Preparation and characterization of acetylated starch mediated silver nanoparticles: the effect of solution ratio and time-varying exposure

Plastic packaging is widely used in food industry to protect and maintain food freshness. However, plastic packaging also contributes to solid waste problem and can become the contamination area of microbial activities which in turn affecting the shelf-life of the food product and may causing food-b...
