| Abstract: |
| In order to develop solid base oil products without trans fatty acids, the physicochemical properties, fatty acid composition and microstructure of fully hydrogenated cottonseed oil were studied. The basic physicochemical indexes of fully hydrogenated cottonseed oil were determined according to the corresponding national standard methods, the fatty acid composition was analyzed by gas chromatography, the solid fat content was determined by pulsed NMR, finally, the crystal structure was characterized by polarizing microscope, differential scanning calorimetry, and X-ray diffraction. The results showed that the physicochemical indexes of fully hydrogenated cottonseed oil met the national standard for edible hydrogenated oil. Its fatty acid composition was mainly palmitic acid and stearic acid, and almost contained no trans fatty acids. The results of solid fat content showed that fully hydrogenated cottonseed oil remained solid at 40 ℃ which was suitable for compounding with liquid oil. In addition, the micromorphology of fully hydrogenated cottonseed oil was fine and dense needle, which was consistent with the β′ crystal form, and there was also a certain amount of β crystal form. The above researches showed that using fully hydrogenated cottonseed oil as transesterification blend base oil, pharmaceutical raw materials and cosmetics raw materials had a certain application and development prospect. |
