Edible coatings were prepared with 1% (w/v) chitosan (CH) incorporated 0.05%, 0.25%, or 0.5% tea seed oil (TSO). The physicochemical properties and antifungal ability on Botrytis cinerea (B. cinerea) of the films investigated. CH TSO applied to preserve pears (Pyrus pyrifolia Nakai) then fungal decay, respiration rate, other characters determined throughout storage at 25 °C 85 ± 5% relative hum...

The formulations contained different acrylate monomer with different structure and functionalities and TiO2, were applied to obtain pigmented acrylic films by UV exposure. The conversion and mechanical characteristic were correlated. The results showed that there is a significant interaction between pigment, reactive diluents’ type and mechanical properties of coatings. It seems that cured film...

This paper evaluated the internal stresses of different diamond and diamondlike carbon DLC coatings. For the diamond coatings, the stresses were determined using micro-Raman spectroscopy and x-ray diffraction XRD , while the stresses of DLC films were determined with bent plate method. The internal stress was related to the structural properties of the coatings. Direct current plasma jet, combu...

Edible coatings, including green polymers are used frequently in the food industry to improve and preserve quality of foods. Green defined as biodegradable from biomass resources or synthetic routes microbial origin that formed by mono- multilayer structures. They technological properties without compromising quality, even with purpose inhibiting lipid oxidation reducing metmyoglobin formation ...

BACKGROUND Highly hydrophobic surfaces can have very low surface energy and such low surface energy biological interfaces can be obtained using fluorinated coatings on surfaces. Deposition of biocompatible organic films on solid-state surfaces is attained with techniques like plasma polymerization, biomineralization and chemical vapor deposition. All these require special equipment or harsh che...

The impact of phytopathogenic microorganisms in several crops causes significant losses agrifood industry, spoilage throughout food chain and storage. Nanoparticles plant extracts have been highlighted by their antimicrobial properties applied packaging, agriculture, drug delivery systems other medical approaches. Over the past few years, this group studied application ZnO nanoparticles agroind...

In this paper the influence of material composition on the structural, surface and optical properties of HfO2-TiO2 mixed oxide coatings was investigated and discussed. Five sets of thin films were deposited using reactive magnetron sputtering: HfO2, TiO2 and three sets of mixed HfO2-TiO2 coatings with various titanium content. The change in the material composition had a significant influence o...

This study investigated the electrophoretic deposition (EPD) of the natural polymer zein combined with bioactive glass (BG) particles. Through the deposition of various BG compositions, namely 45S5 BG and Cu-doped BG, this work sought to demonstrate the ability of the films to potentiate the formation of hydroxyapatite (HA) in contact with simulated body fluid (SBF). Following incubation in SBF...

Using biodegradable films is increasingly growing since they contain natural materials. In this study, sago starch and carboxymethyl Cellulose (CMC) were used in film preparation. Sago starch films with 0, 5, 10, 15 and 20% CMC concentrations were prepared using solvent casting method. The mechanical properties were determined according to standards of American Society for Testing and Materials...
