Ginger (Zingiber officinale) is a globally known food and flavoring ingredient which is also reputed for its wide range of medicinal properties. The rhizome of ginger consists of a unique homologous series of compounds, gingerols, which are the major phenolic plant secondary metabolites responsible for its unique flavor and health benefits. Over the last 2 decades, extensive research has been conducted to identify bioactive constituents and medicinal potential of ginger. This review deliberates chemical composition as well as the most recent research findings on potential health benefits of ginger, including its antimicrobial, anti-inflammatory, blood pressure-lowering, cholesterol-lowering, antiplatelet aggregation, chemopreventive, antioxidant, and hypoglycemic properties.
The heat treatment of holding grape mash at 60°C for 30 minutes allowed recovery of a higher concentration of specific phenolic compounds into juice without giving caramelized flavours and odours. Physicochemical and sensory properties of four grape juice blends prepared from three selected grape cultivars, 'Castel 19637', 'Lucie Kulman', 'Sovereign Coronation' and water were evaluated on the selection for a non-alcoholic wine-like beverage. A descriptive sensory study was conducted using 18 trained panelists to assess the color, sweetness, astringency, viscosity and overall acceptability of the beverages. Overall, considering the sensory attributes, concentration of bioactive phenolics, antioxidant capacity measured by ferric reducing antioxidant capacity, and moderate sugar content, the blend of 'Castel 19637': water (3:2, v:v) was found to have more potential to be used in developing a wine-like functional beverage. 'Castel 19637', which was originally developed as a red wine grape cultivar, can be recommended as a suitable grape cultivar for developing a functional beverage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
