摘  要：
优化对番木瓜变温压差膨化干燥工艺,基于响应面的中心组合设计方法,分析预干燥时间、膨化温度、抽空时间3个因素对番木瓜膨化产品含水率、硬度、脆度、色泽和复水比5个指标的影响。采用因子分析法确定5个指标的权重,通过综合评分得到番木瓜变温压差膨化干燥的最佳工艺参数范围。结果表明:预干燥时间、膨化温度、抽空时间三因素对产品的含水率、硬度、脆度、色泽和复水比均有显著影响(P<0.05),且三因素交互作用对产品品质影响显著;番木瓜变温压差膨化最优干燥参数为:预干燥时间4.96~6.00 h、膨化温度80.00~97.23℃、抽空时间2.02~3.00 h。

摘  要：
The explosion puffing drying of papaya was optimized by central composite design coupled with response surface methodology. The effect of pre-drying time, puffing temperature and vacuum drying time on five product quality parameters including moisture content, hardness, crispness, color and rehydration ratio were examined. In the final experiment, the suitable parameters were obtained by comprehensive scores through factorial analysis of these five quality parameters. The results indicated that pre-drying time, puffing temperature and vacuum drying time had a great impact on the moisture content, hardness, friability, color and rehydration rate of dehydrated products, and the influence of interactions among three factors on the quality of dried papaya was significant(P < 0.05). The best drying conditions were determined as follows: predrying time, 4.96-6.00 h; puffing temperature, 80.00-97.23 ℃; and vacuum drying time, 2.02-3.00 h.
