Physico-chemical properties of groundnut oil and their blends with other vegetable oils

Pandurangan M. K., Murugesan S

Abstract

Groundnut oil was blended with other edible oils such as palm oil and rice bran oil for the enhancement of its market acceptability. The physico-chemical properties like viscosity, density, specific gravity, refractive index, conductivity, optical rotation, acid value, saponification value, iodine value and peroxide value of vegetable oils and their blends in 95:5 to 85:15 proportions were evaluated. The result of the present study will help the oil producing industry to find out the most economically viable oil blends for cooking purposes, with maximum nutrition as well as desirable physico-chemical properties.
