Spray Drying of Indigo water soluble

Indigo is a natural dye that has been used for centuries to color textiles. In recent years, there has been an increasing interest in using indigo in a variety of applications, including cosmetics, food, and pharmaceuticals. However, one of the challenges in using indigo is its limited solubility in water, which can hinder its use in certain applications.

Spray drying is a potential solution to this problem. By converting indigo into a water-soluble form and then spray drying it, the resulting powder can be easily incorporated into a wide range of products. The spray-dried indigo powder can be used as a natural blue food colorant, a cosmetic ingredient, or a pharmaceutical excipient.

Spray drying of indigo requires careful optimization of several parameters, such as the type of carrier material, the drying temperature, and the concentration of the indigo solution. The resulting powder should have good solubility in water, a consistent color, and stability over time.

Overall, spray drying of indigo offers a promising approach to expand the use of this natural dye in various applications, providing a water-soluble form with improved functionality and versatility.
