Abstract
Methods and apparatus are provided for decreasing the bacteria count of a food commodity without affecting its overall organoleptic quality (taste, odor, and color). This is accomplished using a treatment fluid comprising ozone, which is injected into a treatment chamber containing the food commodity. Some water is preferably added to obtain better contact of the ozone with the food by forming a thin film of ozonated water on the food surface. Spices and/or other ingredients may preferably be added with the water. The food is placed in a tumbler and the tumbler is set in motion. During treatment good contact between the treatment fluid and the food commodity is obtained by reversibly oscillating the tumbler. A log reduction of 40% or more in bacteria count may be obtained as compared without the ozone.
