- •
Bacterial celluloce (BC) nanofiber membrane was used as pH indicator label.
- •
BC labels were incorporated with red cabbage anthocyanins in two dilutions.
- •
Diluted anthocyanins had no effect on morphological and structural properties of BC.
- •
BC labels containing diluted anthocyanins was more sensitive to pH variations.
- •
BC-diluted anthocyanin label can be used as a visual smart packaging of foods.
