title: Distribution, Identification, and Quantification of Residues after Treatment of Ready-To-Eat Salami with36Cl-Labeled or Nonlabeled Chlorine Dioxide Gas.
abstract: When ready-to-eat salami was treated in a closed system with36Cl-labeled ClO2(5.5 mg/100 g of salami), essentially all radioactivity was deposited onto the salami. Administered36ClO2was converted to36Cl-chloride ion (>97%), trace levels of chlorate (<2%), and detectable levels of chlorite. In residue studies conducted with nonlabeled ClO2, sodium perchlorate residues (LOQ, 4 ng/g) were not formed when reactions were protected from light. Sodium chlorate residues were present in control (39.2 ± 4.8 ng/g) and chlorine dioxide treated (128 ± 31.2 ng/g) salami. If sanitation occurred under conditions of illumination, detectable levels (3.7 ± 1.5 ng/g) of perchlorate were formed along with greater quantities of sodium chlorate (183.6 ± 75.4 ng/g). Collectively, these data suggest that ClO2is chemically reduced by salami and that slow-release formulations might be appropriate for applications involving the sanitation of ready-to-eat meat products.
