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...
UV irradiation was known as an important factor for skin cancer and also textile fibers and dyes degradation. UV rays have high energy photons degrading dyes and fibers causing fading and rotting of textiles when they are exposed to sunlight. The sun blocking properties of a textile are enhanced when a dye, pigment, delustrant, or UV absorber is present which absorbs UV radiation and releases h...

AbstractIn the last step of desolvation method for preparation of albumin nanoparticles, glutaraldehyde (GA) is added to stabilize the newly formed nanoparticles. Due to undesirable effects of GA, the objective of this study was to evaluate alternative methods of crosslinking including ultraviolet (UV) irradiation, adding of glucose and combination of both methods. The nanoparticles were prepar...
The application of edible coatings is one of the most innovative methods to extend the commercial shelf-life of fruits and vegetables by acting as a gas barrier. In this study, the effects of chitosan, thymus essential oil and their combination in extending shelf life of grape (‘Bidaneh Ghermez’) and quality properties were investigated. Grapes were harvested when were fully ripened and their t...
