| Abstract: | A method for the determination of ammonia nitrogen in distillers grains by spectrophotometry had been established. It was used to measure the content of ammonia nitrogen in distillers grains before and after the distillation of Zhimaxiang Baijiu. The relative standard deviation(RSD) of ammonia nitrogen was 2.81 % to 3.85 %, and the recovery rate was 101.31 % to 104.45 %. This method has the characteristics of simple operation, good precision and high accuracy, and it could be used for daily detection of ammonia nitrogen in distillers grains and for guiding the production of Zhimaxiang Baijiu. |
