Starches from four processing type potato varieties, cultivated in two locations in Hokkaido prefecture of Japan were evaluated for the effects of variety and growing locations on their physicochemical properties. Amylose and phosphorous contents, average granule size, solubility, swelling power, thermal and pasting properties were evaluated. Pearson's correlation analysis and two-way ANOVA were applied and found that significant differences in amylose content, phosphorous content and average granule size were observed among the four varieties and between the two locations (p < 0.05). Swelling power and pasting properties were higher in starches from Kamikawa, while solubility was higher for starches from Tokachi. Higher T0 and TP observed for Kitahime in Kamikawa and T0, TP and TC for Andover and Snowden in Kamikawa suggest presence of more stable crystalline structures in starch granules grown in Kamikawa. Thus, variety and growing locations affected the starch properties, such as thermal and pasting properties significantly (p < 0.05).
