Abstract

Peanut oil is widely used in the health care as a carrier for active substances, mainly in topical applications, but its use can pose risks to individuals allergic to the grain. Since ozone and ultrasound are two tools with the potential to cause changes in the molecular structure of the oil, this work aims to evaluate through Raman spectroscopy molecular changes in peanut oil submitted to ozonation and ultrasound. The principal component analysis (PCA) showed changes in the Raman spectra, mainly degradation of the bonds of the methyl and methylene groups and creation of carbon double bonds, and formation of ozonides. Such changes may reduce the allergenic effect of peanuts and contribute to the use of peanut oil in new therapeutic applications.
