O2 absorbent system was evaluated on the inhibition of microorganisms growth in fresh lasagna pasta during storage at 10±2ºC. Fresh lasagna pasta was produced with and without potassium sorbate and acondicionated in high O2 barrier bags containing a O2 - absorber sachet in the head-space. Three treatments were obtained: pasta with potassium sorbate, pasta without potassium sorbate packed with sachet and pasta without potassium sorbate packed without sachet. In all treatments, the pasta were vacuum packed, randomly distributed at temperature of 10±2ºC and microbiologically evaluated for molds and yeast, Staphylococcus spp, total coliforms and Escherichia coli countings. All the treatments were effective in inhibiting the growth of the microorganisms evaluated during 30 storage days. The treatment using O2-absorber in the pasta without preservative, inhibition of 1 and 1.5 logarithmic cycles was observed for the molds and yeasts and Staphylococcus spp, respectively. No differences were observed among treatments for coliforms countings.
