Insoluble And Dispersible Protein And Dye-Containing Particles For Use As Colorants
Inventors: Richard Hartel, Hassan Firoozmand
Colorant particles made from an insoluble protein-based substrate to which a dye is adsorbed are disclosed. The colorant particles are highly dispersible onto solid surfaces or within liquid systems, and thus can be used as substitutes for the alumina-based lake particles that are conventionally used as colorants in consumer products, such as food or beverage products, cosmetic products, pharmaceutical products, nutraceutical products, or toys.
