气调冷藏集装箱对蔬菜贮藏的保鲜效果

Effect of Air-conditioned Refrigerated Container on Preservation of Vegetables

  • 摘要: 为探讨气调冷藏集装箱的保鲜效果,以常见蔬菜小白菜、油麦菜、芹菜、菠菜为试材,在1 ℃条件下,分别用气调冷藏集装箱与普通冷库贮藏,气调环境为5%±1% O2、95%±1% N2,相对湿度为90%±5%,乙烯脱除模块每天凌晨脱除0.5 h,臭氧杀菌模块每天灭菌一次,浓度2 g·min−1,时间是10 min,而普通冷库除冷藏外不再增加其他措施。通过测定贮藏期间蔬菜的失重率、可溶性固形物、可滴定酸、抗坏血酸、呼吸强度、丙二醛、叶绿素指标,评价设备保鲜性能。结果表明,与普通冷库相比,在45 d贮藏期内,气调冷藏集装箱明显能有效防止蔬菜水分的散失,维持较高的可溶性固形物、可滴定酸含量,在一定程度上抑制了果蔬的呼吸作用,降低抗坏血酸、叶绿素的消耗,减轻叶片细胞膜质过氧化的程度,能有效延缓蔬菜腐烂变质的时间,保持蔬菜较好的贮藏品质。因此,气调冷藏集装箱对大批量蔬菜的贮藏具有良好的应用前景。

     

    Abstract: In order to study the fresh-keeping effect of air-conditioned refrigerated container, both the air-conditioned refrigerated container and common cold storage were used to preserve fresh vegetables (pakchoi, leaf lettuce, celery and spinach) under 1 ℃. The controlled atmosphere was 5%±1% O2, 95%±1% N2, and the relative humidity was 90%±5%. The ethylene removal module runned for half an hour every morning, and the ozone sterilization module worked for 10 minutes once a day, with the concentration of 2 g·min−1. While, there were no other measures for common cold storage in addition to cold storage. The indicators of the weight loss rate, soluble solids content, titratable acid content, VC, respiration intensity, MDA and chlorophyll content were investigated to evaluate the preservation performance of the equipment. The results showed that during 45 d storage period, the air-conditioned refrigerated container performed better on effectively preventing vegetables weight loss, maintaining high soluble solids and titratable acid content, inhibiting the respiration intensity of vegetables, reducing the consumption of VC and chlorophyll, also relieving the degree of cell membrane peroxidation in leave. Furthermore, it can effectively retard the corruption of vegetable and maintain the fresh quality of vegetables. In conclusion, air-conditioned refrigerated container has a better application prospect for storage of large quantities of vegetables.
