Effect of storage conditions on the biogenic amine content in wild boar meat
Hygienic quality of game meat depends on many factors during and after hunting. Freshness of meat is connected with the concentration of biogenic amines which is related to meat spoilage. The aim of this study was to assess changes in concentration of biogenic amines in raw meat of wild boar (n = 20, mean age 1–2 years) during storage at different temperatures. Carcases of wild boars hunted in winter 2012 in hunting districts of south Moravia were stored unskinned during 21 days at various temperatures (0, 7 and 15 °C). Concentrations of biogenic amines (putrescine, cadaverine, tyramine, tryptamine, phenylethylamine, histamine, spermine and spermidine) were determined in the shoulder and leg muscles by high-performance liquid chromatography in combination with triple quadrupole tandem mass spectrometry. Good hygienic quality was maintained when wild boar carcasses were stored for a maximum of 14 days at 0 °C (content of biogenic amines in 3 meat samples exceed the limit of 5 mg/kg on day 21 of storage) or a maximum of 7 days at 7 °C (content of biogenic amines in 4 meat samples exceed the limit of 5 mg/kg on day 14 of storage). The temperature of 15 °C should be considered as unsuitable storage temperature if good hygienic quality of game meat during storage is to be guaranteed (content of biogenic amines in 2 meat samples exceed the limit of 5 mg/kg already on day 7 of storage). The study brings new information about the biogenic amine content and its changes in wild boar meat during the storage period of 21 days.
