BACKGROUND : An IgE-mediated allergy against a lipid-transfer protein of grapes was the cause of repeated severe anaphylaxis in a patient after consumption of grapes, wine, and raisins. OBJECTIVE : Although the patient was aware of her grape allergy, avoidance proved difficult and accidental anaphylaxis occurred. Furthermore, wine allergy in a wine-growing district means a non-negligible rest...

In order to evaluate the potential aroma of some Portuguese grapes, several glycosidically bound aroma compounds of ten grape varieties grown in Évora, Alentejo, Portugal, were released, identified and quantified using gas chromatography–mass spectrophotometry. White varieties were Arinto, Perrum, Rabo-de-Ovelha, Roupeiro and Antão Vaz. Red varieties were Trincadeira, Aragonez, Tinta Caiada, Mo...

Berry texture and berry skin mechanical properties are traits with high agronomic relevance because they related to quality parameters marketing requirements of wine, table, raisin grapes. Searching for QTLs linked texture, an F1 population 152 individuals their parents were used in this study. These plants obtained crossing Raboso Veronese, a seeded black wine grape cultivar, Sultanina, seedle...

The process related to the changes in dimensions and mass of grape berry passes through two growth phases separated by a lag phase, can be described double sigmoid curve. onset their duration are important factors for understanding processes berries. A new method quantitative determination was developed present study. In this method, phase transition dates correspond times at which rate change ...
