通过对不同贮藏温度下马铃薯块茎的还原糖含量及加工品质色泽指数的测定，筛选出在简易库房贮藏条件下（４～１０℃）适于加工的品种为国引ｌ、１１、１３、２、１２号，这些品种经过３个月的低温贮存还原糖积累水平较低（＜０．５％），色泽指数小（＜２０），加工品质好．冷贮（０～２℃）和冷贮一回暖（１５～１７℃）处理结果表明，冷贮导致块茎中还原糖含量大幅度提高，色泽指数显著增大．而经过回暖处理后，还原溏含量下降，色泽指数变小，但不同的品种经不同的处理时间回暖效果不一。国引１、２号经过３０天的回暖处理，加工品质达到商业要求．
Through measuring the content of reducing sugar and the color index of processing quality under different storage temperatures, the varieties suitable for processing under the condition of simple storeroom storage (4 ~ 10 ℃) were selected as Guoling l, 11, 13, On the 12th, these cultivars had low accumulation of reducing sugars (<0.5%) after 3 months of storage at low temperature, with small color index (<20) and good processing quality. Cold storage (0 ~ 2 ℃) and cold storage one warm (15 ~ 17 ℃) treatment results show that cold storage led to a substantial increase in reducing sugar content in tubers, color index increased significantly. After the warmer treatment, the content of reduced 溏 decreased, the color index decreased, but different varieties of different treatment time to pick up the results vary. Guotai 1, 2 after 30 days pick-up processing, processing quality to meet commercial requirements.
