Many product variables such as food composition,
product shape, surface to weight ratio and porosity affect
the final fat/oil content of fried product. A linear
relationship exists between the surface area and the fat/
oil content (Gamble & Rice, 1988). If the surface is
rough, overall surface area increases and the result is an
enlarged oil uptake.
Frying oil quality has also a certain influence on oil
absorption and therefore on the organoleptic and nutritive
characteristics of fried food products. That is attributed
to formation of oil degradation compounds (high
molecular weight polar compounds) which increased the
polarity of the frying medium. Consequently, the oil
