Preparation method of composite beer syrup

Abstract

The invention relates to a preparation method of composite beer syrup, belonging to the technical field of syrup preparation. The method comprises the following steps: inoculating a supernatant obtained by stirring and centrifuging biogas slurry and distilled water into a self-made screening culture medium, culturing, collecting the eluent, mixing the eluent with a liquid in humifuse euphorbia herb stems and a phosphoric acid solution to obtain a fermentation base solution, grinding bagasse, apple peel and the like, uniformly mixing the ground substance with the fermentation base solution, heating to perform fermentation, filtering the fermentation mixture, and carrying out adsorptive decolorization on the filtrate by using activated carbon, thereby obtaining the composite beer syrup. The composite beer syrup has the advantages of reasonable syrup components and high alpha-amino nitrogen content (up to 190-210 mg/L). The glucose content is lower than 8%, and the maltose content is up to 55-58%. The degree of fermentation can be effectively enhanced to 68.7-75.2%.

Description

technical field [0001] The invention relates to a method for preparing compound beer syrup, which belongs to the technical field of syrup preparation. Background technique [0002] Beer is known as "liquid bread". It is rich in nutrition, especially its mellow, round, soft and refreshing taste makes it one of the most produced and sold beverages in the world. Traditional beer is brewed with barley and hops As the main raw material, barley forms soluble matter α-amino nitrogen and total nitrogen, protein and its decomposition products during the germination process, and the carbon source contained in barley itself is an indispensable nutrient for yeast, while hops endow beer with unique Flavor and trace components, both of which have an important impact on the flavor, foam retention and stability of beer. In recent years, enterprises have widely used a large number of auxiliary materials, such as rice, corn and other grains. Although the amount of malt can be reduced, the p...

Problems solved by technology

[0004] The technical problem to be solved by the present invention: the high molecular protein content in beer syrup prepared from cornstarch is low, the free α-amino nitrogen content is low, and the glucose content is high, and the fermentable syrup is low, which cannot meet the needs of fermentation , leading to the problem that the quality of the syrup is not high, the present invention inoculates the supernatant obtained by stirring and centrifuging the biogas slurry and distilled water into the self-made screening medium, after culturing, collects the eluate, and mixes it with the stem of Dijin grass The liquid in the mixture and the phosphoric acid solution are mixed to prepare the fermentation base liquid, then the bagasse, apple peel and other materials are ground, mixed with the fermentation base liquid evenly, heated and fermented, the fermentation mixture is filtered, and then activated carbon is used to The filtrate is subjected to adsorption and decolorization to prepare compound beer syrup. The composition of the syrup in the compound beer syrup prepared by the present invention is reasonable, which improves the fermentation degree of beer production and is conducive to the popularization and use of beer syrup
