摘要
本试验在挤压大米啤酒辅料的实验室糖化、发酵试验基础上,在山东邹城无名啤酒厂进行了生产试验,用挤压机加工的30t不加酶大米啤酒辅料,酿造400t啤酒。试验表明:挤压不加酶大米啤酒辅料的麦汁糖化过滤均较顺利进行,麦汁浸出物收得率有时高于对照的传统不挤压大米啤酒辅料0.34%,有时低于对照样,其主要原因是挤压不加酶大米啤酒辅料在水中易结块,辅料中的淀粉降解的不彻底,糖化效果不理想所致。
Based on saccharification and fermentation experiments at laboratory for extrusion of beer rice adjunct, the productive experiments was studied at Shandong Zhou City Beer Brewery . The 30t extruded beer adjunct without enzyme were used for brewing 400t beer. The test results indicate the saccharification and filtration were carried on successfully. The recoverable ratio of wort extract of extruded beer adjunct is 0.34% more than that of non - extruded beer adjunct some- times, but . it less than that of non - extruded beer adjunct sometimes. The main reason is non - extruded beer adjunct mass easy many dollops in mash and the saccharification effect is not better.
