Synthesis and Application of Starch Based Bionanocomposite

Starch is a noteworthy vitality wellspring of sustenance for mankind. It is created in seeds, rhizomes, roots and tubers as semi-crystalline granules with one of a kind properties for each plant. The fundamental parts of starch granules are two polyglucans, to be specific amylose and amylopectin. The sub-atomic structure of amylose is nearly straightforward as it comprises of glucose deposits associated through α-(1,4)- linkages with long chains . Amylopectin which is a stretched particle with a noteworthy segment, has a similar essential structure, however it has extensively shorter chains and a ton of α-(1,6)- branches. Iodine arrangement is utilized to test for starch to show of starch. Starch is normally mixed with hydrophobic biodegradable polymers to improve the materials water opposition and mechanical properties. The polymer based composites are used in various fields, starting from packaging to biomedical. The new generation biopolymer based composites containing nano fillers are called bionanocomposites. Starch and modified starches have a broad range of applications both in the food and non-food sectors. The synthesized bionanocomposite were resistant to mineral acid and alkali with little sacrifice of biodegradability.
