Title:	Stabilized cooked cured-meat pigment
Abstract:	An encapsulated powdered cooked cured-meat pigment (PCCMP) is provided herein. Such pigment comprises a mononitric oxide complex of protoporphyrin (IX) Fe (II) compound derived from red blood cells, or from a hemin intermediate, or from a derivative thereof. The pigment is encapsulated within a treating mixture consisting of: (i) a carbohydrate-based wall material selected from the group consisting starch, modified starches, a starch polymer, a starch derivative, maltodextrins, starch products, chitinous compounds, .beta.-cyclodextrin and modified .beta.-cyclodextrin; (ii) a binding agent selected from the group consisting of gums and glycerin; and (iii) an additional agent comprising a reducing agent, a sequestrant or mixtures thereof.
