摘要: 本文对啤酒酵母溶液采用高压CO2气体杀菌过程进行了试验研究。试验表明,向啤酒酵母溶液中通入高压CO2气体,对啤酒酵母有明显的杀灭作用。CO2气体压力、通气时间、酵母溶液浓度、微孔气体分配管孔径等参数对杀菌效果有明显影响。在1MPa的CO2压力下,通气4min,即可达到37.2%的杀菌率。

Abstract: Experiments on the beer yeast liquid sterilized by high-pressure carbon dioxide were carried out in this paper. Tests showed that, an obvious sterilizating effect on beer yeast was resulted. The sterilizating effects were strongly affected by the parameters, such as the pressure of the carbon dioxide, sterilizing time, the concentration of the beer yeast solution, and the diameter of the micro-pore from which the high pressure CO2 was spouted into the solution. The highest sterilizing efficiency was reached at 37.2% under the test conditions of 1.0MPa CO2 and 4 min sterilizing time.

Key words: sterilization, high-pressure, carbon dioxide, beer yeast
