摘要
以"西州密25号"哈密瓜为试材,采用差压预冷的方法,研究了不同预冷风速与温度对贮藏期哈密瓜果实乙烯释放量和呼吸速率的影响,确定差压预冷合适的风速和温度,为哈密瓜的差压贮藏提供理论依据。结果表明:在0~2℃预冷温度条件下,预冷风速以2.0m·s^(-1)抑制乙烯的释放量和减少果实的呼吸速率效果较为明显。而在3.0m·s^(-1)预冷风速条件下,预冷温度以2~4、4~6℃时抑制乙烯的释放量和减少果实的呼吸速率效果较明显,故确定哈密瓜差压预冷风速和温度分别为2.0m·s^(-1)和2~6℃。
Taking ＇Xizhoumi No. 25＇ Hang melon as test material,using the method of forced-air precooling,the effect of different preeooling temperatures and different precooling wind speeds on ethylene release quantity and respiratory rate were determined to search suitable wind speed and temperature of forced-air precooling in ＇ Xizhoumi No. 25＇ Hang melon for providing the theoretical basis of forced-air precooling of Hang melon. The results showed that when precooling temperature was 0-2 ℃ ,2. 0 m.s^-1 of wind speed could reduce obviously released quantity of ethylene and respiratory rate. When precooling wind speed was 3. 0 m .s^-1 ,2--4 ℃ and 4-6 ℃ of temperature could reduce obviously release quantity of ethylene and respiratory rate. Precooling wind speed of 2. 0 m .s^-1 and precooling temperature of 2--6 ℃ were suitable.
