摘要:

初步研究了气调保藏技术对天津地区南美白对虾的保鲜效果的影响。以感观检验、 多酚氧化酶活性(PPO)、挥发性盐基氮(TVB-N)及微生物为指标,研究不同配比的O2、CO2、N2 对对虾的保鲜效果。结果表明,气调保藏可以明显延长对虾的保鲜期,并且用10% 山梨醇保鲜剂处理后,75% CO2、20% N2、5% O2 的气调方式对虾的保鲜效果较好。

关键词: 气调保藏, PPO, T-VBN, 微生物指标

Abstract:

Preliminary study of the fresh-keeping effect of modified atmosphere packaging on South America white prawns was conducted. Sensory evaluation and biochemical and biochemical analysis were performed on the prawns preserved in a modified atmosphere box with different proportions of mixed O2, CO2 and N2. The shelf life of fresh South America white prawns was extended by modified atmosphere packaging and better fresh-keeping effects were observed when pretreatment of the fresh prawns with 10% sorbitol followed by modified atmosphere preservation with the composition of 75% CO2 + 20% N2 + 5% O2.

Key words: modified atmosphere preservation, polyphenol oxidase, total volatile basic nitrogen (TVB-N), microbial index
