Physical-Chemical Characterization of OzonizedCoconut Oil

摘要

In the present study, the products from the ozonation of three systemsrn(ozonized coconut oil, ozonized coconut oil with water and ozonizedrncoconut oil with ethanol) are characterized and compared statistically.rnPeroxide, acidity and viscosity indexes were determined. The reactionrnproducts were identified by 1H NMR and their antimicrobial activityrnwas evaluated. The ozonized coconut oil with ethanol showed thernhighest peroxide and acidity indexes. This result suggests that inrnpresence of ethanol a greater peroxide decomposition occur leading torngreater acid formation. The variation coefficients obtained in thernanalysis methods were smaller than 10%. As reaction products werernidentified ozonides and aldehydes compounds. The highest actionrnspectrum of antimicrobial activity by Staphylococcus aureus wasrnobtained with the ozonized coconut oil with water and ethanol systems.
