摘要

本研究利用油酸鈉、羧甲基纖維素鈉及幾丁聚醣作為被膜劑及使用N-（3-氯苯基）甲醯胺異丙酯（CIPC）抑芽劑處理臺農66號甘藷，結果發現使用抑芽劑CIPC可有效延緩甘藷的發芽時間至少20天，而油酸鈉可有效減緩甘藷重量之損失，而且使得甘藷在光澤、氣味及整體接受性之品評分數高於未處理之甘藷。在甘藷採收至發芽期間之化學成分變化方面，利用油酸鈉及／或CIPC處理之甘藷，其水分之散失可減緩；粗蛋白與粗脂肪含量均無顯著之變化；β-胡蘿蔔素含量在儲藏的末期（即發芽前）有微升的趨勢；澱粉和總糖含量則彼此有消長之現象。整體而言，被膜劑和抑芽劑的使用，可延緩臺農66號甘藷的發芽時間，但對於其主要組成分含量並不會造成顯著的變化。

Sodium oleate, sodium carboxymethyl cellulose, and chitosan were used as coating agents and isopropyl N-(3-chlorophenyl) carbamate (CIPC) was applied as a sprout-inhibitor for TN66 sweet potatoes. The application of CIPC delayed the sprouting of TN66 sweet potatoes for at least 20 days. Sodium oleate effectively prevented weight loss and improved luster, odor, and acceptability of TN66 sweet potatoes. The sweet potatoes, treated with sodium oleate and/or CIPC, had less moisture loss compared to the control group. There were no significant changes in crude fat and protein contents. The content of beta-carotene slightly increased by increasing the storage time. A vicissitude occurred between the starch and total sugar contents. Generally speaking, the coating agent and sprouting-inhibitor used in this study delayed the sprouting of TN66 sweet potatoes and caused no significant changes in the contents of major components of TN66 sweet potatoes.
