    新鲜果蔬气调包装保鲜原理 新鲜果蔬用透气性塑料薄膜包装密封后,果蔬的呼吸活动消耗包装内空气中的O2并产生差不多等量的CO2,逐渐构成包装内与大气环境之间的气体浓度差。空气中的O2通过塑料薄膜渗透入包装补充消耗的O2,包装内的CO2则渗透出塑料薄膜扩散到空气中,开始时,包装薄膜内外的气体浓度差小,渗入包装内的O2不足以抵消消耗的,渗出的CO2小于产生的CO2。随着贮藏过程中包装内外气体浓度差增加,气体渗透的速度加快。当包装内O2消耗速度等于O2渗入速度,而CO2产生的速度等于渗出的速度时,包装内可能达到一个低02和低C02气调平衡浓度。如果包装内的气体平衡浓度使果蔬仅产生微弱的需氧呼吸而没有厌
