Thisparticularly holds when ascorbic or erythorbic acid is added inorder to enhance the release of nitric oxide from nitrite duringheating. Most of the added nitrite is present as NO bound withmyoglobin (5–15%), sulphydryl groups (5–15%), lipids (1–5%)and proteins (20–30%), partially is present as nitrate (<10%) andas nitrite (10–15%) [4,5]. Therefore, analytical methods usuallydetermine the residual nitrite/nitrate.
