International ClassesA23B 004/16A61L 002/00 AbstractMethods 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.Field of SearchApplied material is biocidal or disinfectingTreatment of food material by addition of material other than water, air, carbon dioxide, nitrogen or inert gases, or mixtures thereof Including gas-liquid contact Using disinfecting or sterilizing substance With positive pressure or vacuum Including rotating member Apparatus for treating solid article or material with fluid chemical Including means for adding a material to a gas | |
