| Abstract:
Yellow onion contains high concentrations of flavonoids, especially flavonol quercetin glucosides. These compounds has been proposed to have beneficial health effects possibly mediated by their antioxidative properties. Lifting stage, curing and drying conditions and subsequent storage and handling probably affects the flavonoid content of onions. Preliminary results show that there is a potential to improve flavonol content in onions by using good drying and curing techniques. There is also a potential for keeping the content of flavonols during storage at 0C for up to five months. | |
