  1. High Temperature Natural Antioxidant Improves Soy Oil for Frying Kathleen Warner National Center for Agricultural Utilization Research Agricultural Research Service U.S. Department of Agriculture Peoria, IL USA Marta Meta Gehring Product Development ELVISEM AG Rotkreuz, Switzerland

  2. Objectives • To determine frying stability of soybean oil with EPT-OILShieldTM, a natural citric acid-based antioxidant • To determine storage stability of tortilla chips • fried in soybean oil with EPT-OILShieldTM, a natural citric acid-based antioxidant

  3. Materials • EPT-OILShieldTM at 0%, 0.05% and 0.5% • specially prepared citric acid • potassium sulphate at adjuvant dose • aluminum silicate at adjuvant dose • formulated by Energy Potential Technology (EPT) • fine white powder • Commercially processed soybean oil (no added antioxidants) • Raw, white corn tortillas

  4. Methods • Intermittent batch frying of tortilla chips at 180oC for a total of 65 hr heating/frying in 2 L fryer; makeup oil added • Tortilla chips aged at 25C for up to 4 months • Frying oil analyses • Free fatty acids (AOCS Ca 5a-40) • Total polar compounds (AOCS Cd 20-91) • Tortilla chips analyses • Trained, experienced, analytical descriptive sensory panel • Hexanal by GC headspace

  5. Conclusions • Addition of 0.05% EPT-OILShieldTM to soybean oil significantly improved the frying stability compared to a soybean oil control • Addition of 0.05% EPT-OILShieldTM to soybean oil significantly improved the storage stability of tortilla chips fried in this oil compared to a soybean oil control • EPT-OILShieldTM is high temperature resistant (180C)
