Q. Explain the Purity Tests of sesame oil?

Purity tests for oils/fats would include analyzing the samples for the presence of sesame oil, cottonseed oil, linseed oil, argemone oil, hydrocyanic acid, mineral oil, mobile oil, groundnut oil, kusum oil or the presence of animal fats in vegetable oils. However, we will be covering only a few considering their feasibility in the laboratories.

Test for the presence of sesame oil

The development of pink colour with furfural solution in the presence of hydrochloric acid (HCl) indicates the presence of sesame oil. This test is also known as BAUDOUIN Test. Generally this test is also used to check adulteration in the sample of ghee. The test results should be positive for vanaspati and negative for all other samples of ghee, oils and fats.
