A novel method to find sesame oil in fats
A novel method to detect Sesame oil in other oils and fats has been developed by a young researcher Avanish Shukla. The details of the new method have been published in a prestigious International Journal of Oleo Science, Japan. The researcher has claimed that his methodology has now been widely accepted.
A novel method to detect Sesame oil in other oils and fats has been developed by a young researcher Avanish Shukla. The details of the new method have been published in a prestigious International Journal of Oleo Science, Japan. The researcher has claimed that his methodology has now been widely accepted.
He said there was only one method to detect sesame oil in other oils. The system was known as the ‘Baudouin Test’. But this test could detect the Sesame oil up to 0.2 per cent. However, the system developed by Shukla could detect the presence of sesame oil up to 0.1 per cent in other fats and oils.
Shukla said the colour test to detect the presence of sesame oil was easy to perform.
He said, “If a small quantity of sesame oil itself or sesame oil containing some other fat was allowed to react with 2-Thiophene Carboxaldehyde in the presence of Hydrochloric Acid a very fine pink or deep red colour is developed.
This colour reaction is specific to sesame oil. Other oil and fats do not give this test result at all.”
Shukla said an ordinary person can by a simple experiment can detect whether the sesame oil was mixed in an oil or fat. Explaining the test process he said, “Five ML of oil or melted fat was taken in a 25ML measuring cylinder provided with a glass stopper and was mixed with 5 ML of Hydrochloride Acid and 0.5 ML of 2 percent ethanolic solution of 2-thiphene Carboxaldehyde .
The glass stopper was inserted and the mixture was shaken vigorously for two to three minutes and later the mixture was allowed to be separated. The development of pink colour or deep red colour in the lower acid layer indicates the presence of sesame oil in other oils and fats.”
Shukla claimed that the test developed by him could be considered as an alternative to the modified Baudouim test for detecting the Sesmae oil in any other oil including Vanaspati Ghee.
The present research was done by Avanish Shukla under the supervision of an eminent oil technologist and the director of the Harcourt Butler Technological Institute Dr RP Singh.
