Abstract: In this paper, quality of chilling beef was evaluated after processing with bacteria reducing methods by ultraviolet radiation, ultrasonic and modified atmosphere packing. All detecting items for these samples processed covered color, extracting, pH, holding water capacity, ratio of cooked loss, TVB-N, colony-forming unit and coliform bacteria. At 0 ̄4℃, the results of the seventh group (mixture gases rate: CO2:O2:N2=2:1:1) indicated that the formula had the longest storage time of 22d for chilling beef among the whole groups. Moreover, the tenderness of beef with ultrasonic processing was improved in comparison with blank groups.

Key words: chilling beef, ultrasonic, modified stmosphere packing, preservation
