Qualitative Determination

Histamine is produced by the bacterial decarboxylation of histidine, an ammino acid present in large amount especially in scombroid fish such as tuna. Fish containing high levels of histamine have been associated with many instances of “scombroid poisoning”. Since histamine is heat resistant, its presence has been used as an indicator of the good manufacturing practice and of the preservation state of canned tuna. In this study we have applied a rapid screening method to determine the presence of histamine in canned tuna marketed in Sardinia (Italy). A total of 165 samples of canned tuna were screened for the qualitative determination of histamine by HistaSure™ Fish Rapid Test. The results were consistently in agreement with the food safety criteria (<100 mg/kg of histamine) laid down in EC Regulation 2073/2005 (as amended). The HistaSure™ kit was confirmed as a rapid screening method for the presence of histamine in canned tuna.

Rapid Screening Method

Abstract A rapid screening method using X-ray fluorescence spectrometry has been developed for the detection and semiquantitative estimation of brominated vegetable oils in soft drinks. This method and a quantitative GLC technique have been applied to the determination of the brominated oil content in a wide range of soft drinks. Of 46 drinks examined, 23 contained brominated vegetable oils at levels between 7 and 85 mg/10 fluid oz of drink.

Abstract The described method should be of value as a rapid Screening process to eliminate serum containing a nonphysiologic high amount of iodine, thereby preventing contamination of other samples in the ashing oven. The advantage over other published methods is that it does not require special reagents or special equipment. The sensitivity is in the range of 300-400 µg. and total time required about 15-20 minutes.
