The Histamine Check Swab is to be used to assay histamine contained in food samples by means of a colorimetric reaction. Assay results can be checked by the changes in reagent color. Comparing changes in color with the color chart will provide a rough understanding of histamine content.
The assay method of this product incorporates enzymes that act specifically on histamine. In the presence of tetrazolium salt and electron acceptors, histamine dehydrogenase acts on tetrazolium salt to produce formazan dye (purple). As formazan dye concentration varies depending on histamine concentration, a rough understanding of histamine concentration in sample can be obtained by making a comparison with the color chart.
This product simplifies the process of identifying histamine concentration in assay samples, but it is neither intended as a precise quantification of histamine or an official analytical method.
