The Effects of Storage Amount and Ventilator Size on the Quality of Ginger During Cellar Storage

저장량과 환기구크기가 움저장 생강의 저장성에 미치는 영향

An experiment was conducted to develop the simple methods of ginger storage which decrease the weight reduction and maintain good quality of ginger during the cellar storage. The stored boxes with volume of 0.03㎥ and ventilator diameter of 3, 4, 5cm was hurried under the ground(60, 80, 100cm) in the green house. During the cellar storage at the 100cm depth the average temperature and relative humidity in the stored box were remained in 11.7~16.3$^{\circ}C$ and 73%, respect. The higher storage amount and smaller size of ventilator size increased the CO2 concentration in the stored box, and the concentration in the stored box with 50% storage quantity rate and 3cm ventilator diameter size was more than 10% for about 2 months from early Feburary. The decay rate of ginger during the cellar storage increased with higher amount of storage quantity and smaller size of ventilator. The CO2 concentration was low and remained relatively constant with the deeper location of stored box under the ground, and the decay rate was lower in the deeper stored box. Germination rate increased with the deeper location of stored box, and with the lower storage quantity and larger ventilator size. The germination rate was low in the higher decay rate box. Weight loss, total sugar and moisture contents of ginger were decreased, while crude fiber and ash were increased during the storage.
