MeJA与CTS涂膜处理对李采后果实品质及抗氧化活性的影响
Effects of MeJA and CTS Coating Treatment on the Quality and Antioxidant Activity of Postharvest Plum Fruits
摘要
Abstract
[Objective]To investigate the effects of methyl jasmonate(MeJA)and chitosan(CTS)on the quality and antioxidant activity of postharvest Jinmi plums stored at room temperature(25℃±1℃).[Method]With distilled water treatment as a control(CK),Jinmi plums were soaked in solutions of 100 µmol/L MeJA,0.5%CTS and 100 µmol/L MeJA+0.5%CTS solutions for 10 min,and the changes of storage quality and antioxidant capacity were measured within 10 days.[Result]Compared to CK,0.5%CTS,100 µmol/L MeJA and 100 µmol/L MeJA+0.5%CTS composite treatments reduced the rot-ting and weight loss rates of the plums,while improved the hardness and antioxidant capacity of fruit.Among them,the combined treatment of 100 µmol/L MeJA+0.5%CTS was the most effective,reducing the rotting and weight loss rates by 12.78%and 1.07%,respectively;and increasing hardness and antioxidant capacity by 63.64%and 33.93%,respectively.[Conclusion]Both 0.5%CTS and 100 µmol/L MeJA treatments could prolong the storage time of Jinmi plums and delay the deterioration of fruit quality,with the combined treatment of 100 µmol/L MeJA+0.5%CTS had the best preservation effect.关键词
