Problems solved by technology

The fermentation method simply adds fruit when making the wort, and then ferments the beer. The beer produced by this method tends to lose the fruit flavor, which violates the original intention of flavor beer production; the blending method is to blend the beer with fruit juice after the fermentation is completed. This method is suitable for fruits with high water content, but after blending, the flavor of fruity beer often deviates from the unique flavor and taste of beer itself, and it is easy to lose the nutrition and flavor of fruit pulp

Abstract

The invention discloses a preparation method of Hami melon flavor beer. The method changes a traditional flavor beer fermentation process and comprises the following steps: adding Hami melon pulp during a malt hydrolysis process, then performing fermentation to produce beer with light Hami melon flavor and nutrients, and finally blending the fermented raw beer and Hami melon juice to form the Hami melon flavor beer. The method has the following advantages that nutrient substances in the Hami melon pulp are reserved; and the Hami melon flavor beer is endowed with a unique Hami melon flavor, has Hami melon fragrance on the basis of keeping the original beer flavor, has excellent color, fragrance and bitter taste, tastes good, contains abundant vitamins, mineral substances, organic acid, amino acid and the like, contains 3-6 percent of alcohol, has the effects of cooling to relieve summer heat, clearing lung and suppress cough, relieving dysphoria with smothery sensation and the like, meets the demands of different consumers and has a board market popularization prospect.

Description

technical field [0001] The invention relates to microbial fermentation technology, in particular to a method for preparing cantaloupe-flavored beer, which belongs to the technical fields of biotechnology and light industrial production. Background technique [0002] The beer fermentation in the prior art is to saccharify barley malt and add hops to prepare wort under certain conditions, and then use brewer’s yeast to ferment the fermentable substances in the wort to produce alcohol, carbon dioxide, higher alcohol A series of metabolites such as volatile esters, aldehydes and acids become beer. Beer is the beverage with the lowest alcohol content in alcoholic beverages. It contains a variety of amino acids and a large amount of amino acids. It has high calorific value and is easily digested and absorbed by the human body. It occupies a large share in the alcoholic beverage market. Hami melon is rich in nutrition and has medicinal value. It contains protein, dietary fiber, ca...
