A fruit is alive, and for it to ripen normally, many biochemical reactions must occur in a proper order. After pollination, proper nutrition, growing conditions, and certain plant hormones cause the fruit to develop and grow to proper size. During this time, fruits store energy in the form of starch and sugars, called photosynthates because they are the product of photosynthesis from the plant. Upon completing the growth phase, the fruit enters the ripening phase. The U.S. Department of Agriculture reported that, of all the fresh produce purchased by the average home, 25 percent is thrown away due to decay or becoming overripe. This article presents a scientific discussion describing the ripening process of various types of fruits, and provides consumers with tips for storing fruits at home in order to mazimize flavor and minimize spoilage.
