Removability of ZEN (0.5 mg/kg) with EDRs (solid line) and adsorbents (dotted line) in poultry gastrointestinal simulations (0 to 2 h for crop and glandular stomach simulation, 2 to 2.5 h for gizzard simulation, 2.5 to 4.5 h for small intestine simulation). ◆:0.05% EDR1; ■: 0.1% EDR2; ▲: 0.1% EDR3; ×: 0.1% EDR4; □: 0.2% EDR5; ●: 0.2% Adsorbent1; +: 0.2% Adsorbent2. a,b,c,d Means of the same column (time point) without the same superscripts differ (p < 0.05). AGJ: Artificial gastric juice; AIJ: Artificial intestinal juice; DON: Deoxynivalenol; EDR: Enzyme degradation reagents; ZEN: Zearalenone.
