using iodine to measure saturated fat

[gabi w]

hi science buddies expert!
i have a science project due next week and i am testing the saturated fat levels in a few different oils. this experiment was taken off your website because the tincture 7% iodine was declared some sort of drug in america, however i managed to source a couple of bottles from my chemist and i would like to know how to proceed with my experiment. your help would be greatly appreciated, thanks for your time!

Hello gabi w,

Sorry that we don't have the project description now. The same experiement can be found in several places on the web, such as http://www.education.com/science-fair/a ... d-testing/. Please follow all the safety notes.

okayy thank you!
do you know any other easy/medium experiments that i could use to test different cooking oils?

Hi gabi w,

This might be on short notice, but have you heard of oil strips? http://www.allqa.com/Oil_Testers.htm and http://www.allqa.com/aqa1175-6.htm

I'm sure you could compare different cooking oils with them, although they are more for the purpose of checking the extent to which the oils are broken down. I am not sure if you had any other type of experimental question in mind, but this could be a starting point. Hope this helped!
