Notes:
Frozen samples were placed in one of two insulated vessels at room temperature. Enthalpy was measured by the electrical energy required to reverse the temperature differential that developed. Tests with pure ice agreed to within 0.3% of expected values. Measurements on beef, bread, egg white, and applesauce were similar to published values. The change in average enthalpy during freezing was examined and agreed with an enthalpy-based freezing model. Differential compensated calorimetry affords several advantages and was particularly useful for rapid measurement of enthalpy in commercial freezer conditions.
