Differential thermal analysis of milk proteins. [PDF]

open access: yesAgricultural and Biological Chemistry, 1976
Differential thermal analysis (DTA) was used for study of milk protein denaturation. Protein solutions produced an endothermic peak of characteristic shape and temperature of peak minimum. The peak minimum is considered the coagulation temperature of the protein.The influence of pH and additives such as sugars and NaCl was clearly observed on the ...
