    Abstract:
    Biogenic amines (BAs) are natural components of food produced mainly during metabolism in animals and plants. The determination of BAs is important because of their potential toxicity and their potential use as food spoilage indicators. In the present study, a method for the determination of six BAs (putrescine, cadaverine, histamine, β-phenylethylamine, tyramine, and tryptamine) by Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS) with Atmospheric Pressure Chemical Ionisation (APCI) source has been used on trout samples (Salmo trutta) stored in ice for 15 days. The results showed that on day 15 quite large amounts of putrescine (76.530 mg/kg), cadaverine (85.530 mg/kg), tryptamine (25.210 mg/kg), and histamine (15.975mg/kg) were detected, while the other BAs remained low (β-phenylethylamine: 3.230 mg/kg, tyramine: 0.165mg/kg). Furthermore, microbiological data (Total Vial Count- TVC, Pseudomonas spp, and Shewanella putrefaciens) showed that trout samples became organoleptically unacceptable on day 12, while volatile compound analysis showed a significant increase in total amounts of alcohols, aldehydes, and ketones on days 12 and 15.
