摘要

本研究利用液中硬化法製備微膠囊，以海藻酸鈉作為微膠囊之殼材，檸檬精油為芯材，使用不同氯化物及硫酸金屬交聯劑探討其成形性及對平均粒徑之影響，根據結果得知使用不同交聯劑對微膠囊外觀成形及粒徑影響不大，使用氯化鈣及硫酸鋅可得到最小粒徑，分別為3.51±0.08μm和3.13±0.20μm，經釋放曲線圖，可得知使用氯化鈣及氯化鎂交聯劑具有較佳的緩釋效果。

In this study, we use sodium alginate as the shell, lemon oil as the core to prepare the calcium alginate microcapsules encapsulated lemon oil by orifice method. Use various chloride and sulfate metal crosslinking to explore the influence of formability and average particle size, and explore the difference in release and the encapsulation efficiency. According to the results, using various cross-linking to appearance formability and average particle size has a little influence of microcapsule, the minimum particle size was 3.51±0.08μm and 3.13±0.20μm at calcium chloride and zinc sulfate. By release curve diagram, using calcium chloride and magnesium chloride crosslinking have better sustained-release effect.
