Drying Mushrooms: Retaining Potency For Maximum Benefits

how do you dry mushrooms without losing potency

Drying mushrooms is a great way to preserve them for long-term storage. Properly dried mushrooms can be stored for months without losing their flavour or potency. There are several methods for drying mushrooms, including using a dehydrator, an oven, or air drying. While the jury is still out on whether cutting or tearing mushrooms before drying affects their potency, it is generally recommended to dry mushrooms thoroughly to maintain their potency.

Pre-drying: wipe mushrooms with a damp cloth, then air-dry or use a dehydrator

Before drying mushrooms, it is important to clean them. Use a brush or a dry paper towel to wipe away any dirt. If there are spots of dirt that won't come off, use a damp cloth or paper towel to scrub them off. Just be sure to wipe the same spot with a dry cloth or paper towel to absorb any leftover moisture.

After cleaning, you can begin the pre-drying process. Pre-drying is a method of removing excess water from mushrooms before thoroughly drying them out. To pre-dry mushrooms, you can either air-dry them or use a dehydrator.

Air-drying is the oldest form of food preservation, dating back at least 12,000 years. It is the most accessible way to dry mushrooms, as it doesn't require any equipment. However, it only works if the relative humidity of the environment is below a certain threshold, around 55% RH. If you're not sure how humid your room is, use a hygrometer to measure the humidity.

To air-dry mushrooms, place them on a screen door or mesh onion bags in a well-ventilated area. To speed up the process, you can place a fan between the mushrooms and the source of fresh air. It typically takes 2-3 days for mushrooms to fully dehydrate using this method.

Using a food dehydrator is another effective way to pre-dry mushrooms. Dehydrators efficiently remove moisture from food by gently heating it and circulating the air. Most dehydrators have a temperature range of around 35°C to 70°C. When using a dehydrator, it's important to set it to a low temperature and check on your mushrooms frequently. Depending on the model, your mushrooms should be ready in about an hour.

Whether you choose to air-dry or use a dehydrator, the goal of pre-drying is to ensure that your mushrooms are completely dry before storing them. A properly dehydrated mushroom should snap apart easily and be free of any moisture, which can lead to mould or bacteria growth.

Drying: use an oven, dehydrator, or sunlight

Drying mushrooms is a great way to preserve them for long-term storage. Here are some methods you can use to dry mushrooms without losing potency:

Oven

If you want to dry mushrooms in an oven, preheat the oven to 150°Fahrenheit (65°Celsius). Place the mushrooms on a baking sheet and put them in the oven for about an hour. Then, take them out and flip them over to dry evenly. Blot any moisture that may have formed on the surface with a paper towel or dry cloth. Put the mushrooms back in the oven for another hour or until they are completely dry. Check if there is any moisture left and repeat the process if necessary. Once the mushrooms are dry, let them cool on the baking sheet. Do not put them in an airtight container until they are completely cool, as the heat may cause condensation.

Dehydrator

A food dehydrator is another effective way to dry mushrooms. Dehydrators work by gently heating the mushrooms, circulating air to encourage evaporation, and pushing moist air out through vents. Depending on the model, you can set the temperature of a dehydrator anywhere between 35°C and 70°C. A higher temperature will dry the mushrooms faster. However, keep in mind that you will need to monitor the mushrooms more closely at higher temperatures. When using a dehydrator, it is recommended to cut the mushrooms into smaller pieces to speed up the drying process.

Sunlight

Drying mushrooms in the sun is a free and easy method that does not require any electricity. However, it is important to note that this method only works in sunny and non-humid environments. Choose a spot that gets plenty of sunlight, such as a room with large windows, a flat roof, or a windowsill. Ensure the area is protected from moisture, insects, and animals, and has good airflow. The drying process will take longer than with an oven or dehydrator, but sunlight is the best method for preserving the flavour and potency of mushrooms.

Regardless of the drying method you choose, it is important to clean the mushrooms before drying them and to make sure they are completely dry before storing them. Mushrooms should be cracker dry, meaning they snap easily and break apart. Store dried mushrooms in airtight containers in a cool, dark place to maximize their shelf life and potency.

Storage: store in airtight containers in a cool, dark place

Proper storage is essential to maintaining the potency and safety of psilocybin-containing products. To store dried mushrooms, place them in airtight containers in a cool, dark place.

Airtight containers are crucial for keeping out oxygen, which causes mushrooms to degrade quickly. Oxygen exposure can lead to oxidation and the degradation of psilocybin. Use containers that allow you to remove excess air, or employ vacuum-sealing techniques to minimise oxygen exposure.

Ideal storage containers for dried mushrooms include airtight glass jars with tight seals, vacuum-sealed plastic bags, or mason jars. Avoid plastic bags, as they can trap moisture, leading to mouldy mushrooms.

When selecting a storage location, choose a cool, dark place such as a cabinet, pantry, or room with moderate temperatures, ideally between 60-70°F. Avoid exposing the mushrooms to sunlight and heat, as this can degrade the psilocybin compound and reduce potency. Keep them away from direct sunlight and heat sources.

Additionally, maintain a dry environment during storage to prevent mould growth. Desiccants like silica gel packs can be placed inside containers to absorb any residual moisture and ensure mushrooms remain dry.

Regularly inspect your stored mushrooms for any signs of mould or degradation. If contamination is detected, discard the affected mushrooms and do not mix them with other containers to prevent the spread.

Rehydrating: soak in water for 4 hours or cover with hot water for 30 minutes

When you're ready to cook your dried mushrooms, you'll need to rehydrate them. There are two effective ways to do this. The first method involves submerging the mushrooms in a bowl of water for four hours. The second method is faster and involves covering the mushrooms with water just off the boil, placing a plate over the bowl to trap the steam, and letting them sit for 30 minutes. After this, drain the mushrooms over another bowl to reserve the liquid for cooking, and place the mushrooms on a towel to dry briefly.

While reconstituted mushrooms may not be quite as good as fresh ones, they are still a treat. You can use them in soups, risottos, pasta dishes, and pretty much every delicious recipe you can think of.

Loss of potency: slicing or cutting mushrooms may reduce potency

Drying mushrooms is a great way to preserve them for long-term storage. However, there are some considerations when it comes to maintaining their potency during the drying process. One common concern is whether slicing or cutting mushrooms before drying impacts their potency.

When it comes to drying mushrooms, the general consensus is that they should be dried thoroughly to prevent spoilage and extend their shelf life. Proper drying ensures that mushrooms retain their flavour and potency over time. While slicing or cutting mushrooms increases their surface area and facilitates faster drying, there is conflicting evidence regarding its impact on potency.

Some growers claim that slicing or cutting mushrooms does not affect their psychoactive effects. They argue that this technique helps remove excess water, which is crucial for effective drying and long-term storage. On the other hand, some cultivators suggest that cutting mushrooms ruptures the cell walls of the mycelium, leading to excessive bluing and potential loss of potency. They propose that tearing mushrooms instead of cutting them may keep the cell walls intact, preserving potency to a greater extent.

Ultimately, the decision to slice or cut mushrooms depends on personal preference and the specific drying method being employed. While there may be some potential loss of potency due to cutting, the more critical factor is ensuring thorough drying to prevent spoilage and maintain flavour and potency as much as possible.

To effectively dry mushrooms without losing potency, it is recommended to use a food dehydrator, which removes moisture by gently heating and circulating air while venting moisture. Alternatively, air drying in a well-ventilated, non-humid environment is another option, although it may be inconsistent and take longer. When using an oven, it is crucial to use low temperatures to avoid destroying beneficial compounds and to prevent rapid drying, which can impact potency.

Frequently asked questions

Mushrooms should be dried in a cool, dry, well-ventilated environment. A food dehydrator is the most efficient method, but alternatives include placing the mushrooms on a wire rack and pointing a fan at them, or using an oven on a low setting with the door ajar.

Mushrooms should be "cracker dry", meaning they snap easily and break apart. If they still bend, they are not dry enough and may develop mould.

The jury is out on this one. Some growers claim that cutting mushrooms makes no difference to their potency, while others state that it ruptures the cell walls of the mycelium, leading to a potential loss of potency. Ultimately, it is a matter of personal preference.
