摘要：

This study present the preparation of potato starch film with glycerol as a plasticizer through a solution casting technique. The effect of mixing temperature (80 degrees C, 85 degrees C, 90 degrees C and 95 degrees C) on the tensile and microstructure properties of potato starch film was investigated. Results shows that the increase of temperature from 80 degrees C to 85 degrees C caused the increase in tensile strength. Nevertheless, as the temperature increase to 95 degrees C, the tensile strength and elongation at break decreased, with the highest value of 2.6MPa and 15.7mm respectively. Both of tensile strength and elongation at break were recorded for starch film prepared at 85 degrees C. Besides, the microstructure of the starch films showed gradual smoother surface, homogenous and grain growth, as the mixing temperature increased. Overall result shows that mixing temperature significantly influenced the properties of the potato starch films.
