MUSHROOMS AS A FUNCTIONAL FOOD: NUTRITIONAL VALUE, MINERAL COMPOSITION AND THE IMPORTANCE OF INDUSTRIAL GROWING IN CONTROLLED CONDITIONS
Edible mushrooms are an important component of the modern food system due to the combination of high nutrient density, low calorie content and the presence of biologically active compounds. Mushrooms contain proteins, dietary fiber, potassium, selenium, copper, riboflavin, niacin, choline and other trace elements, which determines their role as a functional food product. Modern studies demonstrate the potential of mushrooms to improve the quality of the diet without a significant increase in calorie content or saturated fat content.
Of particular importance is the industrial cultivation of mushrooms under controlled conditions, which allows to ensure stable product quality, microbiological safety and predicted yield indicators. At the same time, the nutritional value of mushrooms largely depends on the quality of compost, microclimate parameters, ventilation systems, sanitary control, timely cooling after gathering and logistics conditions.
The article summarizes modern scientific data on the nutritional value of mushrooms, their mineral composition and the role of controlled industrial cultivation in the formation of a high-quality final product. Special attention is paid to the author's practical production experience and elements of his own methodology for industrial cultivation of mushrooms under controlled conditions, formed on the basis of many years of work in the agricultural sector. To illustrate the nutritional value and mineral composition of mushrooms was used information about the two-spore champignon (Agaricus bisporus), which is one of the most common species in modern industrial mushroom cultivation.
Introduction
In recent years, mushrooms have increasingly been considered not only as a traditional food product, but also as an important element of functional nutrition. The growing interest in mushrooms is associated with a change in consumer trends towards products with high nutrient density, low calorie content and potential beneficial properties for human health [1].
Unlike vegetables, mushrooms biologically belong to a separate kingdom (Fungi) and have a unique composition of nutrients. Edible mushrooms are characterized by low fat and cholesterol content, contain dietary fiber, amino acids, minerals, B vitamins, as well as biologically active compounds, including polysaccharides, phenolic components and antioxidants [1].
Among the most common types of industrial cultivation, a special place is occupied by the two-spore mushroom (Agaricus bisporus), which is one of the most widespread mushrooms in global agricultural production. Its popularity is explained by the stability of yield, high adaptability to controlled cultivation and significant nutritional value.
Scientific data indicate that regular inclusion of mushrooms to the diet can contribute to an increase in the intake of potassium, selenium, copper, riboflavin, niacin and choline without a significant increase in the energy value of food. That is why mushrooms are considered a promising component of modern healthy nutrition systems [2].
A feature of this work is the combination of modern scientific data with the author's practical experience in the field of industrial mushroom cultivation under controlled conditions. The presented approaches are partly based on many years of production observations and elements of the author's methodology for managing microclimate, compost, sanitary processes and logistics of mushroom production. This approach allows us to consider the quality of mushrooms not only from the perspective of food science, but also as the result of a complex technological system.
Materials and Methods
The study was carried out in the format of an analytical review of modern scientific sources devoted to the nutritional value of edible mushrooms, their mineral composition and the features of industrial cultivation under controlled conditions. In addition to theoretical sources, the information presented in the work is also based on the practical application of modern methods.
During the preparation of the article, the following were used:
- International scientific publications of 2023–2026;
- Materials from the PubMed, Frontiers, ScienceDirect and Springer databases;
- The official USDA FoodData Central database on the nutritional value of products;
- Modern review works on mushroom biofortification and functional nutrition;
- Practical experience of industrial cultivation of mushrooms under controlled conditions.
The analysis was carried out by comparing the results of modern studies on:
- the nutritional composition of mushrooms;
- the content of mineral elements;
- the role of cultivation conditions;
- the influence of microclimate and logistics on product quality;
- the importance of controlled cultivation for the stability of the nutritional characteristics of mushrooms.
Nutritional and Mineral Composition of Mushrooms
Edible mushrooms are a source of a wide range of nutrients and trace elements. Particular attention in modern studies is paid to the high content of potassium, selenium, copper, riboflavin and niacin [3].
According to USDA FoodData Central, edible mushrooms (consider the white mushroom species Agaricus bisporus) contain a small amount of calories and fat, but provide the body with important trace elements and B vitamins. Such characteristics make mushrooms a promising component of diets with controlled energy value [4].

Of particular importance is the ability of mushrooms to accumulate mineral elements from the substrate. Modern studies demonstrate that fungi can be an effective platform for biofortification with selenium, zinc and other trace elements [5].
Selenium is one of the most valuable trace elements in the composition of mushrooms, as it is involved in the antioxidant defense of the body, the functioning of the immune system and the regulation of a number of metabolic processes. Studies show that selenium-enriched fungi may have increased antioxidant properties and potential as a functional food product [3].

In addition to the mineral composition, fungi contain bioactive components, including polysaccharides, phenolic compounds and ergosterol, which can affect the antioxidant and immunomodulatory properties of the product [6]. Thus, modern studies confirm that mushrooms are not only a low-calorie product, but also an important source of functional nutrients.
Influence of Controlled Cultivation on Product Quality
The nutritional value and marketable quality of mushrooms largely depend on the cultivation technology. Unlike many vegetable crops, mushrooms are extremely sensitive to changes in the microclimate, the sanitary condition of production facilities and the parameters of the substrate.

Industrial cultivation of champignons under controlled conditions involves constant management of the following parameters:
- Compost temperature;
- Air temperature;
- Humidity level;
- CO₂ concentration;
- Ventilation;
- Sanitary condition of chambers;
- Fruiting phases;
- Cooling rate after harvest;
- Transportation and storage conditions.
Violation of at least one of these parameters can negatively affect both yield and nutritional value and appearance of products.
Modern studies confirm that controlled cultivation ensures the stability of mushroom quality, reduces microbiological risks and increases production efficiency [7].
Post-harvest processing is also an important factor. Due to the high moisture content, mushrooms quickly lose density, marketability and freshness. That is why rapid cooling and a controlled logistics chain are critical to maintaining product quality.

Results
Analysis of modern scientific sources, as well as more than 20 years of personal practical experience of the author showed that edible mushrooms have significant potential as a functional food product due to the combination of low calorie content, high nutrient density and the presence of biologically active compounds.
It was established that:
- Mushrooms are a source of potassium, selenium, copper, riboflavin and niacin;
- Controlled cultivation allows to ensure the stability of product quality;
- Microclimate parameters directly affect yield and commercial characteristics;
- Modern biofortification technologies allow to increase the content of individual microelements in mushrooms;
- Rapid cooling and proper logistics are critically important for preserving quality after harvest.
The results obtained confirm the prospects of using mushrooms in modern systems of healthy nutrition and functional products.
Conclusion
Modern research confirms that edible mushrooms can be considered not only as a traditional food product, but also as a promising component of functional nutrition due to the combination of low calorie content, high nutrient density and content of biologically active compounds.
At the same time, the results of the analysis of scientific sources and the author's practical production experience indicate that the final quality of mushroom products is formed not only by the biological characteristics of the culture, but also by the accuracy of technological management at all stages of production. The stability of the mineral composition, product characteristics and safety of products directly depends on the quality of compost, microclimate parameters, sanitary control, ventilation systems and post-harvest logistics.
The practical approaches formed by the author in the process of many years of work with industrial mushroom cultivation under controlled conditions demonstrate the effectiveness of a comprehensive production model in which biological, technological and logistical processes function as a single system. This approach allows us to ensure stable product quality, predicted yields, and compliance with modern requirements for food safety and functional nutrition.
