Why is the sweetener shown used only in cold foods and soft drinks, not in baking?

AIt is insoluble in water
BIt is too bitter when heated
CIt is unstable at cooking temperature
DIt forms calcium salts

Answer: C

The compound shown is aspartame. At cooking or baking temperature it decomposes (the peptide and ester bonds hydrolyse), so it loses its sweetness, which restricts it to cold foods and drinks.
