摘要: 本文采用自己制备的高纯度丹皮酚磺酸钠对樱桃番茄果实进行保鲜作用的研究,并探讨其作用机制。结果表明:丹皮酚磺酸钠能有效降低贮果的失重率和霉变率,显著延缓了贮藏过程中贮果膜透性的增加,明显抑制了贮果中总有机酸、维生素C和可溶性蛋白质含量进行性减少的趋势,较大程度上维护贮果细胞中超氧物歧化酶(SOD)的活性。对贮果的保鲜效应与所应用丹皮酚磺酸钠的浓度成显著的正相关性,其保鲜作用的机制可能与丹皮酚磺化物有明确的抑制植物病原菌及有较强的自由基清除作用相关。

Abstract: The preservation effects of highly purified SPS on cherry tomatoes and their mechanism were investigated in this paper. Results showed that, during the storage period, SPS could effectively reduce the rates of its weight-lost and mildewing, delay the increase of the membrane permeability, inhibit the decrease of the contents of the total acidity, vitamin C and soluble protein, and resist the changes of the SOD activities. Results also indicated a close positive correlationship between the preservation effects of SPS and its concentration in treatment. Their preservation function might owing to their antioxidant and antimicrobial capabilities.
