What produce needs to be wrapped before refrigerating?

Food scientist Dr. Clair Hicks offers this explanation: “Fresh fruit and vegetables have different respiration rates.  For example, asparagus and broccoli have high respiration rates, which requires that they be refrigerated (that slows the respiration rate) but that they be stored in breathable packaging.  Apples and citrus fruits have low respiration rates, and apples, cucumbers, and tomatoes are waxed to further slow respiration, so only refrigeration is required to enhance shelf life. Many loose vegetables do quite well in the vegetable drawer of the refrigerator.  

Onions and potatoes are commonly bagged in breathable packaging and should be stored in cool, dark places.” (For onions and potatoes: If you have a place in your home that’s around 55ºFº, that’s perfect. If not, the fridge is okay.  Darkness is important to prevent sprouting.
