Nano-encapsulation of isolated lactoferrin from camel milk by calcium alginate and evaluation of its release
2015
Abstract Lactoferrin is a glycoprotein, playing several biological roles. The main goal of our work was to nanoencapsulate the isolated lactoferrin from camel milk through alginate nanocapsuls. We studied the influence of alginate concentration (0.2 and 0.5 w/w%) and encapsulation method (thermal vs. non-thermal treatment) on the encapsulation efficiency, zeta potential, particle size and release of lactoferrin from nanocapsuls. Our results revealed in 0.8 and 0.9 M NaCl fractions, lactoperoxidase was present. So these fractions were not passed to further experiments. On average, we measured the lactoferrin content to be 0.5 g/l within the original camel milk. In general, higher alginate concentration resulted in higher encapsulation efficiency and nanocapsuls prepared with thermal treatment had a higher efficiency (almost 100%) along with smaller particle sizes (mostly
