Mushrooms are a versatile ingredient used in various dishes, from salads to soups. However, their high water content makes them susceptible to spoilage. Proper storage is critical to preserving their freshness and preventing food poisoning, which can cause nausea, vomiting, and diarrhea. Fresh mushrooms typically last 3-7 days in the refrigerator, while cooked mushrooms can be stored for up to 4 days. To extend their shelf life, some people opt for drying mushrooms, which can last for months or even years when stored in airtight containers in cool, dry places. Additionally, magic mushrooms and mushroom capsules have a short shelf life and are susceptible to contamination and spoilage, requiring proper storage and handling to maintain potency and safety.

What You'll Learn
How to store mushrooms
Mushrooms are a versatile ingredient, but they are also delicate and perishable. To store mushrooms, you should avoid trapping moisture, which causes discolouration, mould and slime. Therefore, it is best to avoid storing mushrooms in their original plastic packaging or in plastic containers.
The best way to store fresh mushrooms is to place them in a brown paper bag and loosely fold over the top. This allows the mushrooms to breathe, and the paper absorbs moisture to prevent mould. You can also wrap mushrooms in a paper towel and place them in a bowl in the refrigerator.
Mushrooms should be stored in the refrigerator, ideally on a shelf rather than in a produce drawer, at a temperature below 40 °F (4 °C). They should be kept away from strong-smelling food, as mushrooms absorb odours. Whole mushrooms should be used within a week of purchase, and sliced mushrooms within 4 to 7 days.
If you are not planning to eat your mushrooms within a few days, you can also dry them. This involves placing mushrooms in a mesh container with good airflow for about a week. Once they are dry, store them in an airtight glass jar or a resealable plastic bag in a dark, dry place. Dried mushrooms have an indefinite shelf life and an intense umami flavour.

How to identify spoiled mushrooms
Mushrooms are a versatile ingredient that can elevate any dish with their unique flavours and textures. However, like any other food, they can spoil if not stored or handled correctly. Using spoiled mushrooms in cooking can cause food poisoning, leading to severe illness or even becoming life-threatening. Therefore, it is crucial to identify spoiled mushrooms.
Firstly, visually inspect the mushrooms for any signs of decay, such as discolouration, wrinkles, spots, or a sticky and slimy texture. Fresh mushrooms should have a firm, plump appearance and a consistent colour. If you spot these visual cues, it means the mushrooms are no longer fresh and should be discarded.
Secondly, use your sense of smell to assess the mushrooms. Fresh mushrooms should have a mild, earthy, and slightly sweet aroma. If they have a strong, pungent, or unpleasant smell, it indicates spoilage. A strong ammonia-like smell suggests that harmful bacteria have taken hold, and the mushrooms should be thrown away.
Thirdly, touch the mushrooms to check their texture. Fresh mushrooms should feel firm, springy, dry, crisp, and light. If they feel soft, soggy, spongy, floppy, sticky, or mushy, they have likely begun to decompose and are no longer safe to eat.
Lastly, consider the storage conditions of the mushrooms. Whole, raw mushrooms stored in a refrigerator will typically last four to seven days, while sliced mushrooms will only last two to three days. Proper storage is essential to prevent moisture buildup, which can lead to spoilage. Avoid plastic bags and sealed containers, and instead use breathable containers, such as paper bags or paper towels, to keep moisture away from the mushrooms.
In summary, spoiled mushrooms will typically exhibit visual, olfactory, and textural changes. They may appear discoloured, slimy, or mouldy, emit a foul odour, and feel soft or sticky. By identifying these signs of spoilage, you can ensure that you only consume fresh and safe mushrooms, maintaining both your health and the quality of your culinary creations.

The shelf life of fresh mushrooms
Fresh mushrooms typically last between 3 and 7 days in the refrigerator. However, it's important to note that different varieties of mushrooms have different shelf lives, and the conditions of your fridge may also impact how long they last.
When buying fresh mushrooms, choose whole mushrooms with intact caps and stalks. Avoid any that are broken or bruised, as these have a shorter shelf life. Before placing them in the refrigerator, remove the mushrooms from their original container and place them in a paper bag. Paper bags allow the mushrooms to breathe and prevent excess moisture from building up, which can cause spoilage. Make sure the mushrooms are free of excess dirt or moisture, as damp mushrooms spoil faster. Keep them on a shelf in your refrigerator, as the standard drawer settings may not be cold enough. The ideal temperature range is between 35-40°F (1.5-4°C).
Check your mushrooms daily for signs of spoilage. Discoloration, a slimy texture, or an off smell are all indications that mushrooms have gone bad. If you notice wrinkles, this means they are drying out, and you should consider eating them immediately or adding them to a liquid-based dish to rehydrate them.
If you don't plan on using your mushrooms within a few days, you can extend their shelf life by drying them and storing them in an airtight container in a cool, dry, and dark place. Properly dried mushrooms can last for months or even years.

The shelf life of dried mushrooms
Dried mushrooms have a much longer shelf life than fresh mushrooms, which can spoil within a week. When stored properly, dried mushrooms can last indefinitely. They are non-perishable from a microbiological standpoint and do not have a true expiration date.
Dried mushrooms are sealed in airtight packaging to maintain their structural, nutritional, and organoleptic properties. After opening, they should be stored in an airtight container in a cool, dark, dry place. Exposure to sunlight, heat, or damp environments should be avoided as this can cause natural decay. The best option for long-term storage is in the freezer.
Dried mushrooms can be stored for years without losing quality, although they may lose some flavour over time. They are also low in calories and rich in valuable nutrients, making them a versatile ingredient in a variety of dishes.
It is important to check for signs of spoilage, such as mould, spots, or the presence of pests. If there are no visible signs of deterioration, dried mushrooms can be consumed after their best-before date without any health risks. However, Italian law states that the date of minimum durability for dried mushrooms cannot exceed 12 months from the packaging date.

The shelf life of mushroom capsules
Mushroom capsules are a convenient way to consume mushrooms and benefit from their health advantages without cooking or preparing them. They typically have a shelf life of one to two years, depending on the type of mushroom and storage conditions.
To ensure the capsules' longevity, proper storage is critical. Keep them in a cool, dry place, away from direct sunlight and moisture. UV rays can break down the active compounds in the mushrooms, and moisture can cause mould or spoilage. Use airtight containers to minimise humidity and store them in opaque or dark-coloured containers to protect them from light.
The potency of mushroom capsules may also decline over time, so it is important to consume them within the recommended shelf life for the best experience. Check for changes in colour and texture as indicators of degradation. A decline in effectiveness can also signal expired capsules.
Fresh mushrooms have a much shorter shelf life than dried ones. They are best consumed within a week after harvest and should be stored in a paper bag in the refrigerator. If not refrigerated, they last only a few days. On the other hand, dried mushrooms can last for months or even years if properly stored in airtight containers in a cool, dark, and dry environment.
