1. IntroductionIn recent decades, the growing environmental awareness hasencouraged the development of biodegradable materials fromrenewable resources to replace conventional non-biodegradablematerials in many applications. Among them, polysaccharidessuch as starches offer several advantages for the replacement ofsynthetic polymers in plastics industries due to their low cost,non-toxicity, biodegradability and availability (Fajardo et al., 2010;Simkovic, 2013). Corn has been the main source of starch commer-cially available. Other minor sources include rice, wheat, potatoand cassava and starchy foods such as yams, peas and lentils(Bergthaller, 2005).Starch is composed of amylose and amylopectin with rela-tive amounts of each component varying according to its plantsource As an example, cornstarch has about 28 wt.% amylose ascompared to cassava starch with 17 wt.%. Film-forming, barrierand mechanical properties, as well as processing conditions, aredependent on amylose to amylopectin ratio. In general, an increas-ing amount of amylose improves the abovementioned properties∗
