Question

Artificial sweetener which is stable under cold conditions only is

• A. saccharine
• B. sucralose
• C. aspartame
• D. alitame

Answer 1

The Correct Option is C

The question revolves around identifying an artificial sweetener that remains stable under cold conditions. Let's examine each option:

1. Saccharine: This artificial sweetener is known for its long shelf-life and stability. However, it is generally stable across different temperatures, not specifically under cold conditions only.
2. Sucralose: As a chlorinated sugar, sucralose is known for its stability under heat, making it suitable for cooking and baking. It is not limited to stability under cold conditions.
3. Aspartame: Unlike other sweeteners, aspartame is sensitive to heat and tends to degrade when exposed to high temperatures. It retains its stability in cold conditions, which makes it suitable primarily for cold beverages and foods.
4. Alitame: This is another artificial sweetener with good thermal stability, meaning it maintains its sweetness even when exposed to heat.

Based on the above analysis, the artificial sweetener "aspartame" is the one that is stable under cold conditions only. It is less stable when exposed to heat due to its decomposition into phenylalanine, which may affect its sweetness and is a limitation for its use in hot products.

Conclusion: The correct answer is aspartame.
