Abstract The preparation of monodisperse Pickering emulsions currently can only be achieved using microfluidics or membrane emulsification, limiting its widespread applications in many fields. Here, by simply introducing naturally occurring pollen grains during mechanical it becomes extremely feasible to fabricate uniform emulsions. process shearing and turbulence leads a constant reduction the size droplets dispersed phase. robust exine continuous phase enables them retain their structural integrity resulting formation single pollen‐in‐water‐in‐oil structure. Meanwhile, intrinsic monodispersity allows for similarly uniform, they easily collected through centrifugation. As result, this novel methodology achieves effective formulation an unprecedented way. Furthermore, utilization sporopollenin capsules (SECs) as replacement pollen, conjunction with sol–gel interfacial engineering, attainment “yolk‐shell” dual‐shell microcapsules. This approach not effectively addresses issue cargo leakage SECs but also imparts exceptional uniformity stability
