The perception of food, cosmetics, and pharmaceutical products is influenced greatly by colour. It signifies quality, freshness, and even the identity of the brand. Nevertheless, the challenges of storing and processing products while preserving the colour are immense. Colour fading and distortion due to heat, light, and oxygen exposure result in the loss of appeal and consistency of the product.
This is where the technology of microencapsulation enters. Colour molecules are enclosed within a protective 'shell' and manufacturers can ensure synthetic food colours against degradation, achieve extended shelf life as well as improved dispersion and controlled release; therefore, the end product retains its intended brightness and hue notwithstanding processing conditions, which means a game changer for industries that depend on colour performance.
For all brands, modern encapsulation and delivery systems, including spray drying, coacervation, and liposome encapsulation in food, beverage, cosmetic, and pharma applications, are facilitators of improved stability and uniformity. Synthetic colours and formulation efficiencies are in advance, while the cost of formulations is reduced.
