۱Macrobeads Based–Polysaccharides: Development and Morphological Analysis
اطلاعات انتشار: World Applied Sciences Journal، بيست و دوم،شماره۵، ۲۰۱۳، سال
تعداد صفحات: ۶
Various polysaccharides such as sodium alginate, pectin and kappa–carrageenan were studied in aqueous solution. Zeta potential and particle size were determined on these suspensions as a function of pH. Macrobeads were developed after extrusion and gelation of the polysaccharide suspension into a calcium chloride bath. SEM photographs showed that the macrobeads of alginate offered better guarantees morphological (no crack or fracture, homogeneous surface). These macrobeads may find applications in many fields such as encapsulation of bioactive compounds.
