鲜切茄子冷藏生理及品质的研究

Study on cold storage physiology and quality of the fresh-cut eggplant

  • 摘要: 以新鲜的茄子为实验材料,对不同贮藏温度下的鲜切茄子的品质变化和保鲜效果进行了研究。新鲜的茄子经过切分处理后,用聚乙烯保鲜膜(厚度0.02mm)包装,分别贮藏于相对湿度(RH)85%~90%的(5±2)、(10±2)、(15±2)、(22±2)℃(室温)恒温恒湿箱中,每天测定鲜切茄子的褐变度、抗坏血酸、可滴定酸、多酚氧化酶(PPO)和过氧化物酶(POD)的活性等指标。结果表明:(5±2)℃和(10±2)℃与贮藏于(15±2)℃和(22±2)℃(室温)的贮藏条件相比,可以显著(p<0.05)抑制鲜切茄子组织褐变以及PPO和POD的活性,降低质量损失率,延缓组织中抗坏血酸、可滴定酸、可溶性固形物的下降。 

     

    Abstract: The experiment selected fresh eggplant as experimental material, the effect of different storage temperatures on quality and preservation of fresh-cut eggplant was investigated. Fresh eggplants were packaged with 0.02mm polyethylene packaging film after cutting processing to storage in cooling incubators at 85% 90% relative humidity (RH) and different temperatures (5 ±2) , (10 ±2) , (15 ±2) , (22 ±2) ℃ (room temperature) , respectively. Browning degree (BD) , the contents of ascorbic acid and titratable acid, activities of polyphenol oxidase (PPO) and peroxidase (POD) were measured every day. Results indicated that (5±2) ℃ and (10±2) ℃ showed significantly (p<0.05) inhibition of fresh-cut eggplant tissue browning, the activity of PPO and POD and weight loss rate during storage, compared with (15±2) ℃ and (22±2) ℃ (room temperature) , delayed the descend of titratable acid content and ascorbic acid content.
