香味微膠貴的外殼稱為壁材、是採用高分子化合物如明膠、阿拉伯樹膠等在水溶液中善膠費的成化而成,約占香味微膠囊組成的60%

這種香味微膠森的壁材不僅具有儲存微細狀態的香精或香料的性能,而且能在需要時釋放出香精或香料。

明膠作為壁材的主體,在加熱到35℃時,能成為無色透明的液體,其等電點pH值為4.7,當冷卻後明膠則會發生凝固,明膠對其他膠體有很強的保護作用。

與甲醛(或戊二
醇)發生硬化反應可生成堅硬的甲醛明膠聚合物每,拉伯樹膠的稀水溶液能形成物理吸附預,在配製吞味微膠囊中,形成內包覆層,由明護構成外包層。

芯材即為膠囊所包覆的香精或香料物質細粒,約占香味微膠囊的40%香味微膠囊的制10%的明膠水溶液和19的阿拉伯樹酸溶液各90g,混合後加入水20om,並加熱到保溫

在不斷攪拌(授拌速度為1500min)的過程中,逐漸慢慢加入香精或香料120ml,使之分離成20m左右的膠小滴,並均勻地分散在明膠混合液中。

109的醋酸水溶液或5%-10%的氫氧化鈉水溶液來調節合成液的pH值,使其保持在4.7。降溫至15℃左右時加入30%的甲醛(或戊二醇)水溶液510m

可使膠囊小滴硬
化成香味微膠囊,並用離心脫水裝置反復水洗制取香味微膠囊漿液。

可用香味微膠囊漿液與硝基纖維素混合製成水劑型香味油墨,或先把香味微膠囊漿液進行乾燥制取成固體粒香味微膠囊,並作為一種添加劑均勻地分散在印刷油墨中,

調配成香味當調墨量大而採用調墨機時,也應註意保護微膠囊。香味微膠囊分散到油墨中,不能軋碾,也不能使用高速葉輪攪拌,防止膠囊被碾破,使香味散失。
