Lipid oxidation and carotene content changes in fried dough containing carrot powder during storage at 60 degrees C in the dark were studied. Flour dough containing carrot powder at 0%, 10%, 20%, or 30% was fried in 160 degrees C soybean oil and stored in a 60 degrees C incubator in the dark for 12 d. As storage time of the fried dough increased, conjugated dienoic acids and p-anisidine values of the fried dough increased. Addition of carrot to the dough lowered CDA and PAV of fried dough during storage and improved the lipid oxidative stability of the fried dough in the dark. Carotenes in the fried dough containing carrot powder were decomposed during storage, and faster decomposition rate was found in the dough containing less carrot powder.
