Abstract
The present research “Technology for isolation of potato starch from non-commercial potato
varieties” was carried out with the objectives to standardize the method for isolation of potato
starch, characterization of starch isolated from commercial and non-commercial potato
cultivars and to develop value added products from isolated potato starch and to evaluate the
storage stability of developed products. Four potato cultivars namely Kufri Chipsona-3, Lady
Rosetta (commercial potato cultivars), Kufri Ganga and Kufri Pukhraj (non-commercial
potato cultivars) were procured from department of vegetable sciences, Punjab Agricultural
University, Ludhiana. Among the cultivars studied, commercial Potato cultivars KufriChipsona-3
and LR contained the highest dry matter content and lowest reducing sugar
content compared to non-commercial cultivars. Starch extracted from different potato
cultivars differ significantly (p<0.05) in their physico-chemical and functional properties.
Higher yield was obtained from commercial cultivars compared to non-commercial cultivars.
For pasting properties, starch obtained from non-commercial potato cultivars showed higher
final viscosity than commercial ones. So these were selected for the preparation of value
added potato products. (Non-cereal pudding mix and vegetable soup mix). Storage studies
showed that non-cereal pudding mix and vegetable soup mix can be stored safely for 6
months and 4 months respectively. These products are non-cereal based easy to prepare, shelf
stable products and can be consumed during the fasting period .
