However, there’s actual science behind why these two popular vegetables shouldn’t be stored in close proximity.
Ethylene Gas Emission
Did you know that both potatoes and onions release ethylene gas?
This colorless and odorless gas is a natural plant hormone that aids in the ripening process.
While ethylene is beneficial for some fruits, when it comes to potatoes and onions, it can cause unwanted effects.
- Potatoes: Potatoes emit ethylene gas, which accelerates sprouting. Storing them alongside onions can lead to premature sprouting, reducing the potato’s shelf life and overall quality.
- Onions: Onions also release ethylene gas, which can cause potatoes to spoil more quickly. The gas emitted by onions can promote the sprouting of potatoes and even make them go bad faster.
Moisture and Humidity Levels
Another important factor to consider when storing potatoes and onions is the moisture and humidity levels in the storage area.
Both vegetables require specific conditions to maintain freshness and prevent rotting.
- Potatoes: Potatoes thrive in a cool, dark, and well-ventilated environment with low humidity. Storing them in a humid environment, such as alongside onions, can promote the growth of mold and bacteria, leading to spoilage.
- Onions: On the other hand, onions prefer a dry and well-ventilated storage space. Storing them in close proximity to potatoes, which require different conditions, can increase the overall moisture level, potentially causing both vegetables to spoil faster.
Physical Interactions
Apart from gas emissions and moisture levels, the physical interaction between potatoes and onions can also impact their storage quality.
- Sprouting: As mentioned earlier, potatoes are prone to sprouting due to ethylene exposure. Storing them near onions, which emit ethylene gas, can accelerate this process, resulting in sprouted and unusable potatoes.
- Flavor Transfer: Additionally, storing potatoes and onions together can lead to the transfer of flavors between the two vegetables. Onions have a strong aroma that can permeate potatoes, affecting their taste and causing an undesirable flavor combination.
while it may seem convenient to store potatoes and onions together, it’s best to follow the science-backed recommendations to ensure the longevity and quality of both vegetables.
By understanding the impact of ethylene gas emissions, moisture levels, and physical interactions, you can make informed decisions about how to store these pantry staples effectively.
Tips for Properly Storing Potatoes and Onions Separately
When it comes to storing potatoes and onions, many people wonder if it’s safe to keep them together.
Let’s delve into some tips for properly storing these two kitchen staples separately to ensure they stay fresh longer and maintain their quality.
Why Store Potatoes and Onions Separately?
Potatoes and onions may seem like a perfect pair in recipes, but when it comes to storage, they fare better on their own.
Here’s why:
Different Storage Requirements: Potatoes and onions have different storage requirements due to their unique characteristics. Potatoes prefer a cool, dark, and well-ventilated environment, while onions need a dry, well-ventilated space with some airflow. Storing them together can lead to premature spoiling.
