The effect of water and citric acid on sago starch bio-plastics

Starch is a biodegradable polymer produced in abundance from many renewable resources. In this research, bio-plastic starch (BPS) was produced from melt processing of Malaysian sago starch with the additions of glycerol as plasticizer and water as well as citric acid (CA) as a secondary additive. Th...
