Quercetin content in stored onions (Allium cepa L.): effects of storage conditions, cultivar, lifting time and nitrogen fertiliser level.

The effect of storage conditions on the concentration of the anti-oxidant and anti-inflammatory glucocide quercetin in onions.

Year of Publication2007

Storage experiments with commercial cultivars of onion (Allium cepa L.) showed that cultivar differences in quercetin glucoside content were significant, but neither nitrogen fertiliser level nor lifting time had more than minor effects at start of storage or after 3 or 5 months and the content of quercetin glucosides only showed a minor reduction. Early lifting resulted in onions with low sprouting and good storage abilities without negative effects on quercetin glucoside content.
