Abstract

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.
