Some plant growth regulators, including ethephon, can stimulate abscission of mature grape berries. The stimulation of grape berry abscission reduces fruit detachment force (FDF) and promotes the development of a dry stem scar, both of which could facilitate the production of high quality stemless fresh-cut table grapes. The objective of this research was to determine how two potential abscissi...

Antioxidant potency of Indian grape cultivars varying in their skin color, seed and polyphenol content (Bangalore blue, Pandhari sahebi, Sharad seedless and Thompson seedless) and their components (whole grapes, pulp with skin and seeds) was examined as 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity using electron spin resonance spectrometry. The total polyphenols in Indian g...

Grapes and raisins provide phenolic antioxidants, which contribute to their potential health benefits. The objectives of this study were to compare the antioxidant capacity and phenolic content of green Thompson seedless grapes (the most common variety of grapes consumed in the United States), sun-dried raisins, and golden raisins (both produced from Thompson seedless grapes) and to observe the...

Utilization of grapes for juice concentrate production is an important market for grape growers in the San Joaquin Valley. Approximately 536,000 tons of grapes were crushed during the 2001 season for juice concentrate production. The majority of fruit crushed for this purpose was from Thompson Seedless cultivar, In addition, red cultivars such as Royality and Rubired were also used to produce h...

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...

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...

abstract this experiment was carried out to determine the effects of proline and ascorbic acid on chilling injury, electrolyte leakage, lipid peroxidation, peroxide hydrogen and antioxidant enzymes activity of thompson grape (vitis vinifera l.) fruit. grape fruits were treated by 0 (control), 250 and 500 µm proline and 0 (control), 2 and 4% ascorbic acid and their combinations, then stored at 1...
