stability depends on
packaging. Good packaging and storage condition
extend the storage duration of chips.
Oil uptake during frying is also need to be
considered during frying because the fat content of a
product will also affect its flavour, odour and general
organoleptic properties. The frying oil not only acts as
heat transfer medium, because they are heated to high
temperatures approximately 170-180°C, it will start
to degrade through hydrolysis and oxidation of fatty
acids. The breakdown products themselves give rise
to flavour and can further react with carbohydrates,
proteins and their decomposition products to produce
taste traditionally associated with fried food. One of
the alternative used to reduce fat content in chips is
by doing a pre-treatment before frying. According
to Mai Tran et al. (2007), pre-treatment technique
will reduce the oil absorption by reduction of surface
permeability. As a food product is fried, the internal
cells become dehydrated and the evaporated water
is partially replaced by the frying oil (Rosana et
al., 1997). Besides that, Saguy and Pinthus (1995)
