title: Titrimetric determination of calcium in mechanically separated poultry and beef: collaborative study.
abstract: A collaborative study was conducted on a titrimetric EDTA method for the determination of calcium in mechanically separated poultry and beef tissue. Six laboratories analyzed, as blind duplicates, 5 poultry samples and 5 beef samples. Calcium concentrations covered the levels from 0.04 to 0.82%. Pooled standard deviations were 0.0165 for repeatability, 0.0072 for bias, and 0.0225 for reproducibility. The method has been adopted official first action.
