Abstract:
The pH sensing biofilms include anthocyanin and a cellulose nanostructure or a cellulose nanocomposite. The cellulose nanostructure can include cellulose nanofibrils. The cellulose nanocomposite can include a composite of cellulose nanofibrils and pectin or a composite of cellulose nanofibrils and alginate. The presence of the anthocyanin in the biofilm allows the biofilm to change color in response to pH changes, thereby allowing the biofilm to be used as an active visual indicator of decay.

Claim (Index 14):
A method of manufacturing a pH sensing biofilm, comprising:\n extracting anthocyanin from  Petunia hybrida;  extracting cellulose nanofibrils from  Phoenix dactylifera;  preparing a nanocomposite including the cellulose nanofibrils; mixing the nanocomposite with the anthocyanin to provide a mixture; and sonicating the mixture to provide a sonicated mixture; and drying the sonicated mixture.
