Effect of low oxygen storage on carbohydrate changes in onion (Allium cepa var. cepa) bulbs

Ernst, M. K.; Praeger, U.; Weichmann, J.

Onion (Allium cepa var. cepa; 'Sherpa', type Rijnsburger) bulbs were stored for 36 weeks at 2 degrees C under different oxygen concentrations (0.5, 1.0 and 21%). Samples were collected after 9, 18, 27 and 36 weeks of storage. Water-soluble carbohydrates, respectively fructans were analysed using anion exchange chromatography combined with pulsed amperometric detection.
