Abstract
The feasibility of storing onions at high temperature in the UK was investigated in a series of experiments over 4 years.
Sprouting was lower but rotting and weight loss due to desiccation were higher at 30° and 35°C compared with 20 and 25°C. Overall wastage was least at 25°C within the range 50 to 70% r.h. but totalled 50% after 9 months storage and was still high (38%) when used for a comparatively short time (3.5 months) following cheaper storage under force-ventilated ambient cooling.
Much smaller losses at 0°C showed that refrigerated storage offered more advantages than high temperature storage for marketing onion bulbs in the UK in June.
