摘　　要：研究蔗糖基聚合物涂膜对成熟金橘的采后保鲜效果,测定贮存过程中金橘的出汁率、总糖、VC及过氧化氢酶等几个生理生化指标变化情况。结果表明:室温贮存20d内,蔗糖基聚合物处理能够有效减缓果实中水分的散失,促进金橘总糖的积累,减缓果实中VC的降解,提高果实中过氧化氢酶活性。为蔗糖基聚合物的推广应用提供试验依据。Experiments for storage of Fortunella margarita fruit using sucrose-based polymers was carried out. Juice yield, total content of sugars, vitamin C content and catalase activity of Fortunella margarita fruit stored at room temperature were studied. The results showed that application of sucrose-based polymers obviously slowed down the decline in water loss and vitamin C content, increased total content of sugars and catalase activity in a storage period of 20 days. The study provided the experimental data for the practical application of the sucrose-based polymers.
