Abstract
Ammonia is first applied to a meat product to produce an ammoniated meat product. The ammoniated meat product is then contained in a treatment vessel in a treatment gas atmosphere substantially free of ammonia gas. Once the ammoniated meat product is contained in the appropriate atmosphere, the treatment method includes increasing the pressure in the treatment vessel to an operating pressure greater than the vapor pressure of ammonia at the temperature of the ammoniated meat product being treated. The operating pressure is held within the treatment vessel for an operating period effective to reduce the amount of ammonia gas which escapes from the meat product after the product is placed again under atmospheric conditions.
Claims20
A method for treating meat products with ammonia, the method including the steps of:
- (a) applying ammonia to a meat product to produce an ammoniated meat product;
- (b) containing the ammoniated meat product in a substantially ammonia free treatment gas atmosphere within a vessel;
- and
- (c) increasing the pressure of the treatment gas atmosphere to an operating pressure for an operating period sufficient to reduce an ammonia odor in the meat product after the meat product is removed from the vessel.
A method for treating whole meat products with ammonia, the method including the steps of:
- (a) applying ammonia to a whole meat product to produce an ammoniated whole meat product;
- (b) containing the ammoniated whole meat product in a treatment vessel;
- (c) developing a substantially ammonia free treatment gas atmosphere in the treatment vessel;
- and
- (d) increasing the pressure of the treatment gas atmosphere in the treatment vessel to an operating pressure for an operating period sufficient to reduce an ammonia odor in the whole meat product after the meat product is removed from the vessel.
A method for treating meat products with ammonia, the method including the steps of:
- (a) applying ammonia to a meat product to produce an ammoniated meat product;
- (b) placing the ammoniated meat product in a substantially ammonia free treatment gas atmosphere;
- and
- (c) increasing the pressure of the treatment gas atmosphere to an operating pressure greater than the vapor pressure of ammonia at the temperature of the meat product for an operating period of at least one second.
