Mushrooms' Intriguing Food Preparation Process

Mushrooms are a unique type of fungus that belongs to a kingdom separate from plants and animals. Unlike plants, mushrooms do not rely on photosynthesis to create their food. Instead, they obtain their nutrients from external sources, including dead and decaying plants, small insects that wander too close, and even the water we provide for them.

Dead and decaying plants

Mushrooms are saprophytes, meaning they are decomposers that feed on dead and decaying plants and animals. They break down organic matter to obtain nutrients, as they do not contain chlorophyll and therefore cannot produce their own food through photosynthesis.

Saprophytic mushrooms, such as oyster and shiitake mushrooms, grow on dead and decaying plants, particularly trees. As ancient trees, such as oak, begin to decay, mushrooms fruit out of the wood, breaking it down for food. This process involves a network of mycelium, a type of fungus, that grows throughout the wood, soil, and other decaying matter, helping mushrooms grow and obtain nutrients.

Primary decomposer mushrooms, such as oyster and shiitake, are the first to grow on decaying matter. They grow quickly and break down larger molecules into food. Secondary decomposers then continue the decomposition process, breaking down plant and animal tissues further. Tertiary saprophytic mushrooms grow when there is less compostable material left.

This decomposition process is essential for ecosystems and agriculture. By recycling nutrients from dead organic matter, saprophytic mushrooms ensure that the soil remains fertile and can support the growth of new plants. Without this process, the soil would eventually lose its nutrients, disrupting the food chain.

While most saprophytic mushrooms grow on dead or decaying plants, some, like Chestnut and Lion's Mane mushrooms, can also grow on live trees, exhibiting both saprophytic and parasitic characteristics.

Photosynthesis

Mushrooms are part of the fungi kingdom, distinct from plants and animals. Unlike plants, they do not contain chlorophyll and therefore cannot directly prepare their own food through photosynthesis. Instead, they rely on external sources of energy and carbon in the form of complex organic compounds.

Fungi, including mushrooms, obtain their nutrients from a variety of sources. One of these sources is dead and decaying plants, which they break down and utilise for growth and energy. Additionally, they may feed on small insects that come near them, as well as water.

While mushrooms do not photosynthesise, they can still benefit from light exposure. Mushrooms exposed to ultraviolet light, for example, are a good source of vitamin D. This form of light exposure can enhance the nutritional profile of mushrooms, making them an even more valuable component of a healthy diet.

It is important to note that mushrooms are heterotrophic organisms, meaning they depend on other sources of organic compounds for their energy needs. This is in contrast to plants, which are typically autotrophic, capable of self-generating nutrients through photosynthesis.

In summary, while mushrooms do not directly prepare their food through photosynthesis, they play an important role in breaking down organic matter and obtaining nutrients from a variety of sources, including dead plants, insects, and water. Their ability to utilise external sources of energy contributes to their growth and survival within their unique ecological niche.

Eating small insects

Mushrooms are a food source for many different organisms, including insects. Insects that eat mushrooms include the sciarid fly, cecid fly, phorid fly, springtails, and fungus gnats. These insects can be considered pests to mushroom growers, as they can destroy crops and leave mushrooms inedible.

To prevent insects from eating mushrooms, growers can use insecticides or insecticidal soap. For example, Safer® Brand Neem Oil Insecticide with Neem Oil Concentrate kills many soft- and hard-bodied insects and can be sprayed on the walls and floors of the mushroom house. Safer® Brand Insecticidal Soap & Pyrethrin attacks insects' nervous systems while weakening their outer shells and can be sprayed directly on insects.

When foraging for mushrooms, it is important to check for insects and larvae. Springtails, fungus gnat larvae, and slugs/snails are common inhabitants of wild mushrooms. To remove bugs and larvae from foraged mushrooms, you can trim any obviously bitten or discolored areas and slice across the base of the stem to check for bug holes. Soaking mushrooms in saltwater can also help to remove bugs, but it may affect the texture and make the mushrooms too salty.

While most insects that eat mushrooms are considered pests, some species of ants have been found to primarily eat mushrooms. The Euprenolepis procera ant from the rainforests of Southeast Asia has a diet consisting almost entirely of mushrooms.

Water

Mushrooms are a part of the Fungi kingdom and differ from plants and animals in the way they obtain their nutrients. Fungi are heterotrophic in nature and use complex organic compounds as sources of energy and carbon, instead of photosynthesis.

Mushrooms obtain their food from dead and decaying plants, eating small insects that come near them, and the water we pour near them. Fungi need water for all stages of life and consist of about 90% water. They degrade organic matter by secreting enzymes, which need water to break down the substrate. When the substrate is too dry, fungi transport water from moist areas to arid areas by hydraulic redistribution. Water flow is determined by the water potential of the substrate and of fungal tissues.

When it comes to cooking mushrooms, there are differing opinions on whether or not to use water. Some sources claim that mushrooms are like little sponges and will get waterlogged if washed or soaked. Instead, it is recommended to clean them with a damp paper towel or brush. However, others argue that water is not the enemy and can be used to extract the most flavor from mushrooms. This can be done by washing and boiling the mushrooms in water before reducing the remaining liquid in the pan.

Additionally, when cooking mushrooms in a pan, they will release their abundant water content. By cooking them over medium-high or high heat, the water will evaporate, and the mushrooms will develop a nice brown color without absorbing oil. This technique is known as water sautéing.

No chlorophyll

Mushrooms are part of the fungi kingdom, which also includes mould and yeast. Fungi are not plants, and their cell walls are made of chitin, a substance not found in plants. The bodies of multicellular fungi, like mushrooms, are made of cells that band together in rows that resemble tree branches. Each branched structure is called a hypha, and several hyphae mesh together to form the mycelium, which constitutes the fungal body.

Mushrooms are heterotrophs, meaning they feed on decaying matter. They do not contain chlorophyll, the substance in plants that absorbs sunlight and converts it into energy through photosynthesis. Instead, mushrooms obtain their energy by breaking down organic matter. This process of obtaining energy from other organisms is known as chemosynthesis.

Fungi play an important role in ecosystems by breaking down dead plants and animals and returning nutrients to the soil. They are also involved in mutualistic relationships with the roots of certain plants, helping the plants absorb water and minerals from the soil while obtaining carbohydrates from the plants in return.

While mushrooms do not require chlorophyll to survive, they still contain important nutrients, including vitamins, minerals, and antioxidants. For example, cremini mushrooms are an excellent source of zinc, which is essential for immune health and optimal growth in infants and children. Mushrooms are also a good source of potassium, which can help reduce blood pressure and lessen the negative impact of sodium on the body.
