Abstract

Objective:For the determination of nitrite in meat and meat products.Methods:A new ultraviolet spectrophometric method for the determination of nitrite was proposed,which is based on the phenazone-nitrite reaction,producting nitroso-phenol,in the Hydrochloric Acid.the nitrite content was measured at 350 nm.Results:Nitrite in the linear concentration range of 0 mg/L～10 mg/L was determined with a detection limit of 0.29 mg/L.Conclusion:The method has been applied to the determination of nitrite in meat and meat products with satisfactory results.
