摘要: 为选择一种较为适合复合面条的干燥方法,本实验以马铃薯全粉和小麦粉为原料制成复合面条,通过热泵干燥、热风干燥、冷风干燥、红外干燥4?种方法对其进行干燥,并对其各个指标进行测定,利用变异系数法获取4?种干燥方法的综合评分,确定最佳干燥方式。结果表明:干燥方式对各指标的影响显著(P<0.05),断条率、吸湿性、干燥能耗、烹调损失率和咀嚼性这5?个指标所占权重较大;其中,断条率的权重最大。综合评分结果表明:热泵干燥的复合面条品质最优(综合评分:0.239),其次是热风干燥(综合评分:0.201),冷风干燥次之(综合评分:-0.062),红外干燥的复合面条品质最差(综合评分:-0.701)。在此实验条件下,热泵干燥的复合面条品质最好,因此热泵干燥为最佳的干燥方法。

Abstract: In order to select a suitable drying method for composite wheat-potato noodles, this study evaluated and compared the effects of four drying methods of heat pump drying, hot air drying, cold air drying and infrared drying on the drying characteristics, quality attributes and microstructure of noodles. Overall evaluation scores of the four drying methods were obtained based on coefficient of variation. The results showed that the drying methods had significant influence on all investigated parameters (P < 0.05), and breaking rate, hygroscopicity, drying energy consumption, cooking loss rate and chewiness accounted for a larger proportion of the overall evaluation, with breaking rate contributing to the largest proportion. The results of the comprehensive evaluation showed that the quality of the composite noodles dried by heat pump drying was the best (comprehensive score of 0.239), followed sequentially by hot air drying (comprehensive score of 0.201), cold air drying (comprehensive score of ?0.062), and infrared drying (comprehensive score of ?0.701). Accordingly, heat pump drying is the best drying method.
