摘要
[目的]研究蔗糖基聚合物对茂谷柑的保鲜效果。[方法]用0.5%、0.7%、1.0%浓度的蔗糖基聚合物对茂谷柑进行采后处理,研究其对茂谷柑的丙二醛含量(MDA)和超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性的影响。[结果]采后进行蔗糖基聚合物处理茂谷柑,可以提高SOD、CAT活性,降低MDA含量和POD活性。[结论]蔗糖基聚合物在延缓果实组织的衰老,减少营养物质的消耗,延长贮藏寿命方面有较好的效果。
[ Objective ] The purpose was to study the fresh-keeping effects of sucrose-based polymers on Murcott. [ Method ] The post-harvest Murcott was treated by sucrose-based polymers with concentration of 0.5% , 0. 7% and 1%. The content of malondialdehyde （MDA） and the activities of Superoxide dismutase （ SOD）, Peroxidase （POD） and Catalase （CAT） in the Murcott fruit were investigated. [ Result ] Sucrosebased polymers could enhanced the SOD, CAT activity, decreased the MDA content and POD activity. [ Conclusion] Sucrose-based polymers could slow obviously decay of fruit, retain the consumption of nutrient content, and prolong the storage life.
