JORGE, Neuza and LUNARDI, Vanessa Martins. Influence of the oil type and frying time on the moisture loss and oil absorption by potatoes chips. Ciênc. agrotec. [online]. 2005, vol.29, n.3, pp. 635-641. ISSN 1413-7054. http://dx.doi.org/10.1590/S1413-70542005000300019.
The objective of this study was to determine the influence of the oil type and the frying time on oil absorption and moisture loss by potato chips. Sliced potatoes were fried in sunflower, corn or soybean oils, at 175ºC, for 10 minutes and different times. Samples of potatoes were analyzed for moisture and lipid contents after 1, 5, 10 and 15 fryings. Analysis of variance and Tukey test were applied to the experimental data at 1 and 5% level of significance. It was verified that the soybean oil resulted in smaller absorption by the potatoes, in comparison with the other oils studied, and higher moisture contents in the fried potatoes. Regarding lipid contents, potato chips fried in sunflower and corn oils didn't differ significantly.
