  • Publication number: 20130156907
    Abstract: A process for sanitizing objects is comprised of the steps of: (1) contacting the object with a dry fog in an enclosed sanitization zone wherein the dry fog is comprised of droplets having a diameter of 4-5 microns and wherein the droplets comprise an aqueous solution of a sanitizing agent for a time sufficient to produce a substantially dry sanitized object and a residual amount of dry fog; (2) removing the substantially dry, sanitized product from the enclosed zone while simultaneously removing the residual dry fog and passing the residual dry fog through a treatment zone whereby unreacted sanitizing agent is removed from the dry fog. The disclosed process yields substantially dry sanitized objects that do not require rinsing with water.

  • Patent number: 5026565
    Abstract: A process for the removal of sterols and/or lipid components (e.g., cholesterol and fats) from lipid containing food (e.g., meat) using sub or super-critical fluids (e.g., CO.sub.2) involves initial processing of the food to produce an intermediate moisture product in which substantially all of the "free water" but not all of the "bound water" is removed. Different moisture removal techniques may be used. Where freeze drying of food flakes is adopted the moisture level is preferably reduced to 30-55% w/w. The intermediate moisture product is treated with supercritical CO.sub.2 to remove the lipids therefrom. Optionally the cholesterol can be separated from the fat component by use of an absorbent to selectively remove the cholesterol from the supercritical CO.sub.2. The product can be reconstituted with water and fat to provide a reconstituted meat product suitable for hamburgers.

    Abstract: In chilling freshly slaughtered hog carcasses the bleaching effect of a bactericidal spray is eliminated by the use of chlorine dioxide in a concentration sufficient to inhibit the protein synthesis mechanism of bacteria. The concentration required for this purpose, which may be in the range of 5 to 25 parts per million (ppm), is so small that it produces very little if any oxidation; hence the characteristic bleaching effect of chlorine dioxide is avoided. The skin color of carcasses so sprayed is unaffected by the process.
