Embodiment Construction

[0038]The pilot test of producing alcohol-free beer by reverse osmosis was carried out according to the process shown in the accompanying drawing. Put 100L sake in the feed tank, pump it into the reverse osmosis membrane system for dealcoholization by a high-pressure pump, control the flow rate of additional deoxygenated water to be equal to the flow rate of the permeate, and the concentrated liquid still flows back to the feed tank for circular dealcoholization , until the alcohol content is lower than 0.5% (v / v). The operating pressure is 1.8-2.5Mpa, the operating temperature is 4-12°C, and the reverse osmosis is permeated for 16 minutes first (both the permeate and the concentrate flow back into the feed tank) to stabilize the permeability of the membrane. The indexes of original wine and non-alcoholic beer obtained after dealcoholization were analyzed and compared.

Abstract

The present invention is reverse permeation process of producing alcohol-less beer, and relates to the application of reverse permeation technology in beer producing industry. Beer is pumped into reverse permeating unit, permeated liquid flow rate is controlled to equal to that of replenished deoxidized water, and concentrated liquid is returned into the feeding tank for circulated dealcoholization until alcohol content in beer lower than 0.5 vol%. The reverse permeation is controlled to have the reverse permeated liquid is 4-5 times the volume of the material liquid, the operation pressure of 1.8-2.5 MPa and the temperature of 4-12 deg.c. The reverse permeation process of producing alcohol-less beer can lower alcohol content by over 85 % and has no need of altering the available beer producing process, and the alcohol-less beer has the original flavor of beer maintained and delicious taste.

Description

technical field [0001] The invention discloses a method for producing alcohol-free beer by reverse osmosis, which relates to the application of reverse osmosis technology in the beer industry. Background technique [0002] my country's GB4927-2001 "Beer" stipulates that beer with an alcohol content of 0.6%-2.5% (v / v) is "low alcohol beer", but there is no definition for alcohol-free beer. my country's beer industry generally follows the definition of non-alcoholic beer (alcohol free beer) in European and American countries, that is, beer with an alcohol content of <0.5% (v / v) is called non-alcoholic beer. [0003] Alcohol-free and low-alcohol beer that "looks like beer, smells like beer, and tastes like beer" has the color, aroma, and taste of ordinary beer except for its low alcohol content, which is in line with the trend of low-alcohol alcohol. The development of globalization and the trend of beverages towards health care. As early as the late 1980s and early 1990s,...
