Edible film is a packaging development for environmentally friendly food that composed of organic ingredients, so it safe consumption. Natural polymers make up edible films include polysaccharides, lipids, and proteins to replace synthetic materials. The characteristics good have properties like other plastic packaging, namely being easy shape, transparent, flexible, not easily damaged, cheap. ...
Background and Aim: Humic substances include natural organic polyelectrolyte materials that formed most of the dissolved organic carbon in aquatic environments. Reaction between humic substances and chlorine leading to formation of disinfection byproducts (DBPs) those are toxic, carcinogenic and mutagenic. The aim of this study was investigation of isotherms, kinetics and thermodynamics of humi...
Purpose Paper aims to evaluate the efficiency of traditional chitosan, nano and chitosan nanocomposites for consolidating aged papyrus samples. Cellulose-based materials, such as sheets paper, which are most common types writing supports works art in many museums archive. They subjected different deterioration factors that may lead conservation problems. Consolidation treatment is one treatment...
Abstract Background and objectives: In this research, the formation of chitosan-TiO2 nanocomposite and its antibacterial effect on Escherichia coli and staphylococcus aureus was investigated Material and Methods: to study the results, we used Scanning electron microscopy (SEM) and transition electron microscopy (TEM) images, infrared (IR) spectroscopy and ultraviolet-visible. Optical Density (O...
