Abstract
In this study, casein, lactose, full fat milk powder and cheese powder were selected which have a great importance in food formulations. The caking, powder flow rate dependency test as well as the wettability, solubility, bulk and tapped bulk density and morphological structure was determined. The solubility, wettability, bulk and tapped bulk density and Carr index values of the samples were in the range of 2.87-58.72%, 1.15-60.00 min, 0.49-0.60, 0.58-0.71 and 11.01-22.00%, respectively. Whereas milk powder was identified as the sample with the lowest moisture and average particle size in the Carr index, it was determined as the product with the highest average particle size in terms of the solubility rate. Casein determined with the lowest solubility and wettability values was found as the product with the highest average particle size. Among samples, lactose was the only sample which caking phenomenon was determined as the sample with the longest wettability.
