摘要：

Starch-ferulic acid (FA) composites have been developed for medical and food fields, while little focus is caused on their use in functional products by 3D printing. In this work, dynamic high-pressure microfluidization was employed to treat starch at various concentrations, for preparing modified starch-FA composites. The highperformance liquid chromatography results showed that an increased starch concentration was conducive to a high yield of composite with enhanced binding of FA. Compared with pure starch and starch-FA mixture gel, the starch-FA composite gel possessed lower viscosity, with a dramatically reduced extrusion pressure in the 3D printing test. Furthermore, antimicrobial activity tests indicated that the starch-FA composite gel can inhibit the growth of microorganism for achieving a long storage period. Overall, we provide a biomaterial of starch-FA composite that can serve as both a 3D printing food ink and an edible, printable, active, and lightweight packaging ink.
