Summary

THE FOAMING CAPACITY, FOAM AND EMULSION STABILITIES OF AN OVALBUMIN SOLUTION INCREASE AFTER FREEZE-DRYING OR SPRAY-DRYING. HOWEVER, THE INTRINSIC VISCOSITY, THE QUANTITY OF SULPHYDRYL RESIDUES, THE CIRCULAR DICHROISM SPECTRUM OF THE OVALBUMIN MOLECULE AND ITS SENSITIVITY TO SUBTILISINE, VARY VERY SLIGHTLY. THE MOLECULE HYDROPHOBICITY INCREASES WITH DRYING. THE STRUCTURE OF OVALBUMIN IN SALT FREE SOLUTIONS, PREPARED WITH FREEZE-DRIED OR SPRAY-DRIED OVALBUMIN POWDER IS DIFFERENT TO THAT OF ORIGINAL OVALBUMIN.
