Abstract： Objective： To evaluate the quality status of commercially available soy sauce in Yulin city by analyzing thecontentofamino acid nitrogen，ammoniumsalt，and total nitrogen in high salt dilute soysauce.Method： 26 batches of soy sauce samples were randomly collected from major supermarkets in Yulin city，and the three key quality indicators of aminoacid nitrogen，ammonium salt，and total nitrogen content in soysauce were detected and analyzed. Result： The amino acid nitrogen content of 26 high salt dilute soy sauces ranged from 0.58g/100mL to 1.50g/100mL ; the ratio of ammonium salt to amino acid nitrogen is less than 30% ; the total nitrogen content ranges from 1.01g/100mL to 2.10g/100mL . There is a significant correlation between the content of amino acid nitrogen， ammonium salt，and total nitrogen inhigh salt dilute soysauceandits grade.There is apositivecorrelation between amino acid nitrogenand total nitrogen in high salt dilute soysauce，and samples with highertotal nitrogen content also have higher amino acid nitrogen content. Conclusion：This study analyzed the content and proportion relationship of three physicochemical indicators，namelyaminoacid nitrogen，ammoniumsalt，and total nitrogen，inhigh salt dilutesoysauce，providing areliable quantitative basis for food safety regulatory authorities to implement precise and scientific supervision.

Keywords： high salt dilute soy sauce; amino acid nitrogen; ammonium salt; total nitrogen
