摘要
以鲜花椒为原料制备半固态调味料鲜花椒膏,进行配方优化、杀菌工艺研究.通过感官评分,确定最佳配方为增稠剂(结冷胶与CMC以3∶7复配)质量分数1.0%、γ-环糊精质量分数0.8%、食用盐质量分数5.0%.以菌落总数、感官评分、麻味物质含量、香味物质含量为指标,确定超高压杀菌500 MPa保压15～20 min为鲜花椒膏的最佳杀菌方式.对花椒膏进行高温保藏试验,确定鲜花椒膏在(37±1)℃条件下储藏20d时品质好.
Abstract
In this paper,fresh Zanthoxylum semisolid seasoning was prepared,the formulation optimization and sterilization process were studied.Through the sensory evaluation,the formula optimization were confirmed as thickener(Gellan gum and CMC are compounded at 3∶7)mass fraction 1.0%,γ-cyclodextrin mass fraction 0.8%and salt mass fraction 5.0%.By comparing the changes of microorganism,sensory score,total fagaramide,volatile flavoured compounds in fresh Zanthoxylum semisolid seasoning,the best sterilization technology was confirmed as 500 MPa maintaining for 15～20 minutes.Using the high temperature preservation test,the shelf-life at(37±1)℃was 20 d.
