Selection and Ca Select oranges that are firm and heavy, which is a
sign of juicy fruit. Cold weather causes fruit to develop a bright
orange color, so these oranges may be ripe and still have a greenish
tinge on the skin. Oranges found in the market are sanitized by a
washing process and treated with a thin coat of edible wax. Those
coming directly out of the grove may not have had this process. If
they have not been washed and waxed then you should not wash them until
ready to use. Washing removes the natural preservative on the skin and
will cause faster deterioration. The wax coating retards spoilage.
Oranges should be stored in the refrigerator 3-4 weeks between 50-60
degrees F. The juice of the navel orange is not desirable for
processing or freezing due to the bitterness caused by limonine.
