grape is used in large amounts and different types (fresh, raisin, vinegar, molasses, juice, unriped grape and etc). remarkable amount also are preserved in stores and cold-rooms to be supplied out of season, that causes  quality and weight decrease. this research was conducted to study different factors which affect the grape shelf-life. obtaining more information about optimum conditions and ...

Polyphenols in grape and wine have been suggested to contribute to the cardiovascular health benefits of the Mediterranean lifestyle. The reported effects of grape products on blood pressure (BP) remain, however, equivocal. In a double-blind placebo controlled crossover study, the effect of two grape extracts on BP and vascular function was assessed in 60 untreated, mildly hypertensive subjects...

grapevine is one of the very important fruit crops in iran the fruit of which is used as table grape and/or raisins. in this study, some genetic parameters (phenotypic and genetic correlation, heritability and repeatability), of some important traits in table grape (date of ripening, weight, length and width of berry as well as attachment to cluster strength) were evaluated. results showed high...

Pomegranate (Punica granatum L.) peel and sumac (Rhus coriaria L.) fruit and leaf extracts were chemically characterized and their ability to inhibit table grape (cv. Italia) rots caused by Botrytis cinerea was evaluated on artificially inoculated berries. Different extraction methods were applied and extracts were characterized through Ultra Fast High Performance Liquid Chromatography coupled ...

During recent years a large annual surplus of grapes has been produced in the United States, and the development of new grape products to take care of this increasing supply is at present an important phase of the grape industry. Because of the general interest in a fruit so abundantly grown, it seemed desirable to study the nutritive value of grapes and grape juices more extensively than had p...

During ripening of grape (Vitis labruscana L. cv Concord) berries, abundance of several proteins increased, coordinately with hexoses, to the extent that these became the predominant proteins in the ovary. These proteins have been identified by N-terminal amino acid-sequence analysis and/or function to be a thaumatin-like protein (grape osmotin), a lipid-transfer protein, and a basic and an aci...

Grapevine berry development is a complex and genetically controlled process, with many morphological, biochemical and physiological changes occurring during the maturation process. Research carried out on grapevine berry development has been mainly concerned with wine grape, while barely focusing on table grape. 'Fujiminori' is an important table grapevine cultivar, which is cultivated in most ...

BACKGROUND Inflammation and pain associated with temporomandibular joint disorder, a chronic disease that affects 15% of the adult population, involves activation of trigeminal ganglion nerves and development of peripheral and central sensitization. Natural products represent an underutilized resource in the pursuit of safe and effective ways to treat chronic inflammatory diseases. The goal of ...

ABSTARCT Grape (Vitis vinifera) seed extract found to be exhibits wide range of beneficial effects insights to screen the potential compounds which includes polyphenolic compounds both flavonoids and non-flavonoids that show antioxidant effects. In this present study phytochemical screening of alkaloids, flavonoids, glycosides, polyphenol and flavonoids, tannins, and sterols were presented in t...

Objectives: To examine Plate Waste (PW) from elementary and middle school-aged children by school and by grade when grapes were on the lunch menu versus when they were absent. The primary hypothesis tested was that grapes enhance consumption and lessen plate waste, thereby serving as a “gateway” fruit to healthier eating. The foods examined were selected fruits, vegetables, and entrées. The end...
