• Crust & moist interior foods are produced by
high-temperature frying.
• Rapid crust formation is beneficial in that it seals
moisture into the food but restricts rate of heat
transfer to the interior.
• The bulk of food retains a moist texture & flavour
of the ingredients.
• Foods which are dried by frying are processed
at a lower temperature to cause the plane of
evaporation to move deeper inside the food
before the crust forms.
• Methods of commercial frying: shallow frying &
deep-fat frying
