A new and fast continuous method for the pre-treatment of dehydrated broth for total creatinine determination

The quantification of total creatinine contributes to the quality control in meat products. The reference method for dehydrated broths treatment is tedious and takes approximately 6 h. A fast, simple and relatively safe procedure to the pre-treatment of these samples was developed by using a focussed microwave oven which works in continuous way. The optimization of the different variables for the pre-treatment was made and the validation of the method was carried out in order to ensure the accuracy of the obtained results.
