Characterizing Physicochemical Properties of Enset Starch

Characterization of a new biodegradable edible film based on Sago Starch loaded with Carboxymethyl Cellulose nanoparticles

Objective(s): Biodegradable film is widely used because it is free from synthetic substances and does not lead to environment pollution. This study aimed to prepare and characterize biodegradable sago starch films loaded with Carboxymethyl Cellulose nanoparticles. Methods: Sago starch films were prepared and plasticized with sorbitol/ glycerol by t...

Effect of Using Cold Plasma Treatment on the Surface and Physicochemical Properties of Starch-chitosan Composite Film

Background and Objectives: Cold plasma is an eco-friendly and non-thermal technique, which has become an important technology to change the physical and chemical features of polymers. Recently, cold plasma has been considered in the decontamination and modification of packaging materials in the food industry. Therefore, the objective of this study was to survey the effect of using low-pressure ...

Physicochemical Properties of Rice Starch Modified by Hydrothermal Treatments

Cereal Chem. 84(5):527-531 Rice starches of long grain and waxy cultivars were annealed (ANN) in viscosity peak heights, lower setbacks, and greater swelling consistency. excess water at 50°C for 4 hr. They were also modified under heat-moisThe modified starch showed increased gelatinization temperatures and tore treatment (HMT) conditions at 110°C with various moisture contents narrower gelati...

Photochemical Reactions in Polymeric

Photochemical reactions have been examined in relation with the physical properties of the solid polymeric matrix in which they are carried out. Three main reaction types are considered: (i) photocrosslinking reactions resulting from cyclodimerization of unsaturated groups and from the decomposition of photolabile groups into very reactive species, e.g. nitrenes from azides; (ii) photoisomeriza...

Characterization of nanostructured SnO2 thin film coated by Ag nanoparticles

Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...
