Does storing watermelons and cucumber in the fridge result in flavor loss?

Question

I read that storing watermelons and cucumber in the fridge results in flavor loss. Is the flavor maintained for 1-3 days in the fridge, and only lost after this time? Or is it better never to put these items in the fridge?

Answer

The primary reason not to store watermelon and cucumber in the fridge is that they are sensitive to fridge temperatures. In addition, watermelon is sensitive to ethylene gas which is naturally produced by many fruit and can accumulate in the fridge. The reaction to low temperatures includes effects on flavor, texture and the rate of deterioration (faster). Cucumbers will see minimal effect of low temperatures for up to 3 days if used upon removal from the fridge. Ethylene causes mealy texture and loss of flavor in watermelon.
