High amylose starch is a potential material to produce biodegradable films with the better physical properties than normal starch. In this research, Taguchi’s design and analysis of variance were used to compare the effects of gelatinization methods, starch concentrations, and plasticizers on physical properties of high amylose starch films. The results showed that the gelatinization method was the most significant factor for transparency, and the highest transparency was obtained through high temperature-high pressure treatment.
In the present study, Taguchi design coupled with ANOVA were employed to compare the importance of gelatinization method, starch concentration, and plasticizer on physical properties of HASFs. Gelatinization method had the biggest influence on transparency; starch concentration was essential in controlling thickness, tensile strength, elongation at break, and solubility in oil; the effect of plasticize on solubility in water was maximum. The information obtained from this study is helpful to choose optimal control parameters for producing HASF with desired properties.
