Monitoring Pv In Corn And Soybean Oils By Nir Spectroscopy, Gülgün (Yildiz) Tiryaki

Dr. Gülgün YILDIZ TIRYAKI

Gülgün Yildiz a, b, Randy L. Wehling*,a, and Susan L. Cuppett a a: Department of Food Science and Technology, University of Nebraska, Lincoln, Nebraska 68583-0919, and b: Olive Culture Research Institute, Universite Cd. No. 43, Bornova/Izmir, Turkey 3500. NIR spectroscopy was used successfully in our laboratory to monitor oxidation levels in vegetable oils. Calibration models were developed to measure PV in both soy and corn oils, using partial least squares (PLS) regression and forward stepwise multiple linear regression, from NIR transmission spectra. PV can be measured successfully in both corn and soy oils using a single calibration. The most successful …
