中文摘要:
      目的 探究不同温度下金玉兰菜采后贮藏品质和生理特性的变化,建立其货架期预测模型。方法 分别设置货架温度为1、4、10、20 ℃,对比分析不同贮藏温度下金玉兰菜的感官品质、呼吸速率、乙烯释放量、叶绿素含量、类胡萝卜素含量、总酚含量和芽球叶部色差值(L*a*b*)的变化情况;将质量损失率和叶部色差L*值作为特征指标,应用Arrhenius方程和化学动力学方程,建立金玉兰菜货架期的动力学模型。结果 与10 ℃和20 ℃贮藏条件相比,1 ℃和4 ℃低温贮藏可显著延缓金玉兰菜的品质劣变进程,降低叶绿素、类胡萝卜素、总酚等含量的下降速率(P<0.05),采用1 ℃低温贮藏能更好地抑制金玉兰菜呼吸强度和乙烯释放量的上升,并推迟呼吸峰值的出现,显著延长了金玉兰菜的货架期。结论 所得预测模型的平均相对误差均在±5%以内,可准确预测1~20 ℃内金玉兰菜的货架期,为金玉兰菜采后贮藏温度条件的选择和货架期监测提供了参考依据。
英文摘要:
      This paper aims to explore the storage quality and physiological characteristics of postharvest Cichorium intybus L. var. foliosum Hegi. under the different temperatures, and establish its shelf life prediction model. In this experiment, shelf temperatures of 1, 4, 10 and 20 ℃ were set to compare and analyze the changing conditions of the sensory quality, respiration rate, ethylene release, chlorophyll content, carotenoid content, total phenol content, and color difference value of Cichorium intybus L. var. foliosum Hegi.. The quality loss rate and leaf color difference L values were used as characteristic indexes, and the Arrhenius equation and chemical kinetic equation were applied to establish the kinetic model of the shelf life of Cichorium intybus L. var. foliosum Hegi.. The results showed that compared with the experimental groups at 10 and 20 ℃, low-temperature storage at 1 and 4 ℃ could significantly delay the quality deterioration of the Cichorium intybus L. var. foliosum Hegi., and decrease the rate of descent of chlorophyll, carotenoid, and total phenol (P<0.05). Low-temperature storage at 1 ℃ can better inhibit the increase of respiratory rate and ethylene release rate, delay the occurrence of the respiratory peak, and prolong the shelf life significantly. The average relative errors of the prediction models were all within ±5%, which could be used to accurately predict the shelf life of Cichorium intybus L. var. foliosum Hegi.. This experiment provides a reference for the selection of postharvest storage temperature conditions and shelf life monitoring of Cichorium intybus L. var. foliosum Hegi..
