Technical Advantages
Heat Resistance
Pasteurization, UHT, baking and extrusion — our heat-stable grades are engineered for the processes your products actually go through.
Heat accelerates pigment degradation. We counter this with micro-encapsulation in plant-based carriers, the addition of natural antioxidants and by choosing inherently robust pigments such as gardenia blue and paprika.
Heat resistance is reported as the highest temperature at which the product retains at least 85% of its initial color intensity after a typical processing hold time.
Test Method
Colorant in pH 6.5 model system, heated 30 min at set temperature, retention measured by absorbance at λmax.
