ROSELLE (HIBISCUS SABDARIFFA) ANTHOCYANIN USE IN MONITORING MEAT FRESHNESS

This study designed a new type indicator with hydrophobic Polyvinylidene Fluoride (PVDF) film as a moisture prevent-layer. And the sensor layer was provided based on polyvinyl alcohol/Sodium alginate (PS) and Roselle anthocyanins (RAs). Physical properties, microstructure, and color stability of t...
