- Abstract
- The electrical conductivity of milk at various dilutions was measured at different temperatures from; 2 to 70 degrees C The results showed that dilution has only, a small influence on the temperature dependence of conductivity. A simple power-law model predicts that the conductivity is proportional to the milk concentration to the power of 0.84 and a two-term model describes the temperature dependency. The overall model has a standard deviation of 0.0067 mS cm(-1), which corresponds approximately to 0.1% milk at 2 degrees C and 0.07% milk at 70 degrees C. It was further shown that for less than about 25% milk in water Kohlausch's law and the Dekve-Huckel-Onsager theory can be used to describe the relationship between the concentration,... (More)
