Abstract

A healthy lifestyle based on an organic diet appears to be a growing trend among young adults. Organic soybean oils are an alternative to conventional oils, but they can be the subject of fraud that worries consumers, traders, and producers. The results obtained indicate that the combination of steady-state fluorescence techniques, considering mainly the characteristics of the spectra obtained with excitation at 320, 340 and 460 nm and time-resolved fluorescence with excitation around 403 nm, demonstrates the potential to differentiate oils conventional from organic soybeans oils.
