Fluorometric determination of histamine in cheese

J Assoc Off Anal Chem. 1978 Sep;61(5):1092-7.

Abstract

Thirty-one samples of cheese obtained from retail outlets were analyzed for histamine, using an official AOAC fluorometric method. The types of cheese analyzed and the ranges of histamine found were: colby, 0.3--2.8; camembert, 0.4--4.2; cheddar, 1.2--5.8; gouda, 1.3--2.4; provolone, 2.0--23.5; roquefort, 1.0--16.8; mozzarella 1.6--5.0; and swiss, 0.4--250 mg histamine/100 g. Ten of the 12 samples of swiss cheese contained less than 16 mg histamine/100 g. The remaining 2 samples which contained 116 and 250 mg histamine/100 g were judged organoleptically to be of poor quality. An investigation of one processing facility showed that the production of histamine in swiss cheese may have been a result of a hydrogen peroxide/low temperature treatment of the milk supply. Recovery of histamine added to methanol extracts of cheese ranged from 93 to 105%. Histamine content was confirmed by high pressure liquid chromatographic analysis of the methanol extracts.
