Post-harvest withering of grape berries is used in the production of dessert and fortified wines to alter must quality characteristics and increase the concentration of simple sugars. The molecular processes that occur during withering are poorly understood, so a detailed transcriptomic analysis of post-harvest grape berries was carried out by AFLP-transcriptional profiling analysis. This will ...

partial rootzone drying (prd) is a new irrigation technique which improves water use efficiency without significant yield reduction in grape. to study the effects of partial rootzone drying and green pruning on yield and yield quality of thompson seedless grape a split plot experiment with randomized complete block design and three replications was conducted. the experiment was performed in tak...

Kurdistan Rasa grape is beautiful, delicious and black in color. It has some vitamins such as E, C and some protectors such as antioxidant. In order to design equipments and facilities for the drying, preservation and processing of Rasa grape, it is necessary to know about the specific heat and thermal conductivity. Therefore, the objectives of this study were to determine the specific heat and...

In light of their environmental and economic interests, food byproducts have been increasingly exploited and valorized for their richness in dietary fibers and antioxidants. Phenolic compounds are antioxidant bioactive molecules highly present in grape byproducts. Herein, the accelerated solvent extraction (ASE) of phenolic compounds from wet and dried grape pomace, at 45 °C, was conducted and ...

Abstract Grape pomace is a rich source of bioactive compounds and dietary fiber. This study aims to valorize the grape by microwave-vacuum-assisted drying extraction, which novel, green, clean label technology. The extraction from was optimized using response surface methodology. Box-Behnken design used for three process variables, i.e., time, power, vacuum levels. highest rate observed (5.53 g...

An evacuated tube solar collector drier is designed and developed to study analytically and experimentally drying kinetics of Thompson seedless grapes in Pune, India. Drying experiments are carried out in the month of April- June for continuous three years from 2013-2015. During the experimentation, temperatures of hot and cold air at various places, ambient relative humidity and humidity varia...
