Analysis of thermal degradation of palm oil by dispersive Raman spectroscopy Wallace Alfredo Travassos Jr., Jefferson de Souza, Marcos Tadeu Tavares Pacheco, Landulfo Silveira Jr.

Abstract

The article deals with the analysis of the termal degradation of the palm oil heated and maintained at a temperature adjusted between 140 ºC and 160 ºC, during 90 min, by Raman spectroscopy in the wavenumber range from 800 cm^-1 to 1800 cm^-1. The alterations were identified in the peaks of β-carotene, suggesting strong degradation after 90 min of heating.
