Enter your observations in the table provided. If a suitable slicer is available, you can prepare potato chips following steps 2 6. The appropriate frying time will depend on the thickness of the slices. The slice thickness and frying times should be the same for both potato samples. Then you can compare the color, flavor, and texture of the chips made from the refrigerated and nonrefrigerated potatoes.
Refrigeration causes the fries to be darker, possibly sweeter, and waxy in texture.
Texture differences may be too subtle to notice. It is not expected that the students would know the answer, but the question should generate a lively discussion of vegetable respiration.
