Abstract
The main objectives of this work were to evaluate the chemical and microbiological fresh beef meat qualitypacked in aerobic atmosphere with biopolymers, to investigate the possible role of biogenic amines(BAs) as indicators of spoilage in fresh beef meat stored at 4 C for 8 days. The results of this researchhighlighted that for fresh meat packaging it could be possible to replace the PS tray/PVC film system, withan expanded PLA biopolymeric tray heat-sealed with a biopolymeric film, characterized by a negligibleenvironmental impact in comparison with the use of synthetic plastic materials. The storage time differentiatedthe meat samples on the basis of pH and microbiological characteristics. With regard to BAs,tyramine and cadaverine resulted strongly influenced by the storage time, and to a less extent putrescineand spermidine. Tyramine and cadaverine could be used as spoilage indexes of fresh beef meat chilledand packed in aerobic atmosphere with biopolymers.File | Dimensione | Formato | |
