Biotransformation of grape pomace from Vitis labrusca by Peniophora albobadia LPSC # 285 (Basidiomycota)

Changes of the Anthocyanins and Antioxidant properties of Concord Grape (Vitis labrusca) Pomace After Acid Hydrolysis

Grape pomace contains high levels of valuable antioxidants such as anthocyanins and phenolic compounds that help prevent chronic diseases such as cardiovascular problems and cancers. In this study, Concord grape pomace was soaked in acidic solutions at different time intervals and pHs in a water bath at 80 o C. Five kinds of anthocyanins were released and identified in the pomace after acid hyd...

Optimization of supercritical fluid extraction of bioactive compounds from grape (Vitis labrusca B.) peel by using response surface methodology

Kinetic 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...

Effects of Grape (vitis Labrusca B.) Peel and Seed Extracts on Phenolics, Antioxidants and Anthocyanins in Grape Juice

Grape peel and seed are good sources of important bioactive components such as phenolics, anthocyanins and antioxidants. Recovery of these components and their proper utilization is important for the development of functional foods. We have utilized the extracts of grape peel and seed obtained by ultrasonic-assisted (UAE) and supercritical fluid extractions (SFE) for the enrichment of Campbell ...
