Mechanical and barrier properties of starch blend films enhanced with kaolin for application in food packaging.
Int J Biol Macromol. 2021 Dec 01; 192:1013-1020.IJ

Abstract

Starch blend films of native cassava starch and medium distarch phosphate cassava starch (crosslinked cassava starch) were prepared by solution casting. The effects of kaolin content on the water resistance and mechanical properties of the starch blend films were investigated. The addition of 10 wt% kaolin to the starch blend film lowered water vapor permeability to 3.51 × 10-5 g m day-1 m-2 Pa-1, water solubility to 31.60% and raised tensile strength to 2.99 MPa. At this loading of kaolin, the structural integrity of the starch blend film was maintained during immersion in water and thermal stability was enhanced. Scanning electron microscopy revealed kaolin to be well dispersed and embedded within the starch matrix. In summary, the starch blend film composite with 10 wt% kaolin had interesting properties as a material to replace non-biodegradable synthetic plastics for packaging, particularly sachets for food products.
