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 the bi-layer indicator have been
investigated. The Water contact angle (WCA) of PS/RAs/ PVDF film (PSRF) was 108.85?, which can be
considered as an excellent hydrophobic surface. The lowest Water Vapor Permeability (WVP) value of PSRF
exhibited a good barrier property for moisture. Therefore, PSRF film was used to monitor the griskin freshness.
The Total volatile basic nitrogen (TVB-N) level was increased to 18.02 mg/100 g at 72 h, and the color of the
indicator presented visible color changes. The acquired results revealed a good correlation between TVB-N, pH
and color change of the indicator. The research indicated that PSRF indicator has increasing potential application
on food intelligent packaging
