摘要: 以交联木薯淀粉为主要原料,对蜜橘进行浸泡涂膜,以不涂膜组作为对照组,常温保藏36d,测定蜜橘的质量损失率、腐烂率、可溶性糖含量、呼吸强度和VC含量的变化。结果表明:交联木薯淀粉可有效延长蜜橘保藏期限,尤其是高交联木薯淀粉(沉降值3.4)对蜜橘的保鲜效果最佳,质量损失率、腐烂率、可溶性糖消耗量、呼吸强度和VC损失量均明显低于对照组。交联木薯淀粉保鲜膜对蜜橘保鲜效果良好。

Abstract: Cross-linked cassava starch was used as the major material to coat mandarin oranges. Coated mandarin oranges during the storage for 36 days at room temperature were subjected to the determination of changes in weight loss rate, decay rate, soluble sugar content, respiration intensity and vitamin C content. The results indicated that cross-linked cassava starch, especially highly cross-linked starch, could efficiently prolong the storage life of oranges. Compared with the control group, weight loss rate, decay rate, soluble sugar consumption amount, respiration intensity and vitamin C loss rate of the film-coated oranges were lower.  

Key words: mandarin orange, cross-linked starch, cassava starch, film-coating preservation
