Fungi are not only delicious, but also nutritious and environmentally friendly. They can be grown on various substrates, such as oats, and produce high-quality protein and other bioactive compounds.
Fungi as a source of protein and health benefits
Protein is an essential macronutrient that plays a vital role in many biological processes, such as muscle growth, immune function, and enzyme activity.
However, not all protein sources are equal in terms of quality, digestibility, and environmental impact.
Animal products, such as meat, eggs, and dairy, are often considered as high-quality protein sources, but they also come with drawbacks, such as high greenhouse gas emissions, land use, water consumption, and animal welfare issues.
Fungi, on the other hand, can provide a more sustainable and ethical alternative to animal products. They are classified as eukaryotic microorganisms that belong to neither plants nor animals.
They include mushrooms, molds, yeasts, and truffles.
Some fungi are edible and can be cultivated on various substrates, such as grains, legumes, or agricultural residues.
These fungi are called filamentous fungi, because they form long thread-like structures called hyphae that grow into a mass called mycelium.
Filamentous fungi can produce high-quality protein that is comparable to animal protein in terms of amino acid composition and digestibility.
For example, Aspergillus oryzae, a fungus that is widely used in Asian cuisine and fermentation processes, can produce up to 40% protein on dry weight basis when grown on oat flour.
Moreover, filamentous fungi can also synthesize bioactive compounds that have health benefits for humans.
One of these compounds is L-carnitine, which is involved in energy metabolism and can improve cardiovascular health.
Aspergillus oryzae has been shown to produce more L-carnitine than other fungal species when grown on oat flour.

Fungi as a basis for innovative food products
Fungi not only offer nutritional and health benefits but also culinary and sensory appeal. It has a unique flavor profile that is often described as umami, or savory.
Umami is one of the five basic tastes that humans can perceive, along with sweet, sour, salty, and bitter. It is derived from glutamate, an amino acid that is abundant in fungi, and it enhances the flavor of foods and makes them more satisfying.
Fungi can also be used to create innovative food products that mimic the texture and appearance of animal products.
For example, fungal biomass can be processed into burger patties that have a similar mouthfeel and juiciness to meat burgers.
Fungal burgers can also be seasoned with spices and herbs to create different flavors. They are not only delicious, but also more sustainable than meat burgers in terms of greenhouse gas emissions, land use, water consumption, and animal welfare.
Fungi have the potential to transform our food systems by providing a sustainable and tasty alternative to conventional animal products.
It can produce high-quality protein and bioactive compounds on various substrates with low environmental impact, and can also be used to create innovative food products that mimic the texture and appearance of animal products.
By incorporating fungi into our diets, we can improve our health and well-being while reducing our ecological footprint.
