ISSUE FOCUS FEED & ADDITIVE MAGAZINE December 2025 35 • Hot conditions (summer): Lower viscosity → pumps deliver more antioxidant → overdosing Consequences include: • Winter: Increased fat oxidation, higher peroxide values, reduced shelf life, potential product recalls • Summer: Excess antioxidant levels, regulatory compliance risks, and higher treatment costs. HOW TO SECURE THE RIGHT ANTIOXIDANT APPLICATION Main rules to respect are good practices in term of: 1. Application and pump calibration 2. Weather anticipation 3. Liquid antioxidant temperature control Liquid application practices Before initial use, pump calibration should be performed at the same temperature as that of the intended liquid application. It is essential to record the liquid temperature and document it in the calibration report. Whenever there is a change in temperature, recalibrate the pump accordingly. Regularly monitor antioxidant consumption as per established guidelines. Always apply liquid antioxidants at the originally specified temperature, typically within the range of 20ºC to 30ºC. Weather condition changes It is essential to maintain consistent control and monitoring of the liquid antioxidant temperature both prior to and during application. Temperature sensors are typically used in the antioxidant Intermediate Bulk Container (IBC), drum, or bidon, while certain flowmeters can also relay temperature data. All collected information can be managed via a Programmable Logic Controller (PLC) or directly through connected technologies such as Kemin sciORIANTM.3 This system enables real-time collection of data including temperature, flow rate, quantity administered, bulk and stock levels, and pump status. Operators actively oversee temperature and application in real time. Should any issues arise, such as temperature reduction or pump failure, alert notifications are sent by email. All data is recorded to ensure full traceability. Prior to installing a new IBC, drum, or Jerrycan, it is important to verify the temperature. As a standard procedure, allow the container to acclimate for several days near the existing antioxidant liquid. If required, gently warm the container to reach the desired temperature. Temperature control As mentioned above, it’s crucial to maintain the right liquid antioxidant temperature in the IBC/ Photo: Freepik
