Multivariate near infrared spectroscopy models for predicting the oxidative stability of biodiesel: Effect of antioxidants addition

► We report the use of NIRS to determine the oxidative stability of biodiesel. ► The models cover a large calibration range (from 0.43 to 22 h). ► We analyze the effect of the addition of antioxidants on NIRS models performance. ► NIRS can be used as a simpler/faster technique to determine the oxidative stability of biodiesel.
