The goal of this work was to select the best combination of encapsulants for the microencapsulation of oregano essential oil by spray dryer with the addition of Arabic gum (AG), modified starch (MS) and maltodextrin (MA). The simplex-centroid method was used to obtain an optimal objective function with three variables. Analytical methods for carvacrol quantification, water activity, moisture content, wettability, solubility, encapsulation efficiency (ME) and oil retention (RT) were used to evaluate the best combination of encapsulants. The use of AG as a single wall material increased ME up to 93%. Carvacrol is the major phenolic compound existent in the oregano essential oil. Carvacrol exhibits a maximum concentration of 57.8% in the microparticle with the use of 62.5% AG and 37.5% MA. A greater RT (77.39%) was obtained when 74.5% AG; MS 12.7% and 12.7% MA were applied, and ME (93%) was improved with 100% of gum.

这项工作的目的是通过喷雾干燥器选择最佳的密封剂组合,以通过添加阿拉伯胶 (AG),改性淀粉 (MS) 和麦芽糊精 (MA) 来微胶囊化牛至精油。使用单纯形-质心法获得具有三个变量的最佳目标函数。使用香芹酚定量,水活度,水分含量,润湿性,溶解度,包封效率 (ME) 和保油率 (RT) 的分析方法来评估包封剂的最佳组合。AG作为单一墙体材料的使用增加了我的93%。香芹酚是牛至精油中存在的主要酚类化合物。使用62.5% AG和37.5% MA,香芹酚在微粒中表现出最大浓度的57.8%。当74.5% AG时获得更大的RT (77.39%); 应用MS 12.7% 和12.7% MA,并且100% gum改善ME (93%)。
