Anthocyanin based sensory pad for determination of chicken meat spoilage

Production and consumption of chicken meat has increased considerably with the increasing world population, and will continue to increase, due to its health benefits and its economic value. Chicken meat is a sensitive food due to its characteristics and microbiological load. Traceability is very important to increase food safety and biosecurity. Freshness indicators are often used to monitor the presence of metabolites produced by microorganisms, mostly functioning through the colour change of the indicator. A developed natural, edible, biodegradable, purple coloured pH sensitive sensory pad was put inside a chicken meat package to observe the chicken meat spoilage with colour change due to pH changes in the meat.
