The most commonly used technique for water content determination is Karl-Fischer titration with electrometric detection, requiring specialized equipment. When appropriate equipment is not available, the method can be performed through visual detection of a titration endpoint, which does not enable an analysis of colored samples. Here, we developed a method with spectrophotometric detection of a titration endpoint, appropriate for moisture determination of colored samples. The reaction takes place in a sealed 4 ml cuvette. Detection is performed at 520 nm. Titration endpoint is determined from the graph of absorbance plotted against titration volume. The method has appropriate reproducibility (), accuracy, and linearity ().

Abstract Samples of grated milk chocolate were equilibrated with moisture at increased humidity levels. In the first part of the study, the moisture content of the samples was determined by using the alternative OICC method, manual Karl Fischer titration, and azeotropic distillation. In the second part of the study, the AOAC official method (13.002), azeotropic distillation, and an automated Karl Fischer titration were used for the moisture determination. The results show that the Karl Fischer titration method is more accurate, more precise, and much faster than either of the official methods tested. The azeotropic distillation method gives results that are comparable with those obtained using the Karl Fischer titration method but it requires much more time.
