Lipid oxidation and carotenoids in frying oil and carrot-added dough during frying were studied. Flour dough containing carrot powder was sheeted at 0.1 cm thickness and was then cut to squares to be fried. Each frying was performed in 160°C soybean oil for 1 min and repeated every 20 min for 20 h. Carrot in the dough decreased significantly the oxidative stability of frying oil and fried dough (p < 0.05). Carotenoid content in frying oil increased as frying was repeated due to dissolution of carotenoids from the dough containing carrot; however, there was no significant difference in carotenoid content among the dough fried in the oil with different number of fryings.
