The encapsulation by spray drying of maize anthocyanins was evaluated using two types of wall materials, consisting of normal and waxy maize starch, which were esterified with octenyl succinic anhydride. The X-ray diffraction analysis revealed that SWMS possessed a completely amorphous, while SNMS had a crystalline structure. SNMS showed peaks at 2 = 13.1°, 19.8° and 22.4°. The results revealed that SNMS and SWMS had almost the same encapsulation productivity (EP); SNMS showed the best performance because its EP was higher (95%) than in SWMS (90%). The stability of microcapsules produced with SNMS showed the highest anthocyanin retention after storage in the water activity () range of 0.11-0.94 at 40 °C.
使用两种由经辛烯基琥珀酸酐酯化的普通玉米淀粉和糯玉米淀粉组成的壁材，通过喷雾干燥对玉米花青素的包封进行了评估。X射线衍射分析表明，SWMS具有完全无定形结构，而SNMS具有晶体结构。SNMS在2θ = 13.1°、19.8°和22.4°处出现峰。结果表明，SNMS和SWMS具有几乎相同的包封产率（EP）；SNMS表现最佳，因为其EP（95%）高于SWMS（90%）。用SNMS制备的微胶囊在40℃下于水分活度（aw）范围为0.11 - 0.94中储存后，显示出最高的花青素保留率。
