查询词典 caproic acid

The results showed that temperature rise would inhibit their esterification capacity, ethyl caproate-producing capability of raw zymin of 1# high-temperature monascus improved with the prolong of the esterification time when ethanol concentration was 4 %vol and caproic acid content was 4 mL, and when ethanol concentration and caproic acid content was within proper range, caproic acid content had more effects on the formation of ethyl caproate by raw zymin than ethanol concentration.

摘 要：着重研究粮食酒发酵中4类产酸菌的分离，其中己酸菌与丁酸菌同属梭状芽孢杆菌，为厌氧菌，醋酸菌为好氧菌，乳酸菌则微好氧，因此各自有不同的分离鉴定方法，其中己酸菌与丁酸菌分离方法相似，丁酸菌与乳酸菌的性能鉴定方法相似，其他则各有特色。

Lipase mediates esterification between caproic acid (0.6mol/L) and ethanol (0.6mol/L) in n-heptane at 40℃. The decrease in caproic acid is measured by titration and 1 unit of lipase synthetic activity is defined as 1 μmol caproic acid consumed per min.
