To improve the value of grape seed, high purity methyl linoleate was prepared from grape seed oil by urea adduction. The effects of the mass ratio of fatty acid methyl ester to urea, mass ratio of urea to 95% ethanol, adduction time and adduction temperature were studied. The control urea crystal and adduction solid were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). The optimum conditions for the preparation of high purity methyl linoleate were obtained as follows: mass ratio of fatty acid methyl ester to urea 1∶ 2, mass ratio of urea to 95% ethanol 1∶ 4, adduction temperature 5 ℃, adduction time 10 h. Under the optimum conditions, the content of methyl linoleate was 94.83%, and the yield was 40.41%. FTIR and XRD analysis showed that no new functional group was formed in urea adduction, and the crystallinity of urea was reduced by the adduction of methyl linoleate. SEM images confirmed the formation of hexahedral adduction complex between urea and fatty acid methyl ester. In summary, urea adduction is an effective method for enrichment of high purity methyl linoleate from grape seed oil. |
