Research by Elizabeth Carvajal‐Millan and colleagues shows the electro‐sprayed core‐shell particles (2.9 mm diameter) of maize bran arabinoxylans (MBAX) with insulin in the core, and maize wastewater arabinoxylans (MWAX) with Bifidobacterium in the shell. Scanning electron microscopy revealed a porous (core) and a smooth (shell) microstructure. Confocal laser scanning microscopy confirmed the particles core‐shell structure and the viability of the probiotic entrapped. Under simulated gastrointestinal conditions these particles were not degraded in the stomach and small intestine, but released 76% of the carried insulin in colon. Insulin and Bifidobacterium encapsulation by electrospray could be feasible and adequate to produce arabinoxylan particles containing both insulin and probiotics. This cover article appears in J.
