In this study, spray drying mechanism was used to optimize the nanoencapsulation of iron and zinc using potato starch at constant proportion and variable maltodextrin and core material to keep the total solids of spray drier feed solution at 10, 20, 30 and 40% levels. Results exhibited that stable nanoencapsulates of iron and zinc were formed at 30% level with maximum in-vitro bioavailability and encapsulation efficiency of 90.68 and 89.36%, respectively. At this level the particle size and zeta potential of iron and zinc nanoencapsulates were 340.9 and 354.5 nm; 0.372 and 11.40 mV, respectively. Further, FTIR and XRD analysis of Fe 30 and Zn 30 nanoencapsulates exhibited that core material was successfully encapsulated by existence of functional groups and a semi-crystalline structure, respectively. Thus, study suggests the suitability of cheap carriers like potato starch and maltodextrin in successful encapsulation of iron and zinc indicating application potentiality in food fortification.
在这项研究中，喷雾干燥机制被用于使用马铃薯淀粉在恒定比例和可变麦芽糊精和芯材的条件下优化铁和锌的纳米封装，以保持喷雾干燥器进料溶液的总固体含量在 10%、20%、30%和 40%的水平。结果表明，在 30%的水平下形成了稳定的铁和锌纳米封装物，体外生物利用度和封装效率最高分别为 90.68%和 89.36%。在这个水平上，铁和锌纳米封装物的粒径和 Zeta 电位分别为 340.9nm 和 354.5nm；0.372mV 和 11.40mV。此外，Fe30 和 Zn30 纳米封装物的 FTIR 和 XRD 分析表明，通过存在的官能团和半晶态结构，芯材被成功地封装。因此，该研究表明了像马铃薯淀粉和麦芽糊精这样的廉价载体在成功封装铁和锌方面的适用性，表明了在食品强化方面的应用潜力。
