 ABSTRACT

In this study, properties of starches extracted from the three Indian varieties of sweet potatoes, Shri-Bhadra, PT-23 and Kanchengad  were  compared. Varieties  have   influence  on  starch properties which helps in  selection of the variety according to specific application. The starch yield ranged from 30.96% to 39.26%, in which, Kanchengad starch recorded highest amylose content (36.06%). The sweet potato varieties differed significantly with functional properties. Shri-Bhadra starch possessed superior values with highest water absorption capacity (0.89 ml/g), oil absorption capacity (0.82 ml/g), paste clarity (0.55%), sediment volume (2.15 ml) and bulk density (0.57 g/m3) among all the compared cultivars. Results obtained revealed that moisture, ash, protein and fat contents showed no significant difference. The study concluded that different varieties varied in starch yield, functional properties and color values but exhibited similar chemical properties.

Key words: Purple sweet potato varieties; Functional characteristics; Chemical composition
