Advances in Deep-Fat Frying of Foods

Deep-fat frying is a complex engineering process that involves heat and mass transfer between a food and its frying medium. This text explains frying process by combining engineering principles with fundamentals of biochemistry. It reviews heat and mass transfer and variations found in the physical properties of food during frying. Information about the rheological properties of batters and the effects of batters on product quality is also discussed, as are novel frying technologies employed to make fried foods healthier, such as a microwave frying and vacuum frying. The text also discusses the formation of acrylamide, a potential carcinogen formed during frying, and considers ways of reducing it.
