Answer

(3) aspartame

Solution

As per NCERT, aspartame is the most successful and widely used artificial sweetener; it is roughly 100 times as sweet as cane sugar. It is the methyl ester of a dipeptide formed from aspartic acid and phenylalanine.

⇒ Use of aspartame is limited to cold foods and soft drinks because it is unstable at cooking temperature.

∴ Aspartame is stable under cold conditions only.
