2、定性變化不大。研究發(fā)現(xiàn)低粘度SSOS微膠囊包埋檸檬油的百分率在57．4％至87．6％(w／w)之間，并取決于SSOS的葡萄糖值。在壁材與芯材的質(zhì)量比大于3比2，葡萄糖值為12．8時，微膠囊包埋的產(chǎn)率和效率達到最高值。微膠囊在40℃下放置貯存3周后，其微膠囊化效率僅降低3％。通過掃描電鏡觀察，發(fā)現(xiàn)微膠囊為球形的未粘。連的顆粒，有些顆粒的表面并不平整。研究結(jié)果表明一定葡萄糖值的低粘度SSOS作為微膠囊壁材具有很好的包埋效果。關(guān)鍵詞：淀粉酯；低粘度辛烯基琥珀酸淀粉鈉(ssos)；壁材；包埋；檸檬油中圖分類號：R93；TS236文獻標識碼：AL
