From algonato short review, it seems clear that alginates are new industrial polysaccharides which may be used in many other applications than only food industry.
At end, it is important to mention the recent synthesis of well defined new biohybrid glycopolymers having guluronic oligomers grafted on a hydrophilic backbone giving also gels in the presence of calcium counterions. Cooking or warming breaded foods in a microwave oven causes a lack of crunchiness.

Alginates fibers were reinforced by introduction of hydrolysed chitosans which diffuse into the alginate fiber allowing to introduce antibacterial properties Food Hydrocolloids 25 Antibacterial films were obtained by incorporation of extruded white ginseng to ensure healthy foods Danish Medical Bulletin 55 1 The role of guluronic acid blocks GG blocks is particularly important for gel mechanical properties in presence of calcium counterions.
Conclusion From this short review, it seems clear that alginates are new industrial polysaccharides which may be used in many other applications than only food industry.
The use of cell cultures has been widely employed as part of a series of recommended tests to assess the biological behaviour of materials put in contact with human tissues Estrela, ; Jorge et al. In the present study, the cytotoxicity of dental alginates was assessed through cytotoxic tests performed with mouse fibroblast L cells, a method largely used in several works evaluating the cytotoxicity of materials for use eel dentistry Alcaide et al.

Then, the main applications in food and biomedicine are briefly mentioned followed by tentative applications in packaging, paper, textil and wound dressing which are described. Calcium alginate fibers have a novel gel-forming capability in that, upon the ion exchange between sodium ions in the contact solution and calcium ions in the fiber, the fiber slowly transforms into a fibrous gel.
Under their monovalent salt form especially sodium formalginates are perfectly water soluble and increase of solvent viscosity upon dissolution causing an interesting thickening character in relation with the semi-rigid conformation of this copolymer which found valuable applications.
Preparation sental properties of antibacterial alginate films incorporating extruded white ginseng extract. In that view, a film of alginate gel with high salt concentration was used as an edible susceptor.
Alginates applications Alginates in Foods Up to now, the main applications of alginates were based mainly on their gel-forming ability and used as food additives in jams, jellies Alginates in paper industry Alginate partially complexed with calcium such as forming a loose gel mixed with starch was proposed to get high water retention in paper coating.
Cytotoxic effect of saffron stigma aqueous extract on human transitional cell carcinoma and mouse fibroblast. To verify the cell response to extreme situations, other 3 groups were included in the study: Comparison of gels of different chemical composition.
Advanced textile materials and biopolymers in wound management. Alginates differ from each other according to the components present in their formulation.
