- 摘要:
- 以PE/OPP/PE复合膜、PE膜及电晕处理PE膜为试材，采用与空气相同（21% O2+09% CO2）的初始气体比例被动气调包装件，研究不同透气、透湿性能的薄膜对草莓气调保鲜效果的影响。结果表明：在室温（15±2）℃、相对湿度33%～35%的条件下，在草莓6 d贮存期内，PE/OPP/PE复合膜保持了草莓较高的感官评价和硬度，电晕处理PE膜更有利于延缓草莓可溶性固形物含量的下降及pH的升高。故PE/OPP/PE复合膜和电晕处理PE膜对草莓的保鲜效果优于PE膜。
- Abstract:
- PE/OPP/PE composite film，PE film and corona processing PE film were used as test materials.Passive air conditioning package which had an initial gas ratio of 21% O2+09% CO2 was adopted.The effects of different air permeability，moisture permeability of the film on preservation effect of strawberry modified atmosphere were studied.The results showed that under the condition of room temperature（15±2）℃，relative humidity 33%-35%，PE/OPP/PE composite membrane maintained high sensory evaluation and hardness of strawberry，corona treatment of PE film was more conducive to delay the decline of soluble solids and the increase of pH.The effect of PE/OPP/PE composite film and corona treatment on the preservation of strawberry was better than that of PE film during the 6 days of storage.
