Seven processing potato (Solanum tuberosum L.) cultivars were evaluated for biochemical properties, starch morphology, crystallinity and thermal properties. One-way ANOVA results indicated a significant difference in those quality properties of individual potato cultivar. Dry-matter, total starch, and reducing sugar contents were ranged in 21.34 ~ 24.88%, 15.6 ~ 18.3%, and 0.24 ~ 1.09%, respectively. Glucose and fructose contents were ranged in 1.03 ~ 5.28% and 0.59 ~ 3.69 mg/g DW, respectively. Saebong, a round-oval shape with white-fleshed potato cultivar, was higher in dry-matter and total starch contents. The cultivars of Atlantic, Jinseon, and Saebong showed lower reducing sugar contents ranged in 0.24 ~ 0.27 mg/g DW. The extracted potato starches showed a similar morphology, which was round, oval or elliptical shape with mixed sizes of large, medium and small starch granules and glossy surface with regular pattern. The X-ray diffraction patterns were a typical B-type, which was generally observed in root plants. The major crystallinity peaks were at 5.5°, 14°, 17°, 19°, and 22° in 2Ɵ. There was a positive correlation between the onset temperature (To) with dry-matter and total contents, but a negative correlation with reducing sugar, glucose and fructose contents. The variations in physicochemical and starch properties of different potato cultivars could be directly related to the use of potato, which make them useful for industrial application.

韩国开发的加工马铃薯（Solanum tuberosum L.）品种的淀粉特性，糖和热特性

七加工马铃薯（马铃薯）对L.）品种的生化特性，淀粉形态，结晶度和热特性进行了评估。单向方差分析结果表明，单个马铃薯品种的品质特性存在显着差异。干物质，总淀粉和还原糖含量分别为21.34〜24.88％，15.6〜18.3％和0.24〜1.09％。葡萄糖和果糖含量分别为1.03〜5.28％和0.59〜3.69 mg / g DW。Saebong是具有白色肉皮马铃薯品种的圆形卵形，干物质和总淀粉含量较高。大西洋，晋善和西城的品种显示出较低的还原糖含量，范围为0.24〜0.27 mg / g DW。提取的马铃薯淀粉显示出相似的形态，呈圆形，椭圆形或椭圆形，混合大小较大，中，小淀粉颗粒，表面有规则花纹。X射线衍射图是典型的B型，通常在根植物中观察到。2中的主要结晶度峰在5.5°，14°，17°，19°和22°Ɵ。起始温度（To）与干物质和总含量之间呈正相关，而与糖，葡萄糖和果糖含量降低呈负相关。不同马铃薯品种的理化特性和淀粉特性的变化可能与马铃薯的使用直接相关，这使其在工业上有用。
