Abstract

The shelflife extension by MAP and AP of a typical cheese tart was studied. Baked tarts were packaged inside barrier to gas trays and wrapped with a barrier to gas and water film. Four batches were prepared: 1) Control; 2) MAP with different N₂/CO₂ ratios (70/30 and 20/80); 3) Trays with an iron oxide-based oxygen absorber. Tarts were stored at 20°C and sampled for analysis at 0,7, 14,27,35 and 48 days. Determinations inc1uded microbioIogical analyses (total bacterial count, moulds, yeast and staphylococci), chemical-physical parameters (pH, water activity and dry matter), gas changes (CO₂, O₂ and N₂) inside MAP and AP trays, texture evolution and sensory analysis at our laboratories.
AP allowed a shelf life of 48 days, MAP shelf lives were of 14 and 34 days for 70/30 and (20/80), respectiveIy, while controI tarts spoiled after only 7 days.
