The starch powders were extracted from fresh cassava by the cold extraction method. The yield percent of the extracted cassava starch is 14.32 %. The physicochemical properties of prepared cassava starch such as pH, moisture content, ash content and bulk density were detected. The bioplastic film was prepared by the casting method with varying amounts of starch powder, glycerol and vinegar. The physicochemical properties of prepared bioplastic films were evaluated by pH, moisture content, viscosity and specific gravity. In addition, the physicomechanical properties such as thickness, tensile strength, elongation at break percent, and tear strength of prepared bioplastic films were also evaluated. The ratios of starch, glycerol, and vinegar (3g : 0.5mL : 1mL) are the most suitable for the physicomechanical properties for the preparation of bioplastic films. The transparency, water absorption capacity, shelf life, and biodegradable ability of prepared bioplastic films were also investigated. The transparency of prepared bioplastic films was measured by using a UV-Visible spectrophotometer at the wavelength of 550 nm. The prepared bioplastic films were characterised by Fourier transform infrared (FT IR) spectroscopy. The FT IR results showed the presence of O-H, C-H, C-O-C stretching and C-O-C ring vibration in carbohydrate. The decomposition nature of prepared biodegradable film was investigated by TG DTA. The water absorption capacity of prepared bioplastic films was determined by soaking them in water for 24 hours. The biodegradable ability of selected bioplastic films was examined by soil burial test. The bioplastic film was found to be almost degraded after 12 days. The prepared bioplastic films were synthesised using natural and environmentally safe raw materials and showed biodegradation, thus proving to be a good alternative to conventional plastics."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "cassava starch"}, {"interim": "casting method"}, {"interim": "bioplastic"}, {"interim": "biodegradation"}, {"interim": "shelf life"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2024-02-12"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Cherry Aung (259 to 272).pdf", "filesize": [{"value": "653 KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 653000.0, "url": {"url": "https://meral.edu.mm/record/9298/files/Cherry Aung (259 to 272).pdf"}, "version_id": "0a6701e6-df64-4ef0-b820-469acb450e64"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "2022", "subitem_journal_title": "University of Yangon Research Journal", "subitem_pages": "259-272", "subitem_volume": "11, No. 1"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Cherry Aung"}, {"subitem_authors_fullname": "Cho Cho"}, {"subitem_authors_fullname": "Hlaing Hlaing Oo"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2022-12-31"}, "item_title": "Preparation and Characterization of Biodegradable Starch Based Bioplastic Film from Cassava", "item_type_id": "21", "owner": "12", "path": ["1582967633684"], "permalink_uri": "https://meral.edu.mm/records/9298", "pubdate": {"attribute_name": "Deposit date", "attribute_value": "2024-02-12"}, "publish_date": "2024-02-12", "publish_status": "0", "recid": "9298", "relation": {}, "relation_version_is_last": true, "title": ["Preparation and Characterization of Biodegradable Starch Based Bioplastic Film from Cassava"], "weko_shared_id": -1}
