采用连续滴加的乳液聚合工艺,以过硫酸钾-亚硫酸氢钠作为纯丙乳液氧化还原聚合的引发剂,以AES和K12作为高效乳化剂,制得了微胶囊粒径约6μm的水性纯丙香味乳液。研究了微胶裳的颗粒大小和壁厚对香味乳液放香特性的影响。实验表明:当m(BA):m(MMA):m(MAA)=33:17:1时,香味乳液的综合性能良好,香精在微胶囊纯丙乳液中的缓释时间可达9个月。
採用連續滴加的乳液聚閤工藝,以過硫痠鉀-亞硫痠氫鈉作為純丙乳液氧化還原聚閤的引髮劑,以AES和K12作為高效乳化劑,製得瞭微膠囊粒徑約6μm的水性純丙香味乳液。研究瞭微膠裳的顆粒大小和壁厚對香味乳液放香特性的影響。實驗錶明:噹m(BA):m(MMA):m(MAA)=33:17:1時,香味乳液的綜閤性能良好,香精在微膠囊純丙乳液中的緩釋時間可達9箇月。

A sort of waterborne pure acrylic flavor emulsion with 6 microns in diameter was synthesized using methyl methacrylate ( MMA ), butyl acrylate ( BA )and methacrylic acid ( MAA )as mixtured monomers, the lauryl sodium sulfate ( K12 ) and the sodium fatty alcohol ether sulfate ( AES ) as a high efficiency emulsifier, and potassium persulfate and sodium bisulfite as initiator. The influences of microcapsule partical size and wall thick in coat on fragrance-released characteristic of flavor emulsion were discussed in detail. It was indicated that when m/BA : m(MAA) : m(MAA) is equal to 33 : 17 : 1, the fragrance-released time of flavor emulsion can reach as far as 9 months, and the comprehensive performance of the emulsion is satisfactory.
