Artifical sweetener which is stable under cold conditions only is

Options

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

Explanation

To solve the question regarding which artificial sweetener is stable under cold conditions only, we can follow these steps:

### Step 1: Understand the Question
We need to identify an artificial sweetener that is specifically stable at low temperatures but decomposes when heated.

### Step 2: Analyze the Options
Let's look at the provided options:
- **A. Saccharin**
- **B. Sucralose**
- **C. Aspartame**
- **D. Elytane**

### Step 3: Review Each Option
- **Saccharin**: This sweetener is known to be stable at high temperatures and is about 300 times sweeter than sugar.
- **Sucralose**: This is another heat-stable sweetener, approximately 600 times sweeter than sugar.
- **Aspartame**: This sweetener is composed of aspartic acid, phenylalanine, and methanol. It is known to be about 180 to 200 times sweeter than sugar but decomposes when heated, making it suitable for cold conditions only.
- **Elytane**: This is also a sweetener, but specific details about its thermal stability are less commonly known.

### Step 4: Identify the Correct Answer
From the analysis, **Aspartame** is the only sweetener that is stable under cold conditions and decomposes when heated. Thus, the correct answer is **Option C: Aspartame**.

### Step 5: Conclusion
The artificial sweetener that is stable under cold conditions only is **Aspartame**.
