Infrared spectra of virgin (control), UV exposed (UV treatment) and heated (thermal treatment) SFSB oils. (A) Full FTIR of original and treated oils. (B) Resolved spectral region from 3200 to 4000 cm−1. (C) Resolved spectral region from 1550 to 1850 cm−1. (D) Resolved spectral region from1250 to 1400 cm−1. UV treatment was irradiation (254 nm); thermal treatment at 100 °C for 10 days, both under ambient atmospheric conditions.
