低温贮藏苹果失水影响因素

Factors affecting moisture loss of apple stored in cold conditions

影响果蔬品质的最重要的原因之一是果蔬失水,在低温储藏中,尽量减少果蔬水分的流失,使果蔬长时间保鲜。以苹果作为研究对象,开展了正交实验研究,分析了温度、湿度、风速对果蔬失水的影响。实验结果表明;温度、湿度、风速对苹果的失水存在交互作用,交互的作用大于单个因素的影响;湿度和风速一起作用对失水的影响最大;失水率和温度梯度成正比。

One of the most important reasons affect fruit and vegetable quality is dehydration, We should minimize water loss of fruits and vegetables when low-temperature storage. Doing orthogonal experimental with apple and analysis the affect that the temperature, humidity, air velocity on the fruit and vegetable dehydration. Experimental results show that, Temperature, humidity and air velocity have interaction impact on the dehydration of apple, its effect is greater than every single factor impact on the dehydration of apple, humidity and air velocity have the greatest impact on the dehydration of apple. Thewater loss rate is proportional to the temperature gradient.
