Emulsion formulations are commonly used in products that contain two immiscible components, such as oil and water. Natural food colorants are preferred ingredients to impart desired color tones and visual appeal to emulsions. For instance, natural colorants derived from sources like plant extracts, dried fruits, and vegetables can be used.

Suspension formulations involve the dispersion of solid particles in a liquid medium. Natural food colorants play a significant role in coloring such products. For example, natural colorants like plant powders, spices, seaweed extracts, among others, can be used to provide natural and appealing colors to suspensions.Incorporating natural food colorants into emulsions and suspensions requires attention to stability and homogeneity. Some colorants may exhibit challenges such as sedimentation or settling tendencies. Therefore, it is important to ensure stability by using stabilizing agents, emulsifiers, or dispersants in the formulations.
