The dietary consumption of grape and its products is associated with a lower incidence of degenerative diseases such as cardiovascular disease and certain types of cancers. Most recent interest has focused on the bioactive phenolic compounds in grape. Anthocyanins, flavanols, flavonols and resveratrol are the most important grape polyphenols because they possess many biological activities, such...

We overview the GRAPE-6 project, a follow-up of the ter-aaops GRAPE-4 project. GRAPE-6 will be completed by 1999-2000 and its planned peak speed is 200 TTops. Its architecture will be largely similar to that of GRAPE-4, which is a specialized hardware to calculate the gravitational interaction between particles. The improvement in the speed will come mainly from the advance in the silicon semic...

Grapes are one of the most widely grown fruits and have been used for winemaking since the ancient Greek and Roman civilizations. Grape seeds are rich in proanthocyanidins which have been shown to possess potent free radical scavenging activity. Grape seeds are a complex matrix containing 40% fiber, 16% oil, 11% proteins, and 7% complex phenols such as tannins. Grape seeds are rich sources of f...

Grape metabolites can be affected by many extrinsic and intrinsic factors, such as grape variety, ripening stage, growing regions, vineyard management practices, and edaphoclimatic conditions. However, there is still much about the in vivo formation of grape metabolites that need to be investigated. The winemaking process also can create distinct wines. Nowadays, wine fermentations are driven m...

The aim of this research is to improve an existing low-cost and simple but consistent culturing technique for measuring the adsorption of grape skin pigments on yeasts, comprising: (i) growing yeasts in Petri dishes on chromogenic grape-skin-based medium, (ii) photographing the yeast biomass, (iii) measuring its red, green, and blue colour components, and (iv) performing the statistical analysi...

The salinity of soils and water for irrigation is a limitation that influences the productivity crops has increased worldwide af fects morphology physiology plants since it causes osmotic stress ionic toxicity impairs absorption nutrients. ef fect salt on some morphological physiological traits in Coccoloba uvifera (L.) L. (sea grape) seedlings from dif ferent origins was evaluated whose behavi...

The skins and seeds of grapes are known to be rich sources of phenolic compounds, both flavonoids and non-flavonoids. The aim of the present study is to determine polyphenolic composition, antioxidant potential along with free radical scavenging activity and antimicrobial properties of ethanol extract of Grape skin and seed. Grape seed showed high antioxidant and antimicrobial activity compared...

Background Grape pomace (GP) is a by-product of wineries after filtering the grape juice for wine production. GP contains seeds, pulp, skin, and stalks with acidic properties, it normally composted before using as soil amendment. However, composting requires more time, labor, equipment; furthermore, loses some desirable organic acids arid soils. The properties these plant nutrients in make amen...

grape, like other horticultural products due to high humidity, low relative ph and wealth of nutrients, is subjected to attack by pathogenic fungi during the harvest and storage stages. in this study, at first, the some post-harvest pathogenic fungi of grape were isolated in meshgin-shahr and two fungal species including botrytis cinerea and cladosporium cladosporioides were identified as the d...

Infusions and extracts of different grapes inactivated poliovirus; agents responsible for this property resided in the skin of the grape. Commercial grape juice at both natural and neutral pH inactivate various enteric viruses and herpes simplex virus; a 1,000-fold reduction in poliovirus infectivity occurred after incubation with grape juice, pH 7.0, for 24 h at 4 degrees C. A variety of wines...
