摘要: Abstract Potassium sorbate permeability behavior in sodium alginate films crosslinked with different Ca 2+ concentrations was examined using a diffusion cell. The were previously characterized considering thickness, water solubility, mechanical properties, vapor coefficient and degree of swelling. Different potassium an aqueous solution contact the used (from 150 to 1050 mg/L) resulting values order 10 −7 cm 2 /s. An increase concentration increased values, reflecting modifications film polymeric structure. crosslinking decreased constant from 2.45 × 10 0.78 × 10 /s when raised 2% 7%.
