Abstract

HYDROPHOBICALLY MODIFICATION of POTATO STARCH was successfully carried out by mild esterification using acyl chlorides (octanoyl, lauroyl, palmitoyl chloride) in aqueous media, which resulted to good yields. Starch esterification was performed with long chain fatty acid chlorides (C8, C12, C16) in two steps, in the first step, starch dispersed in the reaction medium was alkali treated and the second, esterification. Samples of HYDROPHOBIC STARCH esters were synthesized with moderate degrees of substitution (DS-values<0.45) and reactivity of POTATO STARCH with this reaction conditions was studied. The chemical structural characteristics of the obtained products were investigated using common spectroscopy methods (FTIR and 1H NMR spectra). Starch nanoparticles and nanodispersion solutions were prepared via dialysis method. Particle size distribution of the nanoparticles determined with using laser diffraction particle size analyzer in aqueous dispersion. The morphology investigation of the starch and the grafted starch nanoparticles was carried out by SEM after freeze drying.
