    摘要:

    根据壁材特性及凝胶工艺,以明胶和海藻酸钠为壁材,5%氯化钙溶液为固化剂,采用复合凝聚法制备天然VE微胶囊。研究两种壁材比例对天然VE微胶囊的微观形貌、粒径分布及其包埋效果的影响。结果表明,当明胶与海藻酸钠质量比为31时,制得的微胶囊形状规则,粒径适中且分布在30~60 μm,平均粒径35.17 μm,产率和效率以及固态时的有效载量均达到最高。

    Abstract:

    Nature VE Microcapsules was produced by using Composite gel method. This method of producing Nature VE Microcapsules was based on the properties of wall material and Complex coacervation process. Gelatin and Alginate were used as wall materials, and 5% of calcium chloride was chose as curing agent. The influence of two different proportion of wall material to Nature VE Microcapsules Morphology and the effects of particle size distribution and embedding were also researched. The results showed that the production rate and efficiency as well as the solid effective loads were highest when the ratio of gelatin wall at materials: alginate = 31, combining with the shape of produced microencapsulation a rule spherical and particle size distribute appropriate ranging from 30 μm to 60 μm, and the average particle size at 35.17 μm.
