Title

The impact of long-term storage of processed meat products under varying conditions on the microbial contamination and intramuscular fat deterioration

Abstract

The objective of the investigation was to evaluate the bacterial contamination and storage-induced changes in the lipids of smoked meat products stored in an non-barrier parchment package. Meat products (ham, collar, streaky bacon) have been stored as cured semi-products at a near cryoscopic temperature (-3ºC) for 4 weeks and at a temperature of -18ºC for 4 and 8 weeks. Additionally, the experimental material has been stored as a final product at a temperature in two different ranges (-3ºC, -18ºC), for 4 and 8 weeks. After the storage, semi-products were smoked and scalded. The bacterial pollution of smoked meat products was once more evaluated after the additional seven-day storage in a refrigerator (3ºC). The investigation results of the meat products stored 4 and 8 weeks at a near cryoscopic temperature and under the freezing conditions do not confirm the appearance of any pathogens, no pathogens were found in those products after the additional 7 day storage in a refrigerator (3ºC) either. The eight-week storage of meat products at a cryoscopic temperature or under the freezing conditions do not cause any substantial disqualifying oxidation and hydrolytic changes in lipids.
