One of the methods to reduce oil absorption in fried products is partial drying before frying. In this study, influence of partial drying （10 min, 20 min, 30 min） on oil absorption and quality attributes of three potato cultivars （Agria, Satina, kenebek） was evaluated. Our results reveled that in Agria, partial drying leads to an increase in oil absorption compared with non-dried sample （p〈0.05）. In kenebek, partial drying reduced the oil absorption and improved the texture and color of the produced French fries （p〈0.05）. Similar results were observed with Satina as with kenebek. In all three varieties, partial drying increased the dry matter, color quality and required cutting force of the French fries （p〈0.05）.展开更多
