The effect of nitric‐oxide myoglobin (MbNO) on lipid oxidation was studied in linoleate and β‐carotene‐linoleate aqueous model systems and compared with that of metmyoglobin (MMb) and oxymyoglobin (MbO 2 ) in short‐ and long‐term reactions. While MMb and MbO 2 had a clear prooxidative effect, MbNO, under the same conditions, acted as an antioxidant. The specific antioxidative activity of MbNO was maintained even in the presence of prooxidants such as hemeproteins. The significance of the conversion of MbO 2 and MMb into an antioxidant during the curing process is discussed.
