Esterification of potato starch with oleic acid in the presence of lipase from Candida antarctica in a microwave field and under conventional heating
Abstract
An attempt has been made to prepare hydrophobic, thermoplastic material through esterification of potato starch with long-chain unsaturated fatty acid. The esterification was conducted in the presence of fungal lipase from Candida antarctica immobilized on apolymer carrier. Reaction was conducted in amicrowave field and, for comparison, under conventional heating. The completion of the esterification reaction was confirmed by spectroscopic FT-IR and 1H NMR methods, X-ray powder diffraction and scanning electron microscopy (SEM). It was found that the obtained product exhibited higher hydrophobicity than native potato starch.
