Formation of calcium alginate gel capsules: influence of sodium alginate and CaCl2 concentration on gelation kinetics.
The formation kinetics of calcium alginate gel capsules is studied. An increase in the concentration of alginate gives rise to a reduction in membrane thickness, while an increase in the concentration of calcium chloride leads to the formation of a thicker film. Experimental data are adjusted to the binomial diffusion equation.
