Abstract
The pigment responsible for the color of cooked cured-meats has been prepared from red blood cells, directly or indirectly through a hemin intermediate. The process for preparing this pigment includes reacting bovine or hog red blood cells with a nitrosating agent and a reductant, at elevated temperatures, to provide a cooked cured-meat pigment; stabilizing and/or encapsulating and/or protecting the cooked cured-meat pigment to provide a stabilized cooked cured-meat pigment; and drying the stabilized cooked cured-meat pigment by spray-drying, drum-drying or freeze-drying techniques. As an essential feature of this invention, the pigment is encapsulated in carbohydrate-based wall materials for easy handling. The stabilized pigment, when added to meat prior to cooking, reproduces the typical color of a nitrite-cured meat product.
