Abstract
Density determinations of milk-water mixtures were made, to determine if the temperature of maximum density is lower than that of water and if it is less as the milk in the mixture increases. It was found that as milk was diluted with water, the temperature of a maximum density of the mixture approached that of water in a linear way, but there were deviations at some points near the maxima. Linearity between temperature at maximum density and added water, and the large difference of temperatures for maximum density of milk and water, suggest a method for determining adulteration of milk. Variations of temperature of maximum density may indicate changes in the physical state of proteins. Editor.
