Strawberries have to be harvested when 75 percent of the fruit surface turns red and the berry is still firm. The strawberry fruit perishes easily and deteriorates within two to three days of harvesting at natural environmental conditions. The temperature is very important for the duration of berry life. Strawberries soften very quickly and become moldy as temperatures rise. So, to keep them longer, fruits must be picked at sunrise, transported to the processing place as soon as possible, and maintained in the shade in a cool place until processing.
