AI Technical Summary

Benefits of technology

The invention is a method and apparatus for sanitizing perishable goods by mixing them with a sanitizing fluid for a suitable period of time, separating the fluid, and neutralizing any residual sanitizing agent left with the goods. The sanitizing fluid can include ozone and water, and separation of the ozonated water can be facilitated by a squeezing effect or a centrifugal apparatus. The goods can also be treated with an antioxidant to reduce the deleterious oxidizing effects of ozone. The invention provides precise control of exposure time to minimized ozone concentration, sanitizing the goods without causing deleterious effects on them, and reducing exposure to oxygen.

Problems solved by technology

However, the present methods for using ozonated water to wash food products are for the most part conducted in open vats or in ambient environments wherein, the amount of ozone exposure is relatively uncontrolled.
However, widespread use of ozone has been hampered by the inability to properly control the amount of ozone exposure to the meat.
Ozone is a strong oxidizer and will render perishable goods, such as meat, unsuitable for consumption if the exposure time to ozone is not properly controlled.

Embodiment Construction

[0019] The aforementioned PCT application PCT / US01 / ______, filed Nov. 28, 2001, attorney docket No. CRSL-1-18064, is herein expressly incorporated by reference. Referring now to FIG. 1, a method for sanitizing perishable goods, including beef, is illustrated. As used in the present invention, sanitizer refers to an agent which will reduce pathogens and microorganisms to insignificant levels. In one instance, this may include the standard set forth in AOAC 4.020-4.029 (1984). Those chemicals which, at recommended concentration, produce 99.999% kill of 75-125 million E. coli (ATCC 1129) and 75-125 million S. aureus (ATCC 6538) within 30 seconds at 70-75° F. are considered satisfactory for purpose of using them in the present invention and can be called sanitizers. However, it is to appreciated that as standards changed, the sanitizer used in the present invention, can likewise change accordingly. Furthermore, it is to be appreciated that the method and apparatus may not meet the level...

Abstract

The invention is directed to a method and apparatus for sanitizing perishable goods by mixing the goods with sanitizing fluid for a suitable period of time followed by separating the fluid and substantially neutralizing any residual sanitizing agent left in the goods. In one instance, the sanitizing agent includes ozone and water, therefore separation of the ozonated water advantageously proceeds with a squeezing effect to more adequately remove the ozonated water from the goods.
