Abstract: In this study the nutrition value of Tianyuan Jiangyuan soybean paste was determined by following parameters: moisture content, total acid, pH, water-soluble carbohydrate (WSC), organic carbon (OC), crude protein (CP) and amino-acid nitrogen. Results showed that the moisture content increases at first, and then decreases stably. The content of total acid increases stably, and its concentration is up to 3.13% in final soybean paste. The contents of OC and WSC remain declining, and their concentrations are down to 483.99 g/kg and 57.32 g/kg in final soybean paste respectively. As for CP, it decreases after stable increase , and its concentration is down to 24.61% in final soybean paste. The content of amino-acid nitrogen keeps increasing during the whole progress, and its concentration is up to 49.2 g/kg in final soybean paste.
