Beer ultrahigh-pressure jet flow cold sterilization method

Abstract

The invention belongs to the technical field of food processing, and aims at solving the problems of adverse effect on the fresh mouthfeel of beer, much loss of nutritional ingredients and great energy consumption in the prior art. The beer ultrahigh-pressure jet flow cold sterilization method processes beer with ultrahigh-pressure jet flow equipment with a pressure parameter of 100-200MPa and then performs sterile filling. The method provided by the invention can realize thorough beer sterilization, obviously prolongs the quality guarantee period of beer, expands the marketing radius, improves the appearance and mouthfeel, and brings little damage of the nutritional ingredients in beer; and moreover, the equipment volume is small, the investment is small, the energy consumption is low, the pollution is avoided, and continuous production can be realized.

Description

technical field [0001] The invention belongs to the technical field of food processing. Specifically, the method relates to keeping fresh beer by adopting a low-temperature continuous ultra-high pressure jet sterilization method. Background technique [0002] At present, the common commercially available beers are: ①Cooked beer: After the fermentation is completed, use diatomaceous earth for coarse filtration to reduce the yeast in the beer to about 20 / 100ml, and the coarse filtrate is pasteurized to kill the yeast in the beer. Microorganisms, the beer produced is cooked beer. ②Draft beer: The above coarse filtrate is finely filtered and sterilized by microporous filtration technology, and the produced beer is draft beer. [0003] Traditional cooked beer has a long shelf life due to thorough sterilization, but the equipment is huge, consumes a lot of energy, and loses the refreshing taste of fresh beer, causing more damage to its nutrients; modern draft beer has a good tas...
