摘要 将啤酒糟与统糠均匀混合配制成含水量分别为40%(Ⅰ组)、50%(Ⅱ组)、60%(Ⅲ组)、70%(Ⅳ组)的4种处理,袋装发酵贮藏,在30、60、90、120d开袋取样进行感官评定,测定pH值、氨态氮、干物质、粗蛋白、中、酸性洗涤纤维及有机酸,结果表明:感官评定Ⅰ、Ⅱ、Ⅲ组明显优于第Ⅳ组;pH值和NH3-N/tN的评定Ⅰ组(3.83、3.63%)、Ⅱ组(3.45、4.84%)和Ⅲ组(3.51、4.77%)均低于Ⅳ组(3.91、5.58%);乳酸含量Ⅰ组(1274.15μmol/g)、Ⅱ组(1368.35μmol/g)和Ⅲ组(2661.82μmol/g)均高于Ⅳ组(853.14μmol/g);粗蛋白、干物质、中性洗涤纤维、酸性洗涤纤维分解率随发酵时间增加逐渐增大且趋于稳定。
