ASSESSMENT OF THE PHYSICOCHEMICAL PROPERTIES OF SELECTED OILS

The saponification value (Koettstorfer number), acid value were determined for various oils with a comparative view. As we know oils are major food factor, which is needed for human body.These oils are found in market with different brand names having good quality but some of these branded oils are liable for adultration. Therefore, we have conducted some test to explore some oils quality. From the acid value, the percentage of free fatty acid (FFA) was calculated while from the saponification value give an idea about the amount of NaOHneeded to make sodium salt of soaps.
