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...

since a long time ago raisins has been considered as an exporting item iniran, in which only 15-20 percent of raisins are consumed and the remaining is exported at a low price. also, until 20 years ago,iranwas one of the most important exporters of raisins to european and asian countries. unfortunately because of retarded technology, lack of modern agricultural methods and also lack of suitable...

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 ...

The glycemic index (GI) refers to impact of the ingestion of carbohydrate-containing foods on blood sugar concentrations. High-GI foods increase blood glucose levels more and for a longer time, than those with low GIs. It appears that those who adopt a low-GI diet have a reduced risk of heart disease, type 2 diabetes mellitus, and obesity. Carbohydrate-containing foods on a low-GI diet include ...

Microwave (MW) vacuum dehydration using temperature to control the level of MW power demonstrated potential in improving the performance of the process. Product surface temperature measured by an infrared temperature sensor was used to control MW power at any level between 0 and 3 kW. Multiple linear regression analysis indicated an r2 = 0.942 for prediction of final moisture content and r2 = 0...

Traditionally, raisins have been thought to promote dental caries due to their suspected "stickiness" and sugar content. Current research identifies some evidence contrary to traditional thought, suggesting that raisins may not contribute to dental caries. This article reviews new findings with regards to raisins and the 3 conditions that are thought to contribute to the formation of dental car...

In the last years, the interest in non-alcoholic grape products, aa potential alternative sources of phenolic compounds, has considerably increased. Raisins are dried grapes largely consumed in the Mediterranean area for the positive pattern of nutrients, and for recent data describing potential benefits on human health. Among the health-promoting substances contained in raisins, flavonoids see...

To confirm our hypothesis that the sex and age of cynomolgus monkeys influences the effect of training, we employed a new training technique designed to increase the animal's affinity for animal care personnel. During 151 days of training, monkeys aged 2 to 10 years accepted each 3 raisins/3 times/day, and communicated with animal care personnel (5 times/day). Behavior was scored using integers...
