Abstract

Microcapsules including red beet extract rich in betanin was produced by ionic gelation. Sodium alginate was used as wall material. Impacts of coating amount and active material were assessed with respect to encapsulation eﬃciency (EE) of the capsules in terms of total phenolic content (TPC). Encapsulation of the red beet extract in alginate microbeads was satisfying with >80% under the best conditions of ionic gelation (15% calcium chloride concentration and 2% sodium alginate for 15 min of hardening time). The interaction between the active material and the alginate beads were also investigated by diﬀuse reﬂectance fourier transform (DRIFT) spectroscopy. Accelerated oxidation test was employed to measure the stability of the microcapsules against oxidation by means of Rancimat method. Stability of the produced microbeads were evaluated in terms of kinetic and thermodynamic analyzes. After the induction times were determined under diﬀerent temperature conditions (110, 120, 130 and

海藻酸盐微胶囊中甜菜素的捕获:加速条件下的稳定性研究

采用离子凝胶法制备了富含甜菜素的红甜菜提取物微胶囊。采用海藻酸钠作为壁材。以总酚含量(TPC)评价包衣量和活性物质对胶囊包封效率(EE)的影响。在氯化钙浓度为15%、海藻酸钠浓度为2%、硬化时间为15 min的最佳离子胶凝条件下，红甜菜提取物在海藻酸微球中的包封率为> ~ 80%。利用漫反射傅立叶变换(DRIFT)光谱研究了活性物质与藻酸盐珠的相互作用。采用加速氧化法测定微胶囊的抗氧化稳定性。通过动力学和热力学分析评价了所制微球的稳定性。在不同温度条件下(110、120、130、30℃)测定诱导次数
