淀粉粒度是衡量马铃薯淀粉品质的一个重要指标。测定了5个马铃薯品种不同大小块茎淀粉的平均粒径及离散度,得出以下结论:克新13号、克新19号、克新21号块茎质量大于250 g时其淀粉的平均粒径最大,克新18号、克新20号块茎质量在150~250 g之间其淀粉的平均粒径最大;5个品种均是块茎质量小于75 g时的淀粉平均粒径最小。5个品种之间比较表明,克新20号淀粉的平均粒径最小,克新13号在块茎质量大于75 g时其淀粉的平均粒径最大。克新13号、克新18号、克新19号、克新21号在块茎质量大于250 g时淀粉的粒度分布最均匀,克新20号块茎质量在150~250 g之间时淀粉的粒度分布最均匀。
Starch size is an important indicator of the quality of potato starch. The average particle size and dispersion of tuber starch of five different potato varieties were determined. The following conclusions were obtained: the average starch diameter of tuber of Kexin 13, Kexin 19 and Kexin 21 with the mass of more than 250 g was the largest The average starch particle size of tuber of Kexin No. 18 and Kexin 20 was the highest among 150 ~ 250 g tubers. The average diameter of starch was the smallest when the tuber quality was less than 75 g. The comparison among 5 varieties showed that the average particle size of Kexin No. 20 was the smallest. The average starch particle size of Kexin No. 13 was the highest when the tuber mass was more than 75 g. The grain size distribution of starch was the most uniform when the tuber mass was more than 250 g, that of gram new No. 18, gram new 18, new ginseng 19 and new gxin 21 were between 150 and 250 g The most uniform distribution.
