Abstract

In comparison with calcium caseinate, delactosed nonfat dry milk has a greater particle size but also a higher bulk density, reflecting the differences in their composition and physical structure. Particles of delactosed nonfat dry milk were bigger than those of nonfat dry milk as a result of swelling and aggregation. The particle size was shown not to be correlated with the bulk density. The differences in particle characteristics between delactosed nonfat dry milk and nonfat dry milk were caused by the removal of lactose producing highly porous particles. The particles of delactosed nonfat dry milk were observed to be much more irregular, rough, hollow, fragile, and swelling as a result of solvent treatment.
