Effect of blended colorants of anthocyanin and shikonin on carboxymethyl cellulose/agar-based smart packaging film.
Int J Biol Macromol. 2021 Jul 31; 183:305-315.IJ

Abstract

Natural colorants (anthocyanin and shikonin) were blended in different ratios (3:1 and 1:3) and used for the preparation of carboxymethyl cellulose (CMC)/agar-based functional halochromic films. The colorants were compatible with the polymer matrix and evenly spread over the polymer matrix. The addition of colorants slightly improved the mechanical strength and significantly improved the water vapor barrier properties of CMC/agar-based films without altering the thermal stability. The color indicator film exhibited excellent UV- barrier properties without substantially reducing the transparency. It also showed distinct pH-responsive color-changing properties in the pH range of 2-12, showing excellent acid and base gas sensing properties. The shikonin-added film showed potent antimicrobial activity against food-borne pathogenic bacteria, and the color indicator films exhibited intense antioxidant activities. The CMC/agar-based color indicator films with improved physical and functional properties are likely to be used in active and intelligent food packaging applications.
