The study describes the microencapsulation of Pterodon emarginatus fruit essential oil (OE) by spray drying using Brazilian Cerrado cashew polysaccharide (PEJU, Anacardium othonianum Rizz.) and maltodextrin (M) as wall materials. The microcapsules presented particles with irregular and rough surfaces confirmed by X-ray diffraction, with 57% in dry diameters ranging from 0 to 1 μm. Thermogravimetry showed a thermostable encapsulating material (peaks at 301 °C and 429 °C), with no loss of the encapsulated core. Zeta potential (ζ = − 0.18 mV) demonstrated the material’s amphiphilic power. The ratio of 1:3:3.6 of OE:cashew PEJU:M (w/w/w) showed the best encapsulation effect (75% yield and 6.25% of the OE retained) in the same proportion of β-caryophyllene retained. The Brazilian Cerrado cashew PEJU is a promising source for use as wall material in microcapsules, especially in protecting the OE of P. emarginatus fruits, as replacement for other gums, such as gum Arabic.

这项研究描述了使用巴西Cerrado腰果多糖（PEJU，拟南芥（Anacardium othonianum））喷雾干燥对翼龙（Pterodon emarginatus）水果精油（OE）的微囊化Rizz。）和麦芽糊精（M）作为墙面材料。微胶囊呈现出具有不规则和粗糙表面的颗粒，其通过X射线衍射证实，其干直径为57％，范围为0至1μm。热重分析法显示出一种热稳定的封装材料（峰值在301°C和429°C），而封装的核没有损失。Zeta电势（ζ= − 0.18 mV）证明了该材料的两亲能力。OE：腰果PEJU：M（w / w / w）的比例为1：3：3.6（w / w / w），在相同比例的β-石竹烯保留下，包封效果最佳（75％的收率和6.25％的OE保留）。巴西Cerrado腰果PEJU是用作微胶囊壁材的有前途的来源，尤其是在保护Emarginatus果实的OE中，以替代其他树胶，例如阿拉伯树胶。
