Embodiment 1

[0037] The present invention provides a kind of preparation method of high stability blueberry beer, and its preparation raw material comprises malt, blueberry leaf, blueberry etc., concrete steps are as follows:

[0038] 1. Raw material crushing: crush the malt and blueberry leaves separately;

[0039] 2. Ultrasonic-assisted extraction of blueberry leaves and malt mashing: Add crushed malt and blueberry leaves to the ultrasonic extractor at a ratio of 50 to 200:1, the ratio of material to water is 1:4, and the ultrasonic extraction temperature is maintained at a suitable temperature for protein decomposition The temperature of the action is 50±3°C, the ultrasonic power is 60-220w, and the ultrasonic time is 10-30min. Next, the ultrasonic temperature is adjusted to 65±3°C, the ultrasonic power is 180-420w, and the ultrasonic time is 20-40min. Finally, the ultrasonic temperature is raised to 78 Maintain at ±3°C for 10-15 minutes to obtain mash.

[0040] 3. Filtration: Afterwar...

Abstract

The invention discloses a method for preparing high-stability blueberry beer. The method comprises the following steps: mixing the crushed malt and blueberry leaves, thereby obtaining a mixture I; ultrasonically treating the mixture I under the conditions of the material-water ratio of 1:(3.5-1:5), the temperature of 50+/-5 DEG C and the ultrasonic power of 60-220W for 10-30 minutes; ultrasonically treating the mixture I under the conditions of the temperature of 65+/-3 DEG C and the ultrasonic power of 180-420W for 20-40 minutes; finally maintaining the mixture I at the temperature of 78+/-3 DEG C for 10-15 minutes, obtaining converted mash, filtering, thereby obtaining the clarified blueberry leaf and malt leaching solution; adding hops into the blueberry leaf and malt leaching solution, and adding blueberry juice; and adding beer yeasts, fermenting and the like. The blueberry beer or blueberry black beer made by using the method is red and bright in color, clarified in wine body, lasting in foam suspension on cups, mellow in taste, good in bitterness and good in mouthfeel, has blueberry fruit flavor, hop aroma or unique scorched flavor of black beer and also has high colloidal stability and flavor stability.

Description

technical field [0001] The invention relates to a preparation method of blueberry beer, in particular to a preparation method of high-stability blueberry beer. Background technique [0002] Beer is one of the most popular alcoholic beverages in the world, ranking third only to water and tea in the entire beverage consumption. Beer is made up of water, grains, yeast and hops. Hops play a vital role in beer and are the "soul of beer". It not only gives beer the pleasing bitterness, but also contributes a rich hop aroma. There are many kinds of beer, and different beer tastes and colors are very different. [0003] Blueberry is a plant of the genus Vaccinium in the Rhododendron family, also known as persimmon and bilberry. Because the fruit is blue, it is also called blue berry. It is one of the rare true blue foods on the earth. The fruit of blueberry It is blue in color and covered with a layer of white fruit powder. The flesh is delicate, the fruit taste is sweet and sour...
