Starch based nanocomposites in active packaging for fresh fruits

Starch based packaging materials are made from cassava starch with increased antimicrobial activity of titanium dioxide (TiO₂) and zinc oxide (ZnO) nanoparticles. Researchers at Chiangrai Rajabhat University in Thailand evaluated the variation of mixture ratio of starch:vinegar:glycerin:water for starch based films and studied the effect of concentrations of TiO₂ and ZnO on their antimicrobial activity.
The starch based films mixed with 0.01% w/w of TiO₂ resulted in an extended shelf life of bananas from 5-7 days to 14 days and tomatoes from 7-10 days to 21 days. An article about the research is published in the Walailak Journal of Science and Technology (WJST).
