Fruits were placed in hard perforated ethylenepolyterephtalate trays and stored at 1ºC and 11ºC and 70% RH. Four treatments were conducted and evaluationswere carried out every three days for 15 days. The parameters analyzed were loss of fresh mass, total solublesolids (TSS), total acidity (TA), TSS/TA ratio, ascorbic acid amount, and color (L*, C and ho). Increasing amountsof TSS were observed in all treatments except for organic strawberries at 11ºC. Acidity (% of citric acid) wereinitially 0.84% for organic strawberries and 0.70% for fruits from conventional crop systems. On the 15th day ofstorage, contents were 1.03% (organic strawberries at 1oC), 0.78% (conventional crop strawberries at 1ºC),0.97% (organic strawberries at 11ºC) and 0.76% (conventional crop strawberries at 11ºC). Greater amounts ofascorbic acid were observed in organic strawberries from the 1st to the 15th day of storage. Luminosity values(L*), in general, decreased during storage. Regardless of the crop system adopted (organic or conventional),strawberries showed a maximum shelf life of 6 days, with losses of fresh mass above 10% after that. 2006 artículo científico 1665-0204 https://www.redalyc.org/articulo.oa?id=81380105 en http://www.redalyc.org/revista.oa?id=813 Revista Iberoamericana de Tecnología Postcosecha application/pdf Asociación Iberoamericana de Tecnología Postcosecha, S.C.
