摘要：

为了保护紫苏籽油中多不饱和脂肪酸的生物活性，扩大紫苏籽油的应用范围，以阿拉伯胶和β-环糊精(β-CD)为壁材，通过喷雾干燥法制备微胶囊，研究该微胶囊的理化指标。结果表明，紫苏籽油微胶囊含水量2.17%，堆积密度0.43 g/cm3，休止角36.27°，溶解度74.65%，具有较好的溶解性能；粒径大小合适，平均直径17.52 μm，不会产生吞咽感，包埋率86.52%。微胶囊紫苏籽油中不饱和脂肪酸相对含量70.85%，与未微胶囊化紫苏籽油无显著差异(P>0.05)，说明喷雾干燥法未破坏紫苏籽油的营养成分。微胶囊在92.85℃产生玻璃态转变，说明日常的温度处理不会破坏微胶囊的表面结构。随着热处理时间的增加，微胶囊过氧化物值(POV)和巴比妥酸值(TBA)上升速度显著低于紫苏籽油(P<0.05)，说明微胶囊贮藏稳定性更好。由此可知，该紫苏籽油微胶囊可以添加到热饮品中，尤其是婴幼儿配方乳粉，具有非常广阔的应用前景。

Abstract:

In order to protect the biological activity of polyunsaturated fatty acids of perilla seed oil and expand its application, we prepared perilla seed oil microcapsules by spray drying method with acacia and β-cyclodextrin as wall materials and then determined the physicochemical indexes of the microcapsules. The results showed that perilla seed oil microcapsules had good solubility of 74.65%, with water content of 2.17%, bulking density of 0.43 g/cm3, and the angle of repose of 36.27°. The average diameter was 17.52 μm, which could not cause swallowing sensation, and the embedding rate was 86.52%. The relative content of unsaturated fatty acids in microencapsulated perilla seed oil was 70.85%, which was not significantly different from non-microencapsulated perilla seed oil (P>0.05), indicating that spray drying method did not destroy the nutritional components of perilla seed oil. The glass transition temperature of the microcapsules was 92.85℃, showing that the surface structure of the microcapsules could not be destroyed by daily temperature treatment. With the increase of heat treatment time, the increase rate of peroxide value (POV) and barbituric acid value (TBA) of the microcapsules were significantly lower than that of perilla seed oil (P<0.05), indicating that the microcapsules had better storage stability. Thus, the perilla seed oil microcapsule can be added into hot drinks, especially infant formula milk powder, and has a very broad application prospect.
