Popis:	Determination of salt in oysters by direct titration of the chloride ion, using 0.171N silver nitrate and dichlorofluorescein as an indicator, was compared to the AOAC back titration procedure. The direct titration method was easier to perform and far more rapid than the AOAC procedure and could be done in-plant. No significant differences were observed between the methods; however, the direct titration method was more reproducible at salt concentrations of less than 0.5%. The standard deviations were much greater for the AOAC procedure at low salt concentrations but were similar at higher salt concentrations.
