Precise control of antinutrients in food can help to enhance the core competitiveness of your products. With professional and rich experience in food testing, Aprofood provides you with one-stop antinutrient analysis solutions to help product compliance, nutritional upgrading, and brand trust building.
Antinutritional factors are natural defense mechanisms that have evolved during plant evolution and are therefore widely present in plant-based foods. These compounds can interfere with the absorption, metabolism, or utilization of essential nutrients. Many traditional food processing methods, such as heating and fermentation, can effectively reduce or destroy antinutrients. For example, soaking beans for 12 hours can reduce phytic acid content by 30–50%, boiling beans for 30 minutes can inactivate over 90% of lectins, roasting nuts can lower tannin levels, and fermenting foods like yogurt and sauerkraut can break down phytic acid and protease inhibitors, thereby improving nutrient bioavailability.
