The use of plastic film (biorented polyprolylene) under cold conditions to storage ‘Rainha Claudia Verde’ plums.    To increase the consumption period of ‘Rainha Claudia verde’ plums with good level of quality using simultaneously cold storage and plastic film is the general propos of this research work.

Bags of Biorented polyprolyline, (PplusÒ) were used for packing samples and there were also control samples witout any kind of plastic bag.The fruits were stored at 2 °C of temperature and 95% RH.At predetermined days (0, 7, 14, 21, 28, 35, 39, 42 and 49) samples (10 fruits of each) were removed from cold chambers and tested.The tests carried out were: Weight Loss, External Colour (L* a* b*), Visual Aspect of the epidermis, Epiderm puncture Test, Mesocarp Penetration Test, Soluble Solids Content, Titrable Acidity (% Malic Acid).It was used “Statistica 6.0” program and an Anova analysis with two factors: “Storage Time” and “Packing Modality”.

Biorented Polyprolylene (PplusÒ) is appropriate to minimize the loss of weight in the fruits storage at 2 °C and 90% RH.The textural properties and visual aspect, allow to conclude that to storage plums ‘Rainha Claudia Verde’ using bags of PplusÒ is very adequate however the values of SSC don’t reach the level observed in the fruits from control samples.At these conditions, o­nce more, ‘Rainha Claudia Verde’ plums have shown no advantage in being stored for more than 42 days.
