7°BX淡爽型啤酒的研究

Studies on the Brew of 7 BX Light Beer

本文以改善低原麦汁浓度啤酒质量为目的,提出了一种新颖的淡爽型啤酒的酿造方法.采用70%麦芽和30%的大米的原料配比及二次煮出法二段式糖化,经正交试验得到了较佳的糖化工艺,可以控制麦芽汁的糖与非糖比值.并在糖化中添加压榨啤酒废酵母的水解液进行麦汁制造和啤酒发酵,其工艺进展顺利.所酿制的成品啤酒口味纯正,泡沫持久性好.1000kg啤酒原料成本与12°BX啤酒相降低了41,6%左右,年产10Mkg啤酒工厂可节约原料成本约110万元.

This paper proposes a new method to brew beer in order to improve the quality of the beer which contains a low concentration of sweet wort. Using the method of two time boiling and mashing procedure with 70% malt and 30% rice. Cross-test is adopted to prepare sweet wort and beer fermentation. Then a ideal mashing method which can control reducing sugar to unreducing sugar has been obtained. The processes are successful. The finished beer by adding compressed yeast's tydrolytic liquid during the mashing procedure gets a long foam duration obuiously and its taste is very pure. The cost of meterials each ton beer is reduced about 41.6% and saved about 1,100,000 yuan in a factory of the annual output of 107 kilogram beer, compared with 12°BX beer.
