Abstract
The convective heat transfer coefficients during deep-fat frying of Oreochromis niloticus fillets in palm oil at different temperatures were determined. Tilapia fillets were plate-shaped cut and dipped in oil at 130, 150, and 170 °C in an electric fryer six liter stainless steel. Thermophysical properties were measured as a function of temperature and composition of the food, using the computer program DEPROTER. The convective coefficients were determined from plots of time -vs- dimensionless temperature relationships, and these decreased with increasing oil temperature, with values of 46.76, 34.61 and 32.66 W/m
