raisins are dried grapes that may be eaten raw or used in cooking, baking and brewing as an ingredient. iran is one of the major exporters of raisins in recent years and iranian raisins are exported to many countries. it is important to ensure of microbiological quality and safety of raisins. the aim of this study was isolation and identification of mycoflora from main raisin’s varieties (poloi...

the sorption isotherm and state diagram of sundried, golden and sultana raisins were constructed for investigation and comparison of the product stability. the isotherms were measured at 15, 25 and 35 °c using an isopiestic method and the data were modeled with gab model. glass transition temperatures of the products were measured by differential scanning calorimetery (dsc) and fitted to gordon...

This study aimed to determine individual phenolic compounds of common produced Turkish raisins. As material, Sultan 7, Antep Karasi and Razaki raisins were used. The HPLC method was performed for the analysis 11 compounds. major acid trans-caftaric flavan-3-ol also (+)-catechin. varied between 21.56 46.84 µg/g in samples (+)-catechin 2.21 74.12 µg/g. Caffeic second most abundant with 11.06-21.5...

Solar dryer technology is simple and can be implemented by households small communities due to its simplicity. The suitable design of the absorber/collector very vital for any solar drying system as collector efficiency plays a key role in determining overall efficiency. To study practical applicability developed dryer, grapes were dried chamber designed comparison, open sunlight. Faster was no...

From 1990 through 1992, nematodes were extracted from soil samples taken from the rhizosphere of native species of grapes from four areas of northern California and two areas of southern California. For comparison, samples from domestic grapes as well as a putative hybrid of Vitis califarnica and V. vinifera were also taken. Rhizosoil from California native grapevine contained many more species...
