摘　　要：以淀粉和β-环糊精为原料,采用反相胶乳法制备淀粉-β-环糊精复合微球,并采用单因素法对比淀粉微球和淀粉-β-环糊精复合微球对茉莉花香精二氢芳樟醇的缓释效果.研究结果表明,淀粉-β-环糊精复合微球吸附率明显大于淀粉微球,且淀粉-β-环糊精复合微球吸附香精分子的吸附率随微球投加质量的增加而增大,当微球投加质量为0.3 g,吸附时间为2 h时,最佳吸附率可达到70%,且二氢芳樟醇浓度越大,吸附量基本不变,吸附率降低.With soluble starch andβ-cyclodextrin(β-CD)as main raw materials,a composite microsphere based onβ-CD-starch has been synthesized by reversed phase emulsion polymerization,and the optimal process conditions of dihydrolinalool essence adsorbed by composite microsphere been preferred by single-factor experiment method.The research results show that,the adsorption rate ofβ-CD-starch is significantly higher than that of starch,and the rate increased with the increase of microsphere content,and the adsorption rate of dihydrolinalool by composite microsphere could reach70%,and it has the better sustained release ability when adsorption time was 2 h,composite microsphere was 0.3 g.The higher the concentration,the lower the adsorption rate with the same adsorption amount.
