Intelligent <scp>pH</scp> indicator films containing anthocyanins extracted from blueberry peel for monitoring tilapia fillet freshness

Abstract

It can be concluded that the color changes of TG/PVA/BPE films were corresponded with TVB-N and TAC values of tilapia fillets, which presented great potential as a visual package label to monitor fish freshness at ambient and chilled temperatures. © 2020 Society of Chemical Industry.
