Design of Material Code for Food Traceability System

The Food Traceability System is an effective solution for food safety problems,its key function is to record,transmit and query the traceability information.The traceability information takes the traceability code as a carrier,and it′s a kind of material code which differs to conventional ones.The coding principles of Food Traceability System were introduced.Based on the analysis of existing material code system and traceability system application demands,a feasible solution for the coding of traceability code was put forward.
