Jerusalem artichoke – a perennial root vegetable of the aster family, valued for its rich composition of vitamins, trace elements, and prebiotic fiber (inulin). The tubers have a knobby, elongated shape and can be yellowish, brownish, or reddish; they reach maturity in autumn after the first frosts, but in warm regions they can be harvested in early spring. Tubers can be stored in the refrigerator for up to one or two weeks on damp cloth, and in the freezer for up to three months.
For successful cultivation of Jerusalem artichoke, direct sunlight for at least 6–8 hours a day and loose, slightly alkaline soils are required. The plant grows well in open ground or in containers with drainage; when planting, it is recommended to mix the soil with phosphorus fertilizers (manure, bone meal, fish meal). Regular watering and fertilization help maintain a healthy root system, especially if the light regime is not ideal. It is important to provide good ventilation and avoid water accumulation to prevent fungal diseases.
Jerusalem artichoke has many beneficial properties: inulin stimulates the growth of bifidobacteria, improves digestion, and reduces the risk of intestinal cancer; tubers boost immunity, reduce cholesterol and blood pressure levels, and help control weight due to slow carbohydrates. In cooking, Jerusalem artichoke is used in soups, salads, desserts, as an addition to dishes, or in the form of syrup; dried powder can be added to porridge, drinks, and dairy products. Such a product combines storage convenience with a wide range of applications, making it a valuable addition to a healthy diet.
