The changes were investigated of TVR-NUTBA and pH in fresh fish which was packaged with packaging material having lower O2 permeability (material A) and higher 0;permeability (material B) under vacuum-packaging or custom package during storage at 20?. The results showed that the growth value of TVB-N and TBA in packaged fresh fish increased with increasing of storage time (t), and the growth rate of TVB-N was less in forepart than later-stage with less influence from the illumination. Meanwhile, growth rate of TBA was sharper in forepart than later-stage with larger influence from illumination, that means the illumination may hasten the growth of TBA, and the changes of pH were less in fresh fish shade-packaged shade than illumination.%以高阻隔材料A和低阻隔材料B两种包装材料,采用真空包装和普通包装两种包装方式包装鲜鱼肉,贮藏在20℃条件下,研究光照对包装鲜鱼肉挥发性盐基氯(TVB-N)、TBA以及pH的影响.结果表明:包装鲜鱼肉的TVB-N值、TBA值均随着贮藏时间的延长而增加,TVB-N值在贮藏前期变化速度比后期小,光照对其影响也较小,而TBA值的变化却前期快后期慢,光照影响较大,即光可以提高TBA值增加速度,光照条件下贮存的包装鲜鱼肉pH增加量均稍微高于避光贮存.
