摘要
探讨了常温(18-24℃)和冷藏温度(12℃)条件下绿熟番茄在贮藏过程中与呼吸代谢相关的呼吸速率、呼吸商、呼吸底物中可溶性固形物含量以及有机酸含量的变化。通过对上述指标进行实验分析,结果表明:在冷藏条件下番茄呼吸速率水平比在常温条件下低,呼吸高峰的出现比在常温条件下晚5 d左右;经冷藏的番茄果实可溶性固形物含量比常温贮藏的高;番茄有机酸含量随贮藏时间的延长而呈下降趋势,冷藏番茄中有机酸的分解速度比常温贮藏的缓慢;呼吸商总体表现为下降趋势,不同的贮温其变化趋势与呼吸速率接近。说明了低温贮藏可有效降低番茄呼吸速率和呼吸底物的消耗,保持其良好的品质,提高其商品价值。
This paper studies changes of respiration rate,respiration quotient,organic acid,soluble solids of tomato related with respiration and metabolism at room temperature(18-24℃)and cold temprature(12℃).The results showed,respiration rate in tomato at cold temperature was lower than that at room temperature,the arrival of respiration peak is about 5 days later,the content of soluble solids at cold temperature was higher than that at room temperature.The organic acid in tomato was reduced with time extension.The decomposition of organic acid in tomato at low temperature was more slowly than that at room temperature.The respiration quotient was generally reduced.The change trend of storage temperalure was close to the respiration rate.The result showed that the storage at cold temperature could effcetively reduce the respiration rate of tomato to keep its good quality.
