Blanching increases the TO content of potato chips as
well as decreases the frying temperature to attain a given
moisture content in the product. The TO content was
formed mostly by PSO, secondly by STO and finally by
SO. Almost all of the TO content was absorbed by the
potato chips in the first few minutes of frying. Oil absorption
in potato chips is mainly a surface phenomenon which
mostly takes place when the chips are removed from the
fryer (during the cooling process). CLSM and SEM allow
studying the surface topography of potato chips, and in
some cases, the oil location on the surface.
