Question

How do you test for vanaspati in ghee?

Answer 1

Take about one tea spoon full of melted sample of Ghee with equal quantity of concentrated Hydrochloric acid in a stoppered test tube and addto the extract a 2% solution of freshly distilled furfural in 95% ethyl alcohol. Shake for one minute and let it for five minutes. Development of a permanent pink colour indicates the presence of sesame oil (alternatively vanaspati) in ghee.
