Metabolism of nonesterified and esterified hydroxycinnamic acids in red wines by Brettanomyces bruxellensis.
While Brettanomyces can metabolize nonesterified hydroxycinnamic acids found in grape musts/wines (caffeic, p-coumaric, and ferulic acids), it was not known whether this yeast could utilize the corresponding tartaric acid esters (caftaric, p-coutaric, and fertaric acids, respectively). Red wines from Washington and Oregon were inoculated with B. bruxellensis, while hydroxycinnamic acids were mo...
متن کاملGreen approach for the synthesis of pyranopyrazoles and hexahydroquinoline-3-carboxamides using unripe grape juice (verjuice) as catalyst
Unripe grape juice (verjuice) as a natural catalyst was successfully applied to perform the one-pot reaction of aryl aldehydes, malononitrile, hydrazine hydrate and ethyl acetoacetate to synthesize pyranopyrazole derivatives in aqueous ethanol at room temperature in excellent yields. Furthermore, unripe grape juice catalyzed one-pot synthesis of hexahydroquinoline-3-carboxamide derivatives by t...
متن کاملThe Effects of Unripe Grape Juice on Lipid Profile Improvement
Introduction. Consumption of unripe grape juice (verjuice) has been portrayed by the traditional belief, as a means of combating dyslipidemia. We aimed to evaluate the effects of unripe grape juice consumption on lipid profile in healthy human volunteers. Methods. We asked 42 enrolled volunteers to drink 10 cc of verjuice within 30 minutes to 2 hours after lunch and 10 cc of it after dinner. Af...
متن کاملBacterial antimutagenesis by hydroxycinnamic acids from plant cell walls.
We have determined the abilities of (E)-ferulic acid, (E)-p-coumaric acid and (E,E)-5-5-dehydrodiferulic acid to protect against different types of mutation in a simple bacterial model. These antimutagenic properties were compared with those of the related compound curcumin, and also with those of an extract containing hydroxycinnamic acids obtained by the saponification of the cell walls of wh...
متن کاملKinetic Modelling for Flavonoid Recovery from Red Grape (Vitis vinifera) Pomace with Aqueous Lactic Acid
This study was undertaken with the aim of establishing a correlation between the extraction yield in total flavonoids from red grape pomace and the extraction temperature, using 0.5% (w/v) aqueous lactic acid as the solvent system. Extraction of flavonoids was found to obey second-order kinetics, and on such a basis, the yield in total flavonoids at saturation could be very effectively determin...
