Simultaneous allergy to vine pollen and grape.
We report the case of an 18-year-old female student suffering from seasonal rhinoconjunctivitis with sensitization to pollens from vine and also from grass, olive, and Chenopodiaceae plants who had recently developed episodes of itching, maculopapular rash, and facial angioedema after eating grapes. Testing revealed positive reactions to vine pollen and grapes, and specific IgE were found for b...
متن کاملAntioxidant effects of grape vine cane extracts from different Chinese grape varieties on edible oils.
This study involved the determination of the peroxide value (POV) as a measure of the resistance of the oxidation of edible oil with grape vine cane additives to assess their antioxidation potential. The study demonstrated that grape extracts of canes could effectively inhibit the lipid oxidation of edible oils and that this ability varied significantly due to the different extraction solvents ...
متن کاملOptimization of NIR Spectral Data Management for Quality Control of Grape Bunches during On-Vine Ripening
NIR spectroscopy was used as a non-destructive technique for the assessment of chemical changes in the main internal quality properties of wine grapes (Vitis vinifera L.) during on-vine ripening and at harvest. A total of 363 samples from 25 white and red grape varieties were used to construct quality-prediction models based on reference data and on NIR spectral data obtained using a commercial...
متن کاملProducing Quality Grape Juice
INTRODUCTION The first grape juice known to be processed in the United States was produced by Dr. Thomas B. Welch, a New Jersey dentist, in 1869 with the newly developed pasteurization process. Assisted by his wife and their 17-year-old son, Charles, he extracted juice from 18 kg (40 lb) of grapes (Vitis labrusca L.). They filtered and bottled the juice and pasteurized it in hot water to kill t...
متن کاملCopper impacts on grape berry cells: uptake and detoxification
Copper has been extensively used as the active principle of fungicides, since the late 1800s when the “Bordeaux mixture” was developed and its spectacular efficiency proved against fungal pathogens such as downy mildew, which is a large threat to winegrowers. Although initially it seemed to improve plant growth in unproductive lands, repeated use of copper-based fungicides has led to the accumu...
