Tortilla chips fried in used oil had more oil accumulated at the sut$ace than tortilla chips fried in fresh oil. The higher viscosity and/or lower sur$ace tension of the used oil could cause the oil to adhere to the product’s su$aces. Results showed that only 2070 of the total final oil content was absorbed by the tortilla chips duringhing, and 64% during cooling, leaving only 3670 at the chip’s surface. 0 1997 Elsevier Science Limited
