What happens when lemon juice goes bad?

1. Appearance: The clear and vibrant yellow color of fresh lemon juice may start to turn cloudy or opaque. This change in appearance is due to the breakdown of compounds in the juice.

2. Smell: Fresh lemon juice has a distinct citrusy aroma. As it goes bad, the smell may become sour, musty, or even slightly fermented.

3. Taste: Fresh lemon juice has a sharp and acidic taste. When it goes bad, the taste may become flat, bland, or develop an off-flavor. The acidity of the juice may also diminish over time.

4. Texture: The texture of fresh lemon juice is smooth and liquid. As it goes bad, the juice may start to develop a grainy or pulpy texture due to the breakdown of its cellular structure.

5. Mold Growth: In some cases, visible mold or yeast may start to grow on the surface of the lemon juice. This is a clear indication that the juice has spoiled and should not be consumed.

It's important to note that the rate at which lemon juice goes bad depends on several factors, such as storage conditions, temperature, and exposure to oxygen. Refrigerating lemon juice can help extend its shelf life, while exposure to heat, light, or air can accelerate its spoilage.
