Abstract

The investigation of processes to use oil-rich organic wastes to generate biodiesel is an important research area nowadays. In this respect, quantifying oil/fat and biodiesel with less labor demanding analytical tools such as proton nuclear magnetic resonance (1H NMR) can provide faster and more accurate acquisition of the chemical quality parameters of the organic samples. In the present study, the fat obtained from mango seed kernel (MSK) and its biodiesel were investigated using 1H NMR spectra to identify its physicochemical parameters. The results indicate that MSK fat shows high oxidative stability, and the biodiesel produced from MSK fat was compatible with European (EN 14214) and Brazilian (RANP 07/08) standards. The 1H NMR technique was efficient for providing the chemical parameters of MSK fat and its biodiesel without the need of any pretreatment. In addition, complementary analysis was performed to determine the MSK biodiesel quality.
