Interaction of Bovine α-Lactalbumin and β-Lactoglobulin during Heating

Abstract
The degree of thermodenaturation of .alpha.-lactalbumin [cow milk] is greater when heated in the presence of .beta.-lactoglobulin than when heated by itself. This effect increases with temperature and pH (range 6.4-7.2). .alpha.-Lactalbumin interacts with an aggregated form of .beta.-lactoglobulin. .alpha.-Lactalbumin does not affect the amount of undenatured .beta.-lactoglobulin at the end of heating.
