Effect of plasticizer on sugar palm starch films

Researchers at the Universiti Putra Malaysia developed sugar palm starch (SPS) films using glycerol, sorbitol or their combination as plasticizers. The addition of plasticizers helped to overcome the brittle and fragile nature of unplasticized SPS films.
Increased plasticizer concentration resulted to an increase in film thickness, moisture content and solubility and a decrease of density and water absorption. The results showed that plasticizer type and concentration significantly improves film properties and enhances their suitability for food packaging applications. An article about the research is published in the Journal of Food Science and Technology.
