The feasibility of esterification of phytosterol with amino acid L-Glutamic was established. The influence of various organic solvents was investigated and n-butanol was selected as an ideal solvent for phytosteryl esters synthesis with L-Glutamic. The reaction conditions were further optimized by orthogonal experiments and that 92.3% degree of esterification was obtained when operated in optimum conditions. FT-IR spectrum, GC-MS and NMR analysis were adopted to determine the steryl esters of L-Glutamic. The FT-IR spectrum indicated the presence of the ester bonds existed in the phytosteryl esters with L-Glutamic, and based on the detailed mass spectrography analysis, GC-MS and NMR offered an efficient and reliable way to confirm the steryl esters. This novel synthesis approach of phytosteryl esters with amino acid supplied a promising alternative of the substrate on esterification of phytosterols and thus can be readily applied to further studies of functional food ingredients of phytosteryl esters. |
