To evaluate the in vitro antimicrobial properties of active films containing Proallium®, a total of 13 strains including foodborne
spoilage and pathogenic bacteria were assayed in this study. Four
Gram-negative, 9 Gram-positive bacteria and 5 moulds and yeasts
were selected due to their relevance in the food industry. Most of
the microorganisms were purchased from the Spanish Culture
Collection (CECT) (Valencia, Spain). Moreover, the antimicrobial
activity of the film was evaluated in salad packaged with active
films testing total aerobic bacteria, enterobacteria, yeasts and
moulds.
