Lemons: The Age-Old Trick of Soaking Citrus Fruits in a Saline Solution


Renowned for their concentrated vitamin C and beneficial antioxidants, lemons are a citrus fruit worth keeping in your pantry. Whether crafting a refreshing juice or enhancing the flavor of drinks and dishes, lemons are a versatile ingredient. While store-bought lemon juice is an option, the advice of preparing it from freshly harvested, perfectly preserved citrus fruits is always wise. To prevent the formation of mold, a common concern with lemons, proper preservation is crucial.

Storing lemons in the refrigerator might not be the optimal solution, as the cold temperature can potentially dehydrate the fruit and cause the citrus peel to “dry out.” So, what is the ideal way to store an abundance of lemons? Let’s explore the best practices.

Understanding Lemon Mold Formation

Mold tends to develop on lemons due to various factors, including climatic conditions and the processes involved in harvesting and distribution. Injuries sustained during transport expose the citrus fruits to mold formation. Additionally, the acidic pH of lemons makes them more susceptible to fungal spores, which thrive in acidic environments. While green mold may affect lemons, it doesn’t render them toxic or harmful to touch or smell. How can we effectively preserve lemons to prevent the formation of blue or green mold? Let’s delve into the solutions.


Preserving Lemons: Keeping Mold at Bay

Preserving lemons naturally at home is possible without succumbing to fungal attacks and mold formation. A simple method can be followed to achieve this.

Upon acquiring a supply of lemons, slice them and place the citrus slices in a container filled with water and salt. After sealing the container, shaking it ensures the preservation of these citrus fruits for extended periods.

Another effective and natural method involves washing lemons and soaking them in a solution of baking soda and water. This process eliminates bacteria, counteracts mold formation, and, after thorough drying, prevents humidity from contributing to mold growth.


Once clean and dry, placing lemons in a sanitized, preferably airtight container acts as a preventive measure, hindering fungi contact with the peel and averting the development of green or blue mold. Alternatively, storing lemons in a paper bag at room temperature or in the refrigerator proves to be another effective remedy.
