Investigations on shelf life and shelf life assessment of raw meat - Formation of biogenic amines and microbial changes during storage

Aim of this study was to assess the contents of biogenic amines and microbiological and sensory evaluation of fresh raw meat until the expiration data. Of 102 samples, objections were raised to 28, to 10 of them even before the expiration date. Sensory and microbiological assessment of objected samples agreed to >95%. High concentrations of biogenic amines (putrescine up to 57 mg/kg, cadaverine up to 140 mg/kg, tyramine up to 74 mg/kg, spermine up to 210 mg/kg) were found only in samples with high total aerobic counts and obvious sensory deterioriation.
