正交试验优化鹿角胶的晾胶工艺

Optimization of air-curing of Cervi Cornus Colla by orthogonal test

目的优化鹿角胶的晾胶工艺。方法采用正交试验和多指标综合评分法,以鹿角胶块的失水率、胶块表观率为指标,对影响晾胶效果的温度、湿度、翻胶时间3个因素进行研究。结果鹿角胶的最佳晾胶工艺为温度25℃,湿度40%,翻胶时间36 h。结论所优选的工艺具有散失水分快、胶块表面完整等优点,为鹿角胶工业化晾胶提供实验依据。

Objective To optimize the air-curing technical of Cervi Cornus Colla. Methods The process was optimized by orthogonal design and multi-index grading method. The filtration rate and surface apparent of Cervi Cornus Colla were assessed, to investigate the leading factors for drying glue-temperature, humidity, and doubling time. Results The best technical was 25 ℃ for temperature, 40% for humidity, and doubling Cervi Cornus Colla of 36 h/time. Conclusion The optimization of process has quick water loss, surface integrity of gelatin, and to provide experiment basis for Cervi Cornus Colla industrial drying glue.
