In this study, halochromic smart films were produced, characterized, and applied to monitor
the freshness of hairtail and shrimp in real-time. Red cabbage anthocyanins (RCAs) solution …

Curcuma longa L. essential oil and anthocyanin extracts contain bioactive compounds such
as antioxidant properties and their pigments are able to change color when exposed to …

Today, smart indicators especially based on pigments and natural biopolymers have
developed significantly in laboratory and industrial scale. In addition to tracking the …

Sustainable multifunctional halochromic nanocomposite films (“smart films”) were prepared
using a casting method. Natural pigments (saffron or red barberry anthocyanins) and TiO 2 …

A new generation of eco-friendly packaging materials is required to improve food quality,
safety, nutritional value, shelf-life, and sustainability. In this study, a novel multifunctional …

A green nanocomposite film with pH-sensitivity and antioxidant activity based on oxidized
chitin nanocrystals (O-ChNCs)/gelatin incorporating black rice bran anthocyanins (BACNs) …

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 …

An on-package colorimetric label was fabricated using Hibiscus sabdariffa L. anthocyanin as
a freshness indicator because its color depends on pH. The anthocyanins were embedded …
