STUDI KUALITAS MINYAK GORENG DENGAN PARAMETER VISKOSITAS DAN INDEKS BIAS

Abstract

Palm oil is one of people’s daily need. Our community is plural with different economic class. There are some community that use palm oil only once, there are also some community that use palm oil repeatedly. The aim of this research is knowing the quality of palm oil that had not been used, once used, and twice used with physical parametric. Viscosity and refractive index are used as physical parametric in this research. Viscosimeter Ostwald was used to measure the viscosity. Refractive method in prism was used to measure refractive index. Viscosity and refravtive index was carry out in room temperature. Analysis of the quality of palm oil based on viscosity measurement and refractive index showed that palm oil that had not been used was the highest value and the palm oil that was twice used was the lowest value.
