【摘要】：以槲皮素為芯材,殼聚糖、海藻酸鈉為壁材,采用復(fù)凝聚法制備槲皮素微膠囊。以包埋率和載藥量為綜合評(píng)價(jià)指標(biāo),通過單因素試驗(yàn)和響應(yīng)面試驗(yàn)分析各因素,并對(duì)槲皮素微膠囊的理化性質(zhì)進(jìn)行研究。結(jié)果表明:壁材比(殼聚糖-海藻酸鈉質(zhì)量比)1∶3.34(g/g)、芯壁比4.34∶1(g/g)、京尼平用量18.44 g/100 g殼聚糖、固化溫度41.56℃時(shí),包埋率為69.53%。制備的槲皮素微膠囊水分含量為3.26%,休止角為40.39°,溶解度為256.44μg/m L,粒徑大小較為均勻,平均粒徑為1 362 nm,具有較好的溶解性和穩(wěn)定性。
[Abstract]:Using quercetin as core material, chitosan and sodium alginate as wall materials, quercetin microcapsules were prepared by complex coagulation method. The physicochemical properties of quercetin microcapsules were studied. The results showed that the ratio of wall to material (mass ratio of chitosan to sodium alginate was 1: 3.34 g / g / g), core / wall ratio was 4.34: 1 g / g / g, amount of genipine was 18.44 g / 100 g chitosan, curing temperature was 41.56 鈩，
