以2-氰基丙烯酸正丁酯(BCA)为壁材,檀香香精为芯材,通过乳液聚合法制备纳米香精胶囊。通过一系列单因素和正交试验分析考察香精用量、壁材用量,乳化剂用量及pH等因素对纳米檀香香精胶囊粒径大小的影响,得出檀香纳米胶囊的最佳工艺条件为:2-氰基丙烯酸正丁酯用量0.8%,香精添加量0.2%,乳化剂用量1%,pH 3.0。所制备的纳米檀香香精胶囊的平均粒径为112.31 nm。 Using n-butyl 2-cyanoacrylate (BCA) as the wall material and sandalwood flavor as the core material, nanometer essence capsules were prepared by emulsion polymerization. Through a series of single factor and orthogonal test, the effects of the amount of fragrance, the amount of wall material, the amount of emulsifier and pH on the particle size of nano-sandalwood capsule were investigated. The optimum conditions of sandalwood capsule were as follows: The amount of n-butyl 2-cyanoacrylate was 0.8%, the amount of flavor was 0.2%, the amount of emulsifier was 1%, pH 3.0. The prepared nano sandalwood capsule has an average particle size of 112.31 nm.
