The influence of multi stage alginate coating on survivability of potential probiotic bacteria in simulated gastric and intestinal juice

“…Alginates are natural hetero polysaccharides made up of D-mannuronic and L-guluronic acid residues joined linearly by (1-4)-glycosidic linkages (Smidsrod, Haug, & Lian, 1972). Alginate beads can be formed by both extrusion and emulsion methods (Krasaekoopt, Bhesh, & Deeth, 2003).…”

The influence of coating materials on some properties of alginate beads and survivability of microencapsulated probiotic bacteria

“…Microencapsulation of probiotics has been investigated for improving their viability in food products and the intestinal tract (Rao, Shiwnarain, & Maharaj, 1989). The most widely used encapsulating material is alginate, a linear heteropolysaccharide of d-mannuronic and l-guluronic acid extracted from various species of algae (Smidsrod, Haug, & Lian, 1972). Alginate beads can be formed by both extrusion and emulsion methods (Krasaekoopt, Bhandari, & Deeth, 2003).…”

Algal Walls — Composition and Biosynthesis

“…In the gels prepared by diffusion of calcium chloride into sodium alginate solutions (SMIDSROD et al 1972, SMIDSROD and the counterions would all be calcium. In the plant, however, the alginate is in equilibrium with seawater and is combined principally with calcium, magnesium, and sodium (HAUG 1964, HAUG andSMIDS-ROD 1967), and it is logical to suppose that it is in the form of a gel with the calcium ions being concentrated in G-blocks, largely in junction zones, the other ions being associated with other parts of the alginate molecules.…”
