This paper prepares a new kind of anthocyanins/shikonin/polyacrylic‐starch porous sheet with high acid or alkaline gas responsiveness, the high pH sensitivity Lycium ruthenium anthocyanins/shikonin is used as the pigment indicator, and the polyacrylic acid‐starch with cross‐linking interpenetrating and porous structure is used as the carrier, which is prepared by cross‐linking and monomer polymerization methods. Then the microstructure, thermal stability, and pH responsiveness of the anthocyanins/shikonin/polyacrylic‐starch porous sheet are characterized. It is applied to monitor the freshness of pork and shrimp finally.
