The aim of this paper was to evaluate the preservation of fresh strawberries packaging in: (i) high oxygen atmosphere (AAO) in equilibrium modified atmosphere (AME) packages (permeable film), (ii) AAO packages in AME with a ethylene adsorbing packaging material, (iii) macroperforated packaging (air) which was taken as reference. For AME packages a permeable packaging film with a selective permeability for oxygen and carbon dioxide. Storage temperature was 7°C. The gas mixture composition was 95% oxygen and 5% nitrogen. Counts of yeast, lactic-acid bacteria and psychrotrophic total anaerobic microrganisms were followed. The loss of weight due loss of moisture, spoilage by Botrytis or other mould and visual defects were evaluated. At third day the loss of visual defects was higher 10% in fruits packaged in AME.

The aim of this paper was to evaluate the preservation of fresh raspberries packaging in: (I) high oxygen atmosphere (ACO) in equilibrium modified atmosphere (AME) packages (permeable film), (II) ACO packages in AME with a ethylene adsorbing packaging material, (III) macroperforated packaging (air) which was taken as reference. A permeable packaging film with a selective permeability to oxygen and carbon dioxide was employed in AME packages. Storage temperature was 7°C. The gas mixture composition was 95 % oxygen and 5 % nitrogen. The weight loss due moisture loss, Botritis or another type of moulds and defects were evaluated. The latter's were higher than 10 % in five days. Oxygen and carbon dioxide concentrations did not reach harmful levels for the fruits. The adsorbing film did not produce diminishing on the ethylene concentration. [ABSTRACT FROM AUTHOR]
