摘要: 以盐渍仿刺参为研究对象,以感官评分和脱水速率加权后的综合评分作为评价指标,采用单因素试验及响应面法对冷风干制(cold-air drying,CAD)工艺条件进行优化,并对CAD、真空冷冻干制(vacuum freeze drying,VFD)、热风干制(hot-air drying,HAD)和真空微波干制(vacuum microwave drying,VMD)工艺处理的仿刺参进行品质比较分析。结果表明:CAD最佳干制工艺条件为真空脱盐时间4.2?h、冷风温度19?℃、冷风风速1.70?m/s,仿刺参的综合评分为0.77。在营养保持方面,VFD和CAD比HAD和VMD效果更好;在热收缩率方面,HAD>VMD>CAD>VFD,其中CAD和VFD差异不大;在复水倍数方面,CAD>VFD>HAD>VMD;在质构特性上,CAD和VFD质构指标明显优于HAD和VMD。对比结果说明CAD在工业生产中具有更高的实用性。

Abstract: The present work was done to optimize the process conditions for cold-air drying (CAD) of pickled Apostichopus japonicus by the combined use of one-factor-at-a-time method (OFAT) and response surface methodology (RSM). The response variable was the weighted average of sensory scores and dehydration rate. A comparison of CAD, vacuum freeze drying (VFD), hot-air drying (HAD) and vacuum microwave drying (VMD) was performed in terms of the quality of dried products. Results?showed that?the optimal cold-air drying conditions were determined as follows: vacuum desalination time, 4.2 h; drying temperature, 19 ℃; and wind speed, 1.70 m/s, resulting in a weighted average of 0.77. With respect to nutrient retention, VFD and CAD were?better than HAD and VMD. In terms of heat?shrinkage, the drying methods were in the decreasing order of HAD, VMD, CAD and VFD with only a marginal difference being observed between CAD and VFD, while they followed the decreasing order of CAD, VFD, HAD and VMD in terms of rehydration rate. In terms of textural characteristics, CAD and VFD were better than HAD and VMD. These?results?showed?that CAD was more practical in industrial production.
