Abstract EN
Quercetin and quercetin glucosides are the major flavonols present in onion (Allium cepa L.) and are predominantly present as quercetin, quercetin-3,40-diglucoside and quercetin-40-glucoside.
Effect of different light wavelengths on onion after harvest and storage, with fluorescent, blue, red and ultra violet light influenced the quercetin and quercetin glucosides profile.
In a peeled onion, all the light treatments elevated quercetin content in bulb.
Among them, particularly fluorescent light effect was more eminent which stimulates the maximum synthesis of quercetin in onion.
In case of whole onion bulb, skin and pulp showed different responses to light treatment, respectively.
The pulp had the highest quercetin glucosides under blue light, whereas the lowest under fluorescent light.
Onion skin showed nearly opposite pattern as compared to the pulp.
In particular, light treatment proved to be a better way to increase the level of quercetin content in onions which might be utilized for industrial production of bioactive compounds from onion and onion waste products.
