ABSTRACT
The value of the volatile basic nitrogen of meat is an important index to determine the freshness of meat. It is difficult to meet the demand of fast and non-destructive measurement by means of classical semimicro-quantitative nitrogent method. A model to predict the value of the volatile basic nitrogen based on near-infrared reflectance spectroscopy was established. Cluster analysis methods were applied to deal with the data of NIRS. If the content of TVB-N is more than 11. 6 mg x (100 g)(-1), the back pork may be rotten. The result shows that using NIRS could indicate the freshness of meat quickly and non-invasively.
