Abstract 

The protein profiles of domestic potato cultivars were evaluated for total protein determination, amino acid composition, SDS-PAGE analysis and scanning densitometry. There were statistically significant differences in the levels of amino acids among potato cultivars. Total nitrogen amount was also significantly different among cultivars, ranging from 1.27 to 1.64%. SDS-PAGE analysis showed that there were significant differences in the content of major potato proteins such as papatin (40 kDa), trypsin inhibitor (20 kDa) and protease inhibitor (15 kDa) among cultivars (p<0.05). The amount of papatin among cultivars with a range of 22.16 to 25.81 mg/g d.w. was higher in Jopung, Shepody and Superior, whereas the amount of protease inhibitors including 15 kDa and 20 kDa was the highest in Jopung (37.0%). The Shepody contains the highest amount of papatin (25.8%) and the lowest of trypsin inhibitor (5.22%). Thus, it is suggested that Shepody is the most desirable cultivar for better nutrition based on the protein profile.
