Development of natural dye based biodegradable colourimetric intelligent packaging sensor labels
Colourimetric indicators were prepared using anthocyanins, poly(vinyl alcohol) and cellulose nano-fibre by the electro-spinning technique. The indicator label containing 2000 ppm anthocyanin was found to be the optimal dye concentration. Fourier-transform infrared spectroscopy and X-ray diffraction...
