Effects of harvesting and drying methods on internal atmosphere, outer scale appearance, and storage of bulb onions (Allium cepa L.).

In trials carried out in As and Toten in southeast Norway, onions were harvested on various dates by traditional harvesting and field curing methods or by a cutting and direct harvesting method, and dried at various temperatures and humidities. The occurrence of translucent and leathery scales, leaf sprouting and other postharvest problems was examined after 8 months' storage at 0 deg C. Late harvesting (at about 100% leaf fall-over), high drying temperature (30 deg C), and a long drying duration produced the highest incidence of translucent scales, the highest internal CO2 levels and the lowest O2 levels. Late harvesting and prolonged field curing gave the highest occurrence of leathery scales, but the results could not be correlated to internal atmosphere. Late harvesting, high drying temperature and cuffing the leaves at harvest gave the highest degree of leaf sprouting.
