Stable natural color solutions for extruded food applications

Overview

This offering provides stable natural color systems for brown/red-brown, orange, red, and green extruded or puffed foods, supplied as powders or dispersible preparations. It is designed for food manufacturers seeking clean-label color solutions that withstand demanding processing conditions such as steam treatment, extended drying, and short high-temperature frying.

The solution is supported by completed application screening in a representative starch/flour puffed-food matrix, rather than relying on ingredient properties alone. Multiple natural pigment families—including red yeast rice, beet red, paprika, sorghum red, carmine, gardenia yellow, curcumin, beta-carotene, annatto, compound green systems, and coloring-food powders—produced differentiated red, red-brown, orange, yellow, and green outcomes after processing. This comparative portfolio allows weak candidates to be replaced with more suitable pigments or blends for the same target shade.

Technical specifications

Key features:

• Natural-origin color systems available as powders or dispersible preparations
• Screened across a starch/flour puffed-food model with colors incorporated during mixing, steam-heated, formed, dried at 70°C for 6–8 hours, and fried at 180–200°C for 10–15 seconds
• Portfolio includes red, red-brown, orange, yellow, and green pigment families for flexible shade matching
• Existing products are manufactured under defined specifications and can be supplied with technical and regulatory documentation

Application support:

• Selection and optimization of candidates for the customer’s specific matrix, extrusion temperature, moisture, and residence time
• Confirmation of dosage, color retention, labeling, and scalability through trials
• Bench screening to assess dispersion, initial color, and compatibility
• Process validation comparing CIE Lab* values, color retention, torque, throughput, expansion, texture, and sensory quality against an uncolored control
• Accelerated and real-time stability studies in intended packaging
• Scale-up support including specification confirmation, regulatory suitability, quality controls, pricing, lead time, and supply planning

Technology readiness level

The technology is at an advanced development stage. Application screening has been completed in a representative puffed-food matrix, demonstrating that multiple natural pigment families produce stable and differentiated color outcomes after steam treatment, extended drying, and short high-temperature frying. The next phase involves sponsor-specific extrusion trials to quantify color retention, optimize dosage and dispersion, and verify the best clean-label and cost-in-use option before scale-up and pilot or production batch support.
