Abstract:
This study was designed to determine the extent of removal of pork, beef and chicken fat from food grade belting with water when temperature and pressure were the experimental variables. For pork fat, no significant difference was observed between water temperature of 40 and 55°C, whereas at 25°C less fat (P<0.05) was removed regardless of pressure. Significantly more beef fat was removed at 40°C and the intermediate pressure than at 40°C and either the higher or lower pressure. For chicken fat, pressure was the only significant variable, with no interaction between pressure and temperature. The higher the pressure, the more chicken fat was removed. Overall, temperature was a more important variable than pressure. The data imply that temperature of the washing solution should be above the melting point of the type of fat to be removed.

States of Water
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
