Abstract

This research work deals with incorporating the potato starch to make biodegradable packaging film using glycerol as a plasticizer. Starch is a very well known carbohydrate polymer, and plants from which it is obtained grow in nearly all the temperate zones. The experiment was conducted at Department of Processing and Food Engineering, College of Agricultural Engineering and Technology, Junagadh Agricultural University during 2019-20. The experiments were aimed to prepare a biodegradable plastic from renewable sources such as starch that would be environment-friendly. Optimization of preparation condition would help us to study the feasibility and potential of this starch with other additives to obtain a biodegradable as well as high tensile strength plastic. Development of starch film was carried out at different levels of starch concentration (5, 6.5, 8, 9.5 & 11) W/V % and glycerol concentration (0.5, 0.875, 1.250, 1.625 & 2) V/V % whereas distilled water 100 ml and acetic acid 1 ml

Conclusion

Biodegradable plastics have been successfully produced from potatoes using the aforementioned approach and experimental procedures. The plastic samples produced were characterized in order to determine their physical and physico-chemical properties. Based on the results obtained, it could be concluded that the potatoes which are available in large quantity or it is a good source of starch for the production of biodegradable plastics. Their renewability and minimization of environmental pollution/hazards are of great achievement. The moisture content of the film was increase with increased the starch and glycerol content. This behavior could be explained because increasing the starch content promotes the formation of more hydrogen bridges and plastic containing glycerol absorb more moisture which is likely due to the hydrophilic nature of glycerol. Transparency of the film was decreases with increase in the starch concentration and glycerol concentration due to more molecules of starch
