in recent years immense interest has been focused on the use of solar dryers especially when taking into consideration economical and ecological aspects and increasing in fuel costs. the aim of this study was to compare the qualitative factors of raisins made by five different drying methods. at the first step, pretreatments were applied to grapes (var. sultanas) and then the grapes were dried ...

raisin is one of the most important agricultural products in iran. iran after the turkey and america countries is the third largest exporter of raisin in world. using the indices of export advantage, import advantage, concentration ratios and the herfindahl-hirschman, have been analyzed to check the state trade and market structure of export and import of raisin product in the world during 2001...

AuNPs are being conventionally synthesized by traditional methods (physical and/or chemical) with preferred and well-defined morphology, size shape. On the other hand, it has been reported that these involve difficult reaction conditions toxic chemicals. In this study, an easy, cost effective more environmentally biological-friendly method was described for synthesis of gold nanoparticles Dimri...

Grapes and raisins provide phenolic antioxidants, which contribute to their potential health benefits. The objectives of this study were to compare the antioxidant capacity and phenolic content of green Thompson seedless grapes (the most common variety of grapes consumed in the United States), sun-dried raisins, and golden raisins (both produced from Thompson seedless grapes) and to observe the...

Biomolecule-mediated nanoparticle synthesis has recently the gained attention of researchers due to its ecofriendly and non-toxic nature. Metabolites from plant extracts represent a better alternative to chemical methods to fulfill the growing demand for non-hazardous nanoparticle synthesis routes. Selenium and its nanoparticles have an extensive range of applications. Thus, biofabrication of s...

abstract comparative advantage is an economic term which is used to compare potential and actual production capacity of a country in a given commodity with the rest of the world. therefore, researches in this field could have a dual approach. in one hand it could demonstrate country’s production capacity in the production of commodities that are not produced yet and in the other hand it can ill...
