Bioplastics are polymers derived from renewable biomass sources, reminiscent of starch, cellulose and lignin for the plant in addition to casein, proteins and lipids for the animals. The aim of this examine to find out the characterization of avocado seed and decide the impact of chitosan and ethylene glycol on the physicochemical properties of bioplastics from waste avocado seed. Avocado seeds can be utilized as a uncooked materials for starch bioplastics. Starch which is a uncooked materials for bioplastics extracted from the seeds of avocado, then characterised to find out its chemical composition. Evaluation was additionally carried out FT-IR (Fourier Rework InfraRed), SEM (Scanning Electron Microscope) and RVA (Fast Visco Analyzer) within the avocado seed starch. Manufacture of bioplastics refers to weiping band strategies, which carried out chemical modification of starch with the addition of plasticizers and fillers ethylene glycol chitosan. Within the manufacture of bioplastics starch composition avocado seed – chitosan used is 5: 5, 6: four 7: three, eight: 2 and 9: 1, whereas the load% ethylene glycol used is, 5%, 10%, 15%, 20%, 25% and 30%. The heating temperature of bioplastic various answer at 85 °C. The ensuing bioplastics analyzed the bodily and chemical properties like density, tensile power, elongation at break, Younger’s modulus, water absorption, FT-IR, SEM, and RVA. From the outcomes of FT-IR evaluation indicated a rise within the wave quantity 3394.72 cm-1 to 3622.32 cm-1 for the OH group. The outcomes of mechanical checks are additional supported by evaluation of scanning electron microscopy (SEM), which reveals the avocado seed starch granules have a dimension massive and bioplastics with filler and chitosan plasticizer ethylene glycol their tough fracture floor and contained little cavity. From the evaluation of the avocado seed starch obtained 16.6% moisture content material, ash content material of zero.23%, the starch content material of 73.62%, zero.07% amylose content material, amylopectin content material of 73.55%, 2.16% protein content material, fats content material 1.09%, gelatinization temperature of 91.33 ° C with a peak viscosity of 674.5 cP and the perfect situations of starch bioplastics avocado seeds obtained within the comparability of starch: chitosan (w / w) = 6: four with the addition of 5% plasticizer ethylene glycol with a density worth of zero.203 g/cm3, the tensile power of 30.213 MPa, elongation at break 5.370%, Elastic modulus 2031.326 MPa and water absorption of 53.06%.
