Abstract: Two endothermic peaks could be observed for five commercial s les of bovine serum albumin (BSA). The smaller peak observed by differential scanning calorimetry (DSC) corresponded to enthalpy relaxation. This peak was followed on storage of BSA, in its glassy state, after it had been heated above its denaturation temperature. Enthalpy and peak temperature increased with duration of storage. On storage for one week at 60 degrees C, a s le at 8.3% moisture showed a peak at 100 degrees C with an energy value of approximately 2 J per g protein. BSA s les were heated within the DSC sufficiently to eliminate the lower enthalpy peak but without altering the denaturation enthotherm. The amount of physical aging shown by these BSA s les was similar to that of the heat-denatured s les. It was concluded that the heating endotherms of dry BSA reflect both the storage and thermal history of the s le. Possible implications of the enthalpy relaxation of BSA on the behavior of this important protein are considered.
