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...

Some commercial sweet sorghum syrups can be fraudulently or accidently adulterated with inexpensive sugar syrups, particularly high fructose corn syrup (HFCS) or corn syrup, and sold at a relatively low market price or even mis-branded. This undermines the economic stability of the current small-scale producers of food-grade sweet sorghum syrup as well as the developing large-scale bioproduct i...

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...

background and objectives: prunus domestica (plum) has been considered as a useful remedy for several disorders in iranian traditional medicine (itm). it has cold and wet temperament and is used as syrup for hot temperament diseases such as hot headache and stomach disorders. in the present study, plum syrup has been formulated according to itm manuscripts and quality control evaluations have b...

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...

A study has been initiated to review syrup clarification technology, with the objective of finding methods of improving syrup clarification, including chemical addition, and with special reference to aeration and flocculation problems. Preliminary results suggest that significant improvements to raw sugar quality are possible, particularly filterability. The review to-date is presented, with re...

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...
