Abstract:Penicillium glabrum, P. purpurescens, P. decumbens, P. expansum, P. chrysogenum, P. crustosum andP. aurantiogriseum are responsible for some of the alterations noticed on Moroccan table grapes cold stored. Contamination of these table grapes withPenicillium species occurs in the vineyard and inside the cooling station where other fruits which are often fungus-contaminated are also kept. All of thesePenicillium species were able to grow at 0°C apart fromP. glabrum andP. purpurescens. Consequently, refrigeration of grapes during long-term storage is not sufficient in itself in preserving their initial qualities.
Keywords:Cold storage  Penicillium  Table grape
