- 摘要:
- 以“新余”蜜橘为试材，设2.0%壳聚糖(T1)以及2.0%壳聚糖+70 mg/mL三颗针提取液(T2)涂膜处理，以清水为对照(CK)，置于温度(5±1)℃，相对湿度(RH) 80%～90%的条件下贮藏，测定“新余”蜜橘生理生化指标，观察其保鲜效果，研究壳聚糖及三颗针醇提液复合膜对“新余”蜜橘贮藏保鲜效果的影响。结果表明：与清水对照组相比，2.0%壳聚糖和2.0%壳聚糖+70 mg/mL三颗针提取液涂膜均能有效地降低果实的腐烂率和失重率，减少营养成分的消耗，并能抑制果实丙二醛(MDA)和过氧化氢(H2O2)的积累，维持贮藏后期较高的超氧化物歧化酶(SOD)、苯丙氨酸解氨酶(PAL)、多酚氧化酶(PPO)、过氧化物酶(POD)等酶活性，从而增强果实的抗病性、减少病原菌的侵染，但2.0%壳聚糖+70 mg/mL三颗针提取液复合涂膜(T2)对“新余”蜜橘的效果优于2.0%壳聚糖处理，能更好地维持“新余”蜜橘较好的品质，具有较优的贮藏保鲜效果。
- Abstract:
- The preservation effect of chitosan and barberry root extracts combined coating on ‘Xinyu’ tangerine was explored，set 2.0% chitosan(T1)，2.0% chitosan+70 mg/mL barberry root extracts(T2) and clean water as the control group(CK)，storaged at (5±1)℃ and RH 80%-90%，and then determined physiological and biochemical indexes，observed their effects.The results showed that，compared with the control group，2.0% chitosan and 2.0% chitosan+70 mg/mL barberry root extracts coating on ‘Xinyu’ tangerine could decrease decay rate and weight loss effectively，reduce the consumption of nutrients，and could inhibit MDA and H2O2 accumulate significantly，keep higher activities of SOD，PAL，PPO and POD at the late storage period，enhance the disease resistance of the fruit and then reduce the infection of fungus，according to the results，the effect of 2.0% chitosan+70 mg/mL barberry root extracts coating was superior to 2.0% chitosan.On the basis of test parameters，it suggested that 2.0% chitosan+70 mg/mL barberry root extracts coating(T2) could keep a better quality of ‘Xinyu’ tangerine，present excellent storage preservation effects.
