THE EFFECT OF CARBON DIOXIDE REMOVAL UPON THE FREEZING POINT OF VACUUM TREATED MILK

Abstract
Vacuum treatment of fluid milk by non-steam injection flavor removal equipment has been shown to elevate the freezing point of milk when the equipment is operated at low levels of flash-cooling. This study indicates that the loss of carbon dioxide, at the reduced pressures employed for the vaporization of volatile flavor components, is a prime factor responsible for the freezing point elevation. The implications of the effects of carbon dioxide loss on the freezing point of milk are discussed.
