Our approach is adapted from individual based modeling concepts, using the notion of fundamental building bloc – the grid cell, defined as the lowest volume/surface of the ...

The most important PUFAs have at least two double bonds placed on the carbon chain. These include ?-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahaxaneoic acid (DHA). Microencapsulation is a technique used to protect the bioactive compounds from oxidative damage, to ensure their controlled release and to activate the synergistic effect of the ingredients, if it exists. In this context, the microencapsulation process of fish oils rich in PUFAs using alginate was studied, in the presence and the absence of an ultrasonic (US) field. Both BoxBehnken design of experiment technique and the Response Surface Method were used, to investigate the influence of the process parameters and to optimize the operating conditions. The operating parameters under inve...
