Specific heats of oils and fats
WebA. Physical changes in oil during heating and frying Deep-fat frying is a process of cooking and drying in hot oil with simultaneous heat and mass transfer. As heat is transferred from the oil to the food, water is evaporated from the food and oil is absorbed by the food (Fig. 1). Many factors affect heat and mass transfer, including WebSpecific heat capacity (c p ) is a temperature dependent physical property of foods. Lipid-being a macromolecular component of food-provides some fraction of the food's overall …
