Optimization of the shelf life of lamb forelegs packed in different multilayer polymeric materials and modified atmospheres.


ABSTRACT: Lamb forelegs were packed in three different gas mixtures (Treatment N2: 70% N2-30% CO2; Treatment O2: 70% O2-30% CO2; Treatment Ar: 70% Ar-30% CO2) and two types of polymeric materials (B1, a polyamide-polypropylene bag and B2, a bag made of bio-oriented polyamide, aluminium and polyethylene). Physical, chemical and microbiological parameters were determined, initially and after 7, 14 and 21 days of storage (3?±?1 °C). Colour and oxidative stability decreased and the number of microorganisms increased significantly during the storage period. Treatment O2 increased a* and TBARs. Despite the different permeability to O2, shown by the polymeric material (
