Bioplastics are plastics that easily degraded in nature, which can minimize their potential as pollutants. It is mainly made from agro-polymers such cellulose and starch. Starch sugar palm (Arenga pinnata) has the gelatinization principle requires bioplastic raw materials by adding glycerol chitosan. This research aims to determine effect of addition chitosan composition variation on mechanical...

Saccharomyces cerevisiae cells were entrapped in matrix of alginate and magnetic nanoparticles and covalently immobilized on magnetite-containing chitosan and cellulose-coated magnetic nanoparticles. Cellulose-coated magnetic nanoparticles with covalently immobilized thermostable α-amylase and chitosan particles with immobilized glucoamylase were also prepared. The immobilized cells and enzymes...

This work describes the development of a biodegradable matrix, based on chitosan and starch, with the ability to form a porous structure in situ due to the attack by specific enzymes present in the human body (alpha-amylase and lysozyme). Scaffolds with three different compositions were developed: chitosan (C100) and chitosan/starch (CS80-20, CS60-40). Compressive test results showed that these...

Research has been carried out on the effect of chitosan composition physical and biodegradable properties areca nut nanofiber composite films with castor oil as a plasticizer. Samples were made using solution casting method. The variations used 0 g, 0.56 0.7 0.84 1.4 g one sample starch variation chitosan. samples tested thickness test, FTIR test FESEM test. Mechanical tests include tensile str...

This review article presents the recent advances in syntheses and applications of nanocomposites consisting of graphene derivatives with various polysaccharides. Graphene has recently attracted much interest in the materials field due to its unique 2D structure and outstanding properties. To follow, the physical and mechanical properties of graphene are then introduced. However it was observed ...

There has been a spreading attention in the present day to develop environmentally friendly materials such as biodegradable starch films with antimicrobial properties for food protection. Chitosan exhibited activity against wide range of microorganisms which provided great potential be used packaging material prolong shelf life products. The chitosan some food-borne pathogens were investigated....

This report shows the performance of composite biodegradable film from chitosan, starch and sawdust fiber. The main objectives of this research are to fabricate and characterize composite biodegradable film in terms of morphology and physical properties. The film was prepared by casting method. Sawdust fiber was used as reinforcing agent and starch as polymer matrix in the casting solution. The...
