REVIEW OF RELATED LITERATURE
The researcher uses potato as the main component of making bioplastic. Potato (Sulanum tuberosum) is a starchy root vegetable of Central American Origin. It is one of the most widely grown root- crops all over the world and also an example of tuber. It belongs to perennial subspecies of Sulanum tuberosum, in the Solanaceae family. Potato plant bears many tubers underground and grows about 12 to 8 inches in height. Usually, these tubers have round to oval oblong shape but vary widely in size. The importance of this is that some people will have an idea that Potato …show more content…

When the application demands a cheap way to dispose of the item after it has fulfilled his job, biodegradability should therefore be regarded as an additional functionality. Its renewability, good oxygen barrier in the dry state, abundance, low cost and biodegradability are the advantages of starch for plastic production. The longstanding quest of developing starch- based biodegradable plastics has witnessed the use of different starches in many forms such as native granular starch, modified starch, plasticized starch and in blends with many synthetic polymers, both biodegradable and non- biodegradable, for the purpose of achieving cost effectiveness and biodegradation respectively. In this regard, starch has been used as fillers in starch- filled polymer blends, thermoplastic starch (TPS) (produced from the combination of starch, plasticizer and thermomechanical energy), in the production of foamed starch and biodegradable synthetic polymer like polylactic acid (PLA) with varying results.

Physically, glycerin is a water-soluble, clear, almost colorless, odorless, viscous, hygroscopic liquid with a high boiling point. At low temperatures, glycerin tends to supercool, rather than crystallize. Water solutions of glycerin resist freezing, a property responsible for glycerin’s use as permanent antifreeze in cooling systems. Except in very high concentrations when a dehydrating effect is noted, it is virtually nontoxic in the digestive system and non – irritating to the skin and sensitive membranes. It has a warm sweet taste and also it is odorless (The Soap and Detergent Association,
