Fruit and vegetables are heat sensitive; therefore, vacuum frying
is an alternative method to produce high quality fried products at a lower processing temperature. For example, vacuum-fried
pineapple chips obtained at 24 kPa (112 C for 7 min) had a golden
yellow color and retained total vitamin C, phenolic compounds and
antioxidant capacity with low oil uptake. Processing at low temperature and pressure reduces the amount of oil penetrating into the material and the deterioration
and oxidation of the frying oil, resulting in stable fried food products
