A kind of preparation method of milk beer

Abstract

The invention discloses a method for preparing milk beer. The method comprises the following steps: (1) gelatinizing rice as an auxiliary material; (2) saccharifying malt undecanted wine, namely, mixing water with crushed malt, heating and performing heat preservation to obtain the saccharified malt undecanted wine, simultaneously stopping gelatinizing the auxiliary material rice and saccharifying the malt undecanted wine, mixing the saccharified malt undecanted wine and the gelatinized undecanted wine obtained in the step (1) to obtain mixed undecanted wine, adding milk into the mixed undecanted wine, heating and performing heat preservation to obtain main saccharified undecanted wine, heating the main saccharified undecanted wine and filtering to obtain malt juice; (3) filtering the malt juice; (4) fermenting the malt juice. According to the method, as milk is added in the main saccharifying process, the milk protein is decomposed into alpha-amino nitrogen, peptide and middle molecule protein by protease in the saccharified undecanted wine, and a sufficient nitrogen source is provided for yeast, so that the use amount of malt is correspondingly reduced, the beer has the milk fragrance, and the conventional refreshing taste and the clear appearance of the beer are not reduced.

Description

technical field [0001] The invention relates to the technical field of beer brewing. Background technique [0002] Beer is the oldest alcoholic beverage for human beings, and it is the third most consumed beverage in the world after water and tea. Beer is a low-alcohol wine containing carbon dioxide brewed by yeast fermentation with barley malt, hops and water as the main raw materials. It has the aroma of hops and malt and is rich in nutrition. [0003] The single taste of traditional beer cannot meet the needs of different consumers, and various other flavors of beer have emerged as the times require, such as milk-flavored beer and so on. The preparation method of milk beer has two kinds at present. One is to ferment directly with skimmed milk (or milk powder) and sugar; the other is to ferment milk and wort together with the traditional beer production process; the appearance of milk beer produced by the first method is more like milk or milk beverage Although the nutr...

Problems solved by technology

One is to ferment directly with skimmed milk (or milk powder) and sugar; the other is to ferment milk and wort together with the traditional beer production process; the appearance of milk beer produced by the first method is more like milk or milk beverage Although the nutritional value is high, it lacks the proper flavor of beer due to the large difference between raw materials and technology and traditional beer. The milk beer produced by the second method is closer to beer in raw materials and technology, and has a full beer flavor. But the current second method has a low technological level, and the milk beer produced has poor milk taste and poor color
