蝶豆花因富含黃酮類化合物，酚類化合物以及大量花青素，可激發抗氧化活性，有助於減少因自由基引起的氧化作用。蝶豆花茶有助於抗發炎、止痛和改善疲勞。為增強與延續產品的有效性。本研究使用幾丁聚醣為壁材製備蝶豆花萃取物微膠囊，探討使用不同壁材濃度與芯材添加量對於蝶豆花萃取物微膠囊之包覆率與粒徑的影響，以及幾丁聚醣與交聯劑之間的比例來觀察對於蝶豆花微膠囊之之包覆率與粒徑。
實驗結果顯示：幾丁聚醣成功包覆蝶豆花萃取液微膠囊，當蝶豆花萃取液添加量為 55g 時，包覆率高達 89.60%，為實驗最佳結果。在顯微鏡的觀察下，微膠囊成球狀，並且具有深色外圍。幾丁聚醣包覆後之顏色亦能隨著不同酸鹼值來改變，本實驗由 pH6 調至 pH12 在再到 pH4，顏色上從藍色轉為深綠色再回到藍色，因此可利用調節酸鹼值來改變色澤。當添加三聚磷酸鈉作為交聯劑後，微膠囊的平均粒徑明顯減少，在未添加交聯劑的微膠囊粒徑大小約 1.5 μm，添加了交聯劑後小於 1.0 μm，證實幾丁聚醣確實可與三聚磷酸鈉作交聯，形成膠體微粒，變為較小粒子。
最後本實驗將蝶豆花萃取液微膠囊放入手工皂，發現包覆後的微膠囊在皂中具有不同的顏色，因此證明包覆蝶豆花微膠囊具有留色效果。

Clitoria ternatea is rich in flavonoids, phenolic compounds and a large number of anthocyanins, which can stimulate antioxidant activity and help reduce the oxidation caused by free radicals. Clitoria ternatea tea helps fight inflammation, relieve pain and improve fatigue. To enhance and extend the effectiveness of the product.In this study, chitosan was used as the wall material to prepare the Clitoria ternatea extract microcapsules, and the effects of different wall material concentration and core material addition on the coating rate and particle size of the Clitoria ternatea extract microcapsules were investigated. The ratio between the chitosan and the crosslinking agent was used to observe the coverage and particle size of the butterfly bean microcapsules.
The results showed that：the Clitoria Ternatea Microcapsules were prepared successfully. When Clitoria Ternatea extract was added to 55g, the encapsulation efficiency was 89.60% in the microscopic observation that microcapsules showing spherical and having a dark periphery. The dark periphery was the Clitoria Ternatea natural pigment. After chitosan Clitoria Ternatea extract, the color can be changed with different pH value. In this study, the pH was adjusted from pH 6 to pH 12 then pH 4, in color will from blue turn green and then blue. Therefore it can be used to adjust pH to adjust pH to change color. And when tripolyphosphate added as a curing agent, that significantly reduced the average particle diameter of the microcapsules. No curing agent microcapsule particle size of about 1.5 μm, but after adding the curing agent is less then 1.0 μm. It confirmed that chitsan does with sodium tripolyphosphate as cross-linked to form colloidal particles. It becomes smaller paeticles.
Finally, in this experiment, the Clitoria Ternatea extract microcapsules were put into the handmade soap, and it was found that the coated microcapsules had different colors in the soap, thus demonstrating that the coated Clitoria Ternatea microcapsules have a color retention effect.
