Coating segments with an edible alginate film utilizing a calcium salt hardener provided sufficient calcium to effectively firm soft, late season segments (Table VI). Calcium supplied by the hardener increased segment firmness 54%, and membrane shear, 50% over controls. An additional 5% calcium in the hardener further increased segment firmness and membrane shear over control values, by 89 and 85%, respectively. 

Other properties of algin reported include conductivity (252 253), contact angles of various solvents on different metal alginate films 175), depolymerization rates for alginic acid in various acids (251, 25U, 255), a pK of 2.95 for the dissociation constant of alginic acid in normal potassium chloride solution (208), absorption spectra of algin (202), and properties determined in connection with molecular weight studies, such as sedimentation and diffusion velocity and partial specific volumes (209),...

A system composed of a poly(L-lactide)acid(PLLA) asymmetric membrane combined with an alginate film was prepared. The PLLA membrane functioned to both support the alginate film and separate the soft tissue, while the alginate film was intended to act as a potential vehicle... 

Among the entire potential nanocomposite precursors, those based on layered silicates have been most widely researched probably because the starting clay materials are easily available and environmentally friendly, due to their low cost, and because their intercalation chemistry has been studied for a long time [25], Biopolymer-clay nanocomposites are a new type of materials, which are prepared by adding low amounts of clay (1-5%) to the biopolymer matrix [26]. Montmorillonite is the most commonly used natural clay and has been successfully applied in numerous nanocomposite systems [13], Some studies have reported amelioration of mechanical properties, thermal stability, water absorption, and electrical, rheological, and morphological properties of alginate films via the incorporation of nanoclay into polymer matrices [27],...
