Everyone likes buying fresh, ripe tomatoes. However, you might not be getting what you paid for. Research showed that when you buy tomatoes at the store they are not as ripe as you think. Sugars and acids, known as volatiles, immediately degrades once it is picked from the vine. If you want a ripe tomato, you might as well pick it off the vine and eat it right away. If you don't think this is bad, keeping tomatoes in the refrigerator also erases genes that are responsible for flavor. Scientists at the University of Florida kept tomatoes in 41 degrees Fahrenheit. The results showed that the cold temperature made the tomato go into shock and it turned off genes that were responsible for flavor. Even when the tomato was kept in room temperature at 68 degrees Fahrenheit, the genes were still off. It is thus recommended to store your tomatoes at room temperature at all times and to consume within a week of purchasing.
