Food quality safety traceability technology and its application system development are worldwide focus and hot topic. Based on the literature review, the important meaning of food quality safety traceability technology was presented. The significance, development tendency and the main characteristic were summarized from four aspects: traceability unit dividing, information collection, information transformation, and information processing. The result showed that traceable unit in food quality safety traceability technology was developed from experienced dividing to model optimization, information acquisition technology was improved from manual collection to intelligent collection, information transmission technology was changed from independent to standardized transmission, and information processing technology was changed from manual analysis to intelligent decision.
