Mushrooms should be stored in the refrigerator
The refrigerator is the ideal location for storing mushrooms, but the exact spot you select can influence their longevity. It is best to avoid the crisper, as it tends to have high humidity, which is not suitable for mushrooms. The top of the fridge is another place to avoid, as it can be a few degrees higher than room temperature, accelerating spoilage.
To prevent moisture accumulation, which leads to discoloration, mould, and slime, mushrooms should be stored in a breathable container in the refrigerator. A paper bag is a great option, as it absorbs excess moisture and helps maintain freshness. If using a paper bag, it is recommended to include paper towels, as they can further help absorb moisture. Alternatively, mushrooms can be wrapped in a paper towel and placed in a bowl in the refrigerator.
It is important to avoid storing mushrooms in plastic containers or bags, as they trap moisture. If mushrooms are purchased in sealed plastic containers, it is recommended to remove them and store them in a paper bag or with a paper towel in a bowl. Additionally, sliced mushrooms should be stored in an airtight container in the refrigerator.

Use a breathable container
Mushrooms are a versatile staple in any kitchen, known for their meaty texture and umami flavour. However, their delicate and perishable nature means that proper storage is essential to preserve their quality and flavour. The refrigerator is the ideal location for storage, but the exact spot you select can influence their longevity.
One of the key considerations when storing mushrooms is moisture control. Mushrooms are composed of 80 to 90 percent water and have a porous texture, allowing them to easily soak up excess moisture. Plastic containers or bags without holes can trap moisture, leading to discoloration, mould, and slime. Therefore, it is crucial to use a breathable container for storage.
A recommended method for storing mushrooms is to use a paper bag. Paper bags, either brown or regular, can effectively absorb excess moisture, helping to keep the mushrooms fresh. They also allow for air circulation, preventing the buildup of moisture that can accelerate spoilage. Simply place the mushrooms in the paper bag and store them in the refrigerator. This method can extend the shelf life of mushrooms by several days.
Alternatively, if you prefer to use a container, opt for a mesh container with good airflow. Mesh containers provide ventilation while still protecting the mushrooms from external elements. This option is particularly useful if you want to store mushrooms in larger quantities or for longer periods.
It is worth noting that sliced mushrooms require a different storage approach. Once cut, mushrooms are more susceptible to drying out. Therefore, sliced mushrooms should be stored in an airtight container in the refrigerator. This will help retain their moisture and keep them fresh for a few days.
By utilising breathable containers, such as paper bags or mesh containers, you can effectively maintain the freshness and quality of mushrooms while taking advantage of their extended shelf life.

Paper bags are ideal
Mushrooms are a versatile staple in any kitchen, known for their meaty texture and umami flavour. However, their delicate and perishable nature means that proper storage is essential to preserve their quality and flavour.
If you don't have access to a paper bag, you can wrap the mushrooms in a paper towel and place them in a bowl in the refrigerator. Like the bag, the paper towel will absorb moisture, helping the mushrooms stay fresh. It is important to avoid using plastic containers or bags, as they can trap moisture and speed up spoilage.
Storing mushrooms in a paper bag can extend their shelf life, with some sources claiming they can last up to 10 days when stored this way. However, it is recommended to use whole mushrooms within a week of purchase, regardless of the storage method.
Additionally, if you are looking for a long-term storage option, you can consider drying your mushrooms. This method better preserves the quality of the fungi while indefinitely extending their shelf life. Dried mushrooms have an intense umami flavour and can be reconstituted in soups, stews, sauces, or stir-fries.

Avoid plastic containers
When it comes to storing mushrooms, it is generally recommended to avoid using plastic containers, especially sealed ones without holes. Mushrooms have a porous texture and absorb water easily, so they need to be stored in a way that promotes breathability and prevents moisture buildup. Plastic containers can trap moisture, accelerating spoilage and leading to slime development.
Instead of plastic, it is preferable to use breathable materials like paper bags or paper towels. Paper bags are an excellent option for storing mushrooms in the refrigerator, helping to maintain freshness for 4-5 days. Paper towels can also be used by wrapping the mushrooms and placing them in a bowl in the refrigerator. This method helps to absorb excess moisture and keeps the mushrooms fresh.
For those who wish to grow their own mushrooms, there is a growing awareness of the environmental impact of single-use plastic containers and a desire to move towards more sustainable alternatives. Biodegradable plastic and reusable containers are being explored, although cost and flexibility remain considerations. Glass containers, for instance, are often excluded due to their weight, fragility, and lack of flexibility, especially when removing colonized blocks.
However, some mushroom growers and enthusiasts are committed to reducing their plastic usage. They opt for reusable containers like buckets, jars, and modified storage tubs, which can be made from materials other than plastic. These options not only benefit the environment but also offer cost savings over time.

Sliced mushrooms should be stored in an airtight container
It is important to note that the refrigerator is the ideal location for storing mushrooms, but the exact spot you select can influence their longevity. It is recommended to avoid placing mushrooms near strong-smelling food, as they will absorb those odors. Additionally, it is best to avoid washing mushrooms before storing them, as this will shorten their shelf life.
To store mushrooms in the refrigerator, you can use a brown paper bag or paper towels. Simply put whole, unwashed mushrooms in a brown paper bag and fold the top over to seal it. This will help to keep the moisture at bay and prevent the mushrooms from becoming slimy. Another option is to wrap the mushrooms in a paper towel and place them in a bowl in the refrigerator. The paper towel will absorb moisture, helping the mushrooms stay fresh.
If you are storing sliced mushrooms, it is best to use an airtight container. This will help to prevent the mushrooms from drying out and extend their shelf life. However, it is important to note that some sources suggest that storing mushrooms in an airtight container can cause them to decompose faster. This may be due to the lack of airflow, which can cause condensation and spoilage.
Overall, the best practice for storing sliced mushrooms is to use an airtight container in the refrigerator. This will help to maintain their freshness and extend their shelf life for up to three days.
