| 摘 要： | 从自由基反应和老化物质角度,综合几种单一老化评价方法,通过数据处理方法和数学运算,提出综合老化评价指标。综合老化评价指标能较好反映不同老化程度啤酒的老化情况。同时发现,基于自由基反应原理的老化评价方法,在评价啤酒老化准确性上可与现有的、基于老化代表性物质的老化评价方法相当。

| Abstract: | Complex indices were set up to evaluate beer aging degree.Firstly,several singlet evaluation methods were investigated based on free radical reactions and off-flavor compounds respectively.Then they were combined by statistical analysis and mathematical calculation to bring forward the complex evaluation indices,which were proved to have a better correlation with beer aging compared with single evaluation indices.Evaluation system on free radical reactions was equal to that based on staling flavor compounds in beer aging evaluation. |

| Keywords: | complex evaluation aging index free radical staling beer |
