Understanding Lemon Spoilage: What Makes Lemons Go Bad?

Before we delve into preservation techniques, it’s crucial to understand why lemons spoil in the first place. Several factors contribute to their decline, including:

Moisture Loss: Lemons, like all fruits, contain a significant amount of water. As they sit at room temperature, they gradually lose moisture, leading to a shriveled, hard, and less juicy fruit.
Mold Growth: Mold thrives in humid environments. Lemons, especially if bruised or damaged, are susceptible to mold growth, rendering them inedible.
Oxidation: Exposure to air causes oxidation, which can degrade the lemon’s flavor and color over time.
Ethylene Gas: While lemons don’t produce much ethylene themselves, they are susceptible to damage from it. Keep lemons away from other fruit that produce more ethylene to keep them fresh longer.

By understanding these factors, we can implement storage methods that counteract them, extending the life of your lemons considerably.
