Vacuum frying is a popular technique for snack food processing. Due to associated lower frying temperature, vacuum frying has many advantages compared to typical deep-fat frying, such as reduced oil absorption, preservation of natural color and flavor of fresh fruits, as well as loss minimization of vitamins and minerals. Consequently, a number of researchers have investigated optimum vacuum frying conditions and quality of snack products in recent years. These include apples, potato chips, and other types of fruits and vegetables.
