In the present paper an attempt has been made to evaluate the physicochemical properties(density, moisture content, specific gravity, refractive index, boiling point, viscosity, acid value, peroxide value, iodine value, saponifiation value) of some available edible oils in Tirupathi and detail description of various factors affecting edible oils like temperature, moisture, oxygen, effect of refining process, types of adulterations, effects of metals, and antioxidant properties of oils has been discussed.
Edible oils, physicochemical parameters, adulterations, anti oxidant properties, refining process
