响应面法优化曲拉的预脱水工艺
Optimization of the pre-dehydration process of qula by response surface method
摘要
Abstract
The objective of this study was to optimize the process conditions of pre-dehydration.On the basis of single-factor test,the pre-dehydration pressure,the clot water content and the pre-dehydration time were processing parameters and qula chroma comprehensive score was evaluation index.And then the response surface methodology was used to establish qula predehydration process model.The results showed that the order of the three factors effecting on the Qula chroma comprehensive score was:pre-dehydration pressure ＞ pre-dehydration time ＞ clot water content;the interaction between pre-dehydration pressure and pre-dehydration time and the interaction between the clot water content and the pre-dehydration time were extremely significant(p ＜ 0.01).The optimum pretreatment conditions were that pre-dehydration pressure was 300 N,clot water content was 29％,and pre-dehydration time was 3 h.Under the condition,the qula chroma comprehensive score of the product was 0.930,and the theoretical predictions was 0.944.Their relative error was 1.48％.It proved that this parameter can be used for the pre-dehydrationactual production of qula.关键词
