The Voronezh branch of the "Grain Quality Assessment Center" tested a 22-ton batch of Jerusalem artichoke flour for various parameters such as taste, color, moisture, and impurities, as well as toxic elements, radionuclides, and pesticides. The research found that the flour met the requirements of regulatory documents and the importing country. Jerusalem artichoke flour is a valuable raw material for the food industry due to its unique biochemical composition, including inulin, complete protein, pectin, fiber, and minerals.
