Lactose-derived caramel for sustainable industrial dye applications
This innovative solution utilizes lactose-derived caramel as a sustainable dye for industrial applications. By leveraging natural color compounds, it offers an eco-friendly alternative to synthetic dyes for use in food, cosmetics, packaging, and textiles.
Overview
The proposed solution introduces a novel use of lactose-derived caramel as a sustainable dye for industrial applications. This approach utilizes the natural browning compounds found in burnt sugar, enhanced with phenolic compounds, to create a dye with unique color characteristics. Unlike traditional synthetic dyes, this lactose-derived caramel offers an environmentally friendly option due to its natural origins and potential for use in a variety of applications, including food, cosmetics, packaging, and textiles.
Technical specifications
- Natural color compounds: Utilizes degradation compounds such as acetylfuran and furfural which provide inherent color properties.
- Phenolic enhancement: Incorporation of phenolic compounds increases browning intensity and provides antioxidative properties and heat stability.
- Versatile applications: Suitable for use in food and cosmetic formulations, as well as in textiles and packaging, demonstrating color stability and binding properties.
- Physicochemical characterization: Includes pH sensitivity, color strength, and electrostatic properties using advanced techniques like atomic force microscopy.
Technology readiness level
The technology is currently at TRL 4, having been validated in lab environments. Future plans include further testing and characterization in various applications over the next 18 months, focusing on material sourcing, caramel synthesis, and application testing in diverse industries.
