Abstract:
A method for separating lean meat from lean meat-containing material includes combining a particulate material with fluid, subcritical carbon dioxide at a pH of about 7 or less and a pressure of about 600 psig. The material and fluid is introduced into the vessel and is separated into low density and high density fractions. The material from the low density fraction is removed via an outlet and has a higher percentage of fat than the material introduced into the vessel. The material from the high density fraction is removed via an outlet and has a higher percentage of lean meat than the material introduced into the vessel. The vessel can include a centrifuge or a vessel disposed toward the vertical having an upper and lower outlet, wherein the separation is achieved by the respective densities of the material, and the natural or an artificial gravity field.
Abstract:
Embodiments of the invention generally provide methods and systems that distribute an additive in solid carbon dioxide in an interior of food processing equipment. The additive may be injected into a flow of liquid carbon dioxide upstream of an expander at or adjacent to the interior. Injection of the additive into the interior may be alternated with directing a flow of expanded carbon dioxide into the interior. In some embodiments, the freezing point of the additive with or without a diluent composition and/or additive(s) is lower than a temperature of the liquid carbon dioxide.
Abstract:
Disclosed is a method for improving decontamination in meat, poultry, fish, fruit and vegetable processing using a combination of acid(s) and peroxy compound(s). The method comprises a “stacked” approach, sequentially adding the acid(s) and peroxy compound(s) to an aqueous stream to provide a point-of-use low-pH antimicrobial composition that is highly effective for decontamination of food products, as well as safer for use in a processing facility.

Abstract:
The present invention relates to methods for reducing microbial contamination on carcass, meat, or meat product; or on surfaces used in processing the carcass, meat, or meat product; employing compositions including medium chain peroxycarboxylic acid, and to the compositions. The methods include applying a medium chain peroxycarboxylic acid composition to carcass, meat, meat product or surface.
Abstract:
Fuels used may be derived from existing waste streams such as animal wastes and streams of discarded or unwanted animal byproducts generated at animal slaughterhouses. A method of processing organic waste products into fuel includes homogenizing the waste products. The waste products are heated and pressurized. Water is removed from the waste products. Selected constituent of the waste products are separated from the waste products into a waste stream. The waste stream is blended with a fuel to form a bio-fuel mixture.
Abstract:
The present invention relates a method of preventing the browning or darkening in fish so as to provide fish having color which is the same as that of the freshly caught fish. The present invention also relates to a method of preparing food from such fish.
Abstract:
A food product having on its surface at least one substance that reacts with a sanitizing compound to be applied to the food product is sanitized by applying an aqueous prewashing liquid to remove at least a portion of said substance and then applying an aqueous sanitizing liquid that contains ozone, each liquid being sprayed onto all exterior surfaces of the food product from a plurality of directions while moving the food product laterally with respect to the sprays, maintaining contact between said sanitizing liquid and said food product for at least a time effective to maximize wetting of the surface of the food product by the sanitizing liquid, and then removing mechanically at least 75% of the sanitizing liquid from said food product.
Abstract:
A method for producing a pH enhanced meat product includes injecting or otherwise forcing a pH modifying material into the interior of the meat product, either before, after, or concurrently with an oxygen enhancing material. The oxygen enhancing material may be combined or mixed with the pH modifying material to form an oxygen enhanced pH modifying brine. This brine is then forced into the interior of the meat product to effect the desired pH modification in the meat product.
Abstract:
A system and method are disclosed for increasing the concentration of hypochlorous acid in a quantity of water. Acid is injected into chlorinated water to decrease the pH of the chlorinated water. By decreasing the pH, the hypochlorite/hypochlorous acid equilibrium of the chlorinated water is shifted to increase the concentration of hypochlorous acid on the treated water.
