They won't be as aromatic and savory because cold hinders the conversion of the vegetable's linolenic acid to Z-3 hexenel, the compound that accounts for much of the desirable ripe-tomato scent and taste. Cold also reduces the volatility of molecules and therefore the number of Z-3 hexenel molecules that will reach your olfactory receptors. Another way to foster Z-3 hexenel development is never to place store-bought tomatoes in the refrigerator when you return home from the market (as most shoppers do). Instead, allow the tomatoes to ripen at room temperature for several days. They will be considerably more delicious.
