Abstract In order to quickly determine the TVB-N in meat and meat products, the standard means of TVB-N in meat and meat products were improved. Such as: 1) TVB-N of mutton was analyzed by BUCHI –K360 type automatic azotometer; 2) Using Potassium carbonate as alkalescence reagent. The results showed that: 1) relative standard deviation(RSD) of improve means low 1% ; 2) Recovery and add Standard of improve means from 98.39% to l00.72%;3) improve and standard means t value 0.319< .The method was adequate for quickly determine the TVB-N of Meat and meat products.
