The diffraction efficiency, sensitivity, and storage life of methylene blue-sensitized poly(vinyl chloride) film was improved by the addition of an electron donor in the matrix. The addition of pyridine enhanced the diffraction efficiency by two times, and storage life of the gratings was increased to 2-3 days.

  This study was aimed to investigate effects of aqueous citric acid (CA) and ascorbic acid (AA) on lipid oxidation in comparison with effect of vacuum packaging in order to find better treatment to delay improper changes in the Persian sturgeon (Acipenser persicus) fillets during frozen storage due to lipid oxidation. In this study traditional packaging, vacuum packaging, ascorbic acid solutio...

To meet the increasing demand for value-added fresh cod loins in the EU retail market, it is important to develop new technologies and preservation methods to effectively extend the shelf-life and improve the eating quality of fresh cod loins. The aim of this study was to investigate the effects of combined application of MAP and superchilled storage on the shelf-life extension of fresh cod loi...

fruit browning and tissue softening due to damages during handling, quality losses and water loss are the major limiting factors reducing postharvest life of early ripening apples. in this study, the effect of salicylic acid (sa) on fruit quality of apple cv ‘golabe-kohanz’ during postharvest life were investigated. harvested fruits were immersed in zero, one, two and four mm sa and were mainta...

this study investigated of antibacterial and antioxidant activity of garlic and lemon extract (1.5 %) on the quality and shelf life of fillet, vacuum-packaged rainbow trout (oncorhynchus mykiss) during refrigerated storage. were studied by monitoring the microbiological (totalviable count, psycrotrophic), chemical (tba), ph and sensory changes for a period of 20 days in (0, 5, 10, 15 and 20). e...

lighvan cheese is one of the most popular iranian cheeses that always faces to microbial problems due to traditional ways of production. in this study the effect of two types of low density polyethylene-nanocamposite films contains of ag, cuo and zno nanoparticles with different percentage increasing the shelf-life of chesse in 4̊c was investigated. microbial tests of the packed cheeses were don...

In this study traditional packaging, vacuum packaging, ascorbic acid solutio...

In the present study, effects of edible coatings using sodium alginate (SA) and sodium alginate in combination with ascorbic acid (AA) on the shelf-life extension of strawberries at 4±1°C was studied. A factorial experiment was performed based on a randomized complete block design with four replications. The treatments included control (distilled water), SA (1%, 2%, 3% w/v), SA in combination w...

Understanding the relationships between biochemical contents and morpho-phenological aspects of a plant during life cycle would be helpful for doing precise agricultural practices through its cultivation. In the present study, various biochemical parameters were evaluated in relation to bulb storage, shoot growth and florogenesis in Iranian lily (Lilium ledebourii var. Kelardasht Salehi1). Ten ...
