A novel edible coating based on Aloe vera gel obtained according to SP Patent Filed 200302937 has been used as a means of preservation to maintain the quality and safety of cv. Crimson Seedless table grapes during cold storage and subsequent shelf life. Table grapes have a crucial economic value as a dessert fruit, but once harvested show a reduction of shelf life due to a rapid loss of quality...

In previous study, dense and homogenous 20wt% HAP/Ti composite coatings were successfully deposited on Ti substrates by cold gas dynamic spray technique. The results revealed that the phase composition of the HAP in the deposit is identical to that of the precursor powder and the bonding strength of the deposit is comparable/better to that of the plasma sprayed HAP. A relatively higher corrosio...

introduction: essential oils are used as flavoring agents in various foods. layer-by-layer (lbl) technique is a method in which the material is dipped into a series of different solutions containing oppositely charged polyelectrolytes. the aim of this study is to investigate the effectiveness of a multilayered edible coating with an antimicrobial compound (lemon and peppermint) in enhancing the...

The osmotic dehydration causes water removing from food and also a soluble solid uptake into thefoodstuffs. However, large penetration of solute into the food becomes a major problem in osmoticdehydration.Pre-coating the food to be dehydrated with an artificial, edible barrier was also explored as a wayto efficiently hinder solute penetration. In this study the effect of edible coating (CMC),co...

Calcium silicate (CS) ceramic is a good coating candidate for biomedical implants to improve biocompatibility and accelerate early osseointegration. However, the poor fracture toughness and wear resistance of this ceramic material restricts the long-term performance of implants. In this study, graphene plates (GPs) were used as reinforcement to improve the mechanical properties of CS coating. C...

A gradient composite coating on the surface of titanium materials, which are used in dental implants, is prepared using an electric-chemical method. The physical properties of the composite coating and its strength of combining with titanium material are studied by the scanning electron microscope, energy dispersive spectrum and X-ray diffraction analysis, etc. The results show that the nanohyd...

Collagen and apatite were coprecipitated as a composite coating on poly L-lactic acid (PLLA) in an accelerated biomimetic process. The incubation solution contained collagen (1 g/L) and simulated body fluid with 5 times inorganic ionic concentrations as human blood plasma. The coating formed on PLLA films and scaffolds after a 24-h incubation was characterized by using energy-dispersive X-ray s...

this study prepared new edible composite film by blending kefiran with whey protein. the film-forming solutions used different ratios of kefiran to whey protein (70/30, 50/50, 30/70, 10/90) and were cast at room temperature. the effects of the addition of whey protein on the physical, mechanical and water-vapor permeability (wvp) properties of the film were investigated. it was found that an in...

Two coatings have been developed for petrochemical compressor antifouling and corrosion resistance purposes. One is a multilayer composite coating with a modified polytetrafluoroethylene (PTFE) impregnated organic topcoat, which gives it superior antifouling performance to the similar coating that has been used by the compressor original equipment manufacturers (OEMs). The other is a high-phosp...

in the present study, ni-p-cnt composite coating was successfully fabricated via electroless plating. scanning electron microscopy (sem) was used to characterize the coatings. the effect of cnts concentration in the bath on its content in the composite coatings was studied. furthermore, the corrosion behaviour of the coatings with different contents of cnts was evaluated using tafel polarizatio...
