ABSTRACT

The present investigation was carried out to determine the various physical and electrical characteristics of skim milk with respect to density, specific weight and electrical conductivity. These physical characteristics were determined considering three levels of temperatures 25, 30 and 350C at intervals of 0, 1, 2 and 3 h. The highest values for density and specific weight of skim milk were observed as1032.32 kg/m3 and 10.13 kN/m3at 250C respectively and with respect to time it was observed 1030.99 kg/m3 and 10.12 kN/m3 at 3 h respectively. The highest electrical conductivity of skim milk was 5.62mS/cm at 350C and with respect to time it was observed 5.54mS/cm at 3 h. There is not much appreciable effect of variation on physical and electrical characteristics with respect to time, whereas the temperature had shown significant effect(P<0.05) on physical characteristics of skim milk. The data generated in the present investigation can be utilized as guidelines for designing of skim milk based processing systems like evaporated plant and skim milk spray drying plant etc.
