Used with potato as the main raw material to produce potato granule powder.According to the single factor experiments, optimization of freeze-drying conditions using response. The results showed:pre freezing time 2.5 h, diaphragm temperature 50℃,loading on 1.4 kg, corresponding for freeze-drying time 4.41 h, best quality.%以新鲜马铃薯为原料,制作马铃薯颗粒粉,在单因素试验的基础上,利用响应面对冻干条件进行优化,结果表明:预冷冻时间为2.5 h,搁板温度为50℃,装料量1.4 kg,对应的冻干时间为4.41 h时成品品质最佳.
