【摘要】：以β-大馬酮為囊芯材料,明膠和羧甲基纖維素鈉(CMC)為壁材,通過復(fù)凝聚法制備了β-大馬酮微膠囊。以單因素試驗(yàn)為基礎(chǔ),通過正交試驗(yàn)優(yōu)化了β-大馬酮微膠囊制備的工藝條件。確定較佳工藝條件為:m(明膠):m(CMC)=9:1,m(芯材):m(壁材)=1:1,乳化速度8 500 r/min,固化劑用量0.25%,溶液pH=4.5~4.6,反應(yīng)溫度40℃。在此條件下,微膠囊的包埋率達(dá)到了97.83%±2.16%,其粒徑約為30μm,形貌圓整規(guī)則。
[Abstract]:尾 -Damarone microcapsules were prepared by complex coacervation with gelatin and sodium carboxymethyl cellulose (CMC) as wall materials. Based on the single factor test, the preparation conditions of 尾-Damarone microcapsules were optimized by orthogonal test. The optimum technological conditions are as follows: 1: M (CMC) 9: 1 m (core): 1: 1, emulsifying rate is 8 500 r / min, the amount of curing agent is 0.25, the reaction temperature of solution is 40 鈩，
