Influence of Ventilation and Humidity During Storage on Weight and Quality Changes of White Yam Tubers (Dioscorea rotundata Poir)

Abstract

Maintaining at least 95% relative humidity in the ventilating air caused significantly less weight loss than ventilating with air at 85% relative humidity. In addition, significantly less shrivelling, and sprouting were found in tubers ventilated with air at 95% relative humidity. There was no difference between the two air humidities in the amount of rot found. Intermittent ventilation allowed significantly less weight loss than continuous ventilation. Also intermittent ventilation caused significantly less shrivelling and less sprouting than continuous ventilation.
