  • Patent number: 6423348
    Abstract: What is shown is an animal blood anticoagulant compound useful in the meat packing industry generally, and in slaughterhouse operations, particularly. The anticoagulant is effective when diluted with water at higher dilution ratios than earlier anticoagulants. In some field trials, this anticoagulant was at least as effective as previously known commercial anticoagulants when diluted by an additional 30%. The present anticoagulant preparation concentrate is an aqueous mixture of soft water (55.0%-65.0/%, w/w); tetrasodium ethylene diamine tetraacetate (Na4EDTA) (0.5%-3.0%, w/w); sodium hexametaphosphate (17.0%-24.0%, w/w); citric acid (5.0%-9.0%, w/w); and sodium hydroxide (4.0%-7.0%, w/w) to obtain a balanced pH that provides optimal chelating and anticoagulant activity. Optimal anticoagulant performance has been found to occur in the range of between pH 6.6 and pH 7.2.
