effect of Plasticizer type and concentration on physical properties of biodegradable films based on sugar palm arenga pinnata starch for food packaging
Journal of Food Science and Technology-mysore, 2016Co-Authors: Muhammed Lamin Sanyang, S.m. Sapuan, Mohamad Ridzwan Ishak, Mohammad Jawaid, Jaafar SahariAbstract:In this study, sugar palm starch (SPS) films were developed using glycerol (G), sorbitol (S) or their combination (GS) as Plasticizers at the ratio of 15, 30 and 45 (wt)% using casting technique. The addition of Plasticizers to SPS film-forming solutions 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. On the contrary, density and water absorption of plasticized films decreased with increasing Plasticizer concentration. Raising the Plasticizer content from 15 to 45 % showed less effect on the moisture content and water absorption of S-plasticized films. Films containing glycerol and glycerol-sorbitol Plasticizer (G, and GS) demonstrated higher moisture content, solubility and water absorption capacity compared to S-plasticized films. The results obtained in this study showed that Plasticizer type and concentration significantly improves film properties and enhances their suitability for food packaging applications.

Effect of Plasticizer type and concentration on physical properties of biodegradable films based on sugar palm (arenga pinnata) starch for food packaging
Journal of Food Science and Technology, 2015Co-Authors: Muhammed Lamin Sanyang, S.m. Sapuan, Mohamad Ridzwan Ishak, Mohammad Jawaid, Jaafar SahariAbstract:The use of starch based films as a potential alternative choice to petroleum derived plastics is imperative for environmental waste management. This study presents a new biopolymer (sugar palm starch) for the preparation of biodegradable packaging films using a solution casting technique. The effect of different Plasticizer types (glycerol (G), sorbitol (S) and glycerol-sorbitol (GS) combination) with varying concentrations (0, 15, 30 and 45, w/w%) on the tensile, thermal and barrier properties of sugar palm starch (SPS) films was evaluated. Regardless of Plasticizer types, the tensile strength of plasticized SPS films decreased, whereas their elongation at break (E%) increased as the Plasticizer concentrations were raised. However, the E% for G and GS-plasticized films significantly decreased at a higher Plasticizer concentration (45% w/w) due to the anti-plasticization effect of Plasticizers. Change in Plasticizer concentration showed an insignificant effect on the thermal properties of S-plasticized films. The glass transition temperature of SPS films slightly decreased as the Plasticizer concentration increased from 15% to 45%. The plasticized films exhibited increased water vapor permeability values from 4.855 × 10−10 to 8.70 × 10−10 g•m−1•s−1•Pa−1, irrespective of Plasticizer types. Overall, the current study manifested that plasticized sugar palm starch can be regarded as a promising biopolymer for biodegradable films.
