Abstract

This work is aims to synthesize a novel stearic acid (SA) grafted N,O-carboxymethyl chitosan (NOCC), and then use it as a wall material to nanoencapsulation macadamia oil. The grafted copolymer is a amphiphilicity sample. By the catalysis of 1–(3-dimethyl amino propyl)-3-ethyl carbodiimide hydrochloride (EDC•HCl) and N-hydroxy succinimide(NHS), we got hydrophilic and hydrophobic NOCC-SA polymers via the condensation reaction between the carboxyl of arboxymethyl chitosan and the carboxyl of stearic acid in a water bath. Macadamia oil has significant effect on whitening and spotting, also as a bioactive compound with health beneficial potential, which are used as safe additives in food , medicine, cosmetics. However Macadamia oil is sensitive to light, thermal condition and oxidation. Nanoencapsulation could be an adequate technique to overcome these challenge. Here, we obtained the analysis by scanning electron microscope and grainsize analyzer that most nanocapsules sizes ranged from 130.2 to 200.8 nm. To sum up, this study showed that amphiphilic chitosan were a kind of potential carrier. It could increase the solubility of hydrophobic substances and make it sustained release by nanoencapsulation.
