| Abstract:
Fruits of the strawberry cultivars Fern, Brighton and Selva were used in tests conducted during 1991 to evaluate their postharvest quality during cold storage and shelf - life. The fruits were stored at 3, 6 or 20 °C for various durations of storage for 0, 2, 4, 6 and 8 days covered with plastic film or uncovered. Fruit firmness, weight, colour (L*, a*, b*) and titratable acidity decreased during storage, pH, soluble solids and a*/b* ratio increased, while ascorbic acid content did not change significantly. Storage for 4 days at 3 °C did not affect fruit quality significantly, while storage for 6 days resulted in softening of the fruit and increased the fruit weight loss. After 8 days in storage, fruits were unmarketable. Wrapping the fruits with plastic film reduced significantly the weight loss at either temperature 3 or 6 °C, compared to the uncovered fruits. Temperature affected significantly the weight loss of the uncovered fruits at any temperature tested. | |
