Why is use of aspartame limited to cold foods and drinks ?

Options

A. it is unstable to heat and decomposes at cooking temperature
B. it is 500 times sweeter than cane sugar
C. it becomes bitter at cooking temperature
D. it reacts with the food at cooking temperature .

Answer

**Step-by-Step Solution:**

1. **Understanding Aspartame**: Aspartame is an artificial sweetener commonly used in various food products and beverages as a sugar substitute. It is known for its high sweetness level, being approximately 200 times sweeter than sucrose (table sugar).

2. **Stability of Aspartame**: One of the critical factors to consider when using any food additive is its stability under different conditions, particularly temperature. Aspartame's stability is affected by heat.

3. **Effect of Heat on Aspartame**: When exposed to high temperatures, such as those encountered during cooking, aspartame can decompose. This decomposition leads to a loss of sweetness and the formation of potentially undesirable by-products.

4. **Conclusion on Usage**: Due to its instability at cooking temperatures, aspartame is recommended for use only in cold foods and beverages. This ensures that it retains its sweetness and does not break down into less desirable compounds.

5. **Final Answer**: Therefore, the use of aspartame is limited to cold foods and drinks because it is unstable to heat and decomposes at cooking temperatures.
