Abstract: (6702 Views)
For investigation of potato starch properties , six potato cultivars were grown in Agricultural Research Field of Gorgan in 1381-2. Starches were extracted from these tubers and their physico-chemical properties were investigated in comparison with wheat starch. Dry matter and starch content and starch yield of potatoes were found to vary from 17.2–22, 10.6–14.6 and 9.2-12.6 % (on fresh weight basis) and the maximum and minimum of these values related to Concord and Deraga varieties, respectively. No significant difference was found at reducing sugars among fresh potatoes., Phosphorus content, viscosity and mean particle size were different among cultivars and were higher wheat starch , but amylose and protein content had no significant difference in potato starches whereas protein content of wheat starch was higher than potato starches.
