability to independently produce high-quality crystallized malt still needs to be improved. In order to break the monopoly of foreign countries, it is essential to accelerate the pace of resea...
