日本最近研究出新的“冷温高湿储藏法”把冷库的温度调到0－1℃；湿度调到95％，并注入负离子和臭氧的混合气体。此法的好处在于，有些水果不能承受低温，但高温度可解决这一难题。低浓度臭氧不能杀菌，但加上负离子后杀菌能力明显提高而对水果不会造成不良影响。这种新保鲜法 Japan recently developed a new “cold and humid storage method,” the cold storage temperature is adjusted to 0-1 ℃; Humidity adjusted to 95%, and injected into a mixture of negative ions and ozone gas. The advantage of this method is that some fruits can not tolerate low temperatures, but high temperatures can solve this problem. Low concentrations of ozone can not be sterilized, but after the addition of negative ions significantly increased bactericidal effect on fruits will not cause adverse effects.
