KINETICS OF WATER VAPOUR ADSORPTION BY THE MIXTURES OF MILK POWDER AND CARBOHYDRATES

The sorption properties of milk powder admixed with selected carbohydrates were examined, when studying the effects of mixture composition, agglomeration and humidity. The sorption of water vapour by milk powder, glucose, saccharose, maltodextrin and starch was found to proceed with different rates depending on the type of material, water content and humidity. The addition of 30% carbohydrates to milk considerably changed the course of kinetic curves for water vapour adsorption by the mixture, as compared with milk powder. Agglomeration of milk powder and its mixtures with carbohydrates only slightly changed the course of the kinetic curves for water vapour adsorption.
