BACKGROUND Pears are exported in large quantities from South Africa, resulting in large revenues. Minimisation of quality losses once the fruit has reached the export destination is as important as following strict export and distribution protocols. Kafirin can form edible films. In this study an edible coating made from 20 g kg(-1) kafirin coating solution was applied as a postharvest treatmen...

The aim of the present study was to investigate the impact of whey protein coating on quality and shelf life of Kilka fish. Whey protein edible coating was prepared in three different concentrations, including 3, 7, 10 and 13%. Then gutted Kilkas were coated for 1h, packed in polyethylene dishes with cellophane blanket and stored at -18 °C. Total microbial count, total volatile nitrogen (TVN) a...

Background and Objectives: Production and consumption of freshly-cut fruits have been increased in recent decades.  One of the major problems in storage of freshly-cut fruits, the color change, is a result of the oxidative reactions of phenolic compounds by polyphenol oxidases. Various treatments such as coating and refrigeration are used to improve quality and shelf-life of the fresh-cut fruit...

Edible coatings can improve the quality of fresh, frozen, and processed meat, poultry, and seafood products by retarding moisture loss, reducing lipid oxidation and discoloration, enhancing product appearance in retail packages by eliminating dripping, sealing in volatile flavors, functioning as carriers of food additives such as antimicrobial and antioxidant agents, and reducing oil uptake by ...

Oxidative and microbiological degradations are the main factors that determine the quality of food and the shelf life. Color and moisture stability are important quality attributes that contribute to meat shelf life, salability and consumer acceptability. There is currently considerable interest in edible films coatings and natural antioxidants because of their potential to improve the quality ...

Surface modification on Mg alloys is highly promising for their application in the field of bone repair. In this study, a new metal-organic framework/MgF₂ (Mg-MOF-74/MgF₂) composite coating was prepared on the surface of AZ31B Mg alloy via pre-treatment of hydrofluoric acid and in situ hydrothermal synthesis methods. The surface topography of the composite coating is compact and homogeneous, an...

In this study, functionally graded Ni-Al2O3 composite coating (FGN-A) has been produced from nickel Watt’s bath containing different concentrations of Al2O3 particles. For this, different composite coatings were electroplated in the same bath with different particles concentration to find the optimum concentration of particles in which the maximum content with uniform distribution of Al2O3 part...
