Question

A food manufacturer is advertising a new cake mix as fat-free. Scientists at the U.S. FDA are testing the product to see if it truly lacks fat. Hydrolysis of the cake mix yields glucose, fructose, glycerol, a number of amino acids, and several kinds of molecules with long hydrocarbon chains. Further analysis shows that most of the hydrocarbon chains have a carboxyl group at one end. What would you tell the food manufacturer if you were a spokesperson for the FDA?

Answer 1

There are many molecules that are considered fats, but all contain fatty acids: long hydrocarbon chains with a carboxyl group on the end. Based on the presence of fatty acids in the mixture, I would suggest that the mix is not fat free.

Answer 2

I guess, FDA should have regulations for fat levels in flour based products because regular flour contain some amount of fats.
