Abstract

Objective: The aim of present study was to investigate the effects of PVK as fillers on the characteristics and properties of sagu starch solution, water vapour permeability and UV-VIS transmission of the sagu starch. Material and methods: The sagu starch filled with PVK was homogenized and incorporated into sagu starch solutions at different concentrations.  Introduction of PVK fillers to sagu starch solutions significant increased the viscosity of the solution. Results and conclusions: Solubility to different solvents, moisture content was decreased. The sagu starch solutions filled with PVK nanoparticles had 30% UV transmittance.  These properties suggest that the prepared biocomposites has the potential as filler in starch based products for use as active materials in packaging and in pharmaceutical and textile industries.
