摘要
马铃薯加工前的块茎贮藏是马铃薯加工的关键环节之一。本试验以克新1号和冀张8号为试验对象,在0-180d的贮藏时间内对其干物质、淀粉、还原糖、硬度以及淀粉特性进行定性和定量研究,并建立他们之间的相关性分析。结果表明,贮藏期间干物质和淀粉的变化呈极显著正相关,但是与还原糖趋势相反;硬度与贮藏时间的变化呈极显著负相关;直链淀粉的变化规律与溶解度相似,与膨润度和透明度呈负相关。本文旨在为贮藏期间马铃薯的加工提供参考和借鉴。
The storage of tubers before potato processing is one of the key links in potato processing. The Kexin No.1, and Lizhang No.8 were used as material. The starch, reducing sugar, hardness and starch properties were qualitatively and quantitatively studied during the storage period of 0-180 days, and the correlation between them was established. The result shows： There was a significant positive correlation between dry matter and starch during storage, but contrary to the trend of reducing sugar. Hardness was significantly negatively correlated with storage time. The regularity of amylose is similar to solubility, and negatively correlated with swelling degree and transparency. The experiment was conducted to provide reference for the processing of potato during storage.
