Mycotoxin risk management in maize gluten meal

Area of Science:

• Agricultural Science
• Food Science
• Animal Nutrition

Background:

• Maize gluten meal (MGM) is a protein-rich co-product of maize wet milling, widely used in animal feed.
• Global prevalence of mycotoxins in maize poses risks, as processing can concentrate these toxins in MGM.
• Mycotoxin contamination affects animal health and can transfer to animal products.

Purpose of the Study:

• To review mycotoxin occurrence in maize.
• To examine mycotoxin distribution during MGM production.
• To summarize mycotoxin risk management strategies for MGM.

Main Methods:

• Comprehensive literature review on mycotoxins in maize and MGM.
• Analysis of mycotoxin distribution during the wet milling process.
• Evaluation of risk management strategies, including agricultural practices and processing interventions.

Main Results:

• Mycotoxins are a significant challenge for MGM utilization in animal feed.
• Effective control requires a systematic approach, including Good Agricultural Practices (GAP) and processing interventions.
• Degradation using SO2 and lactic acid bacteria (LAB), and emerging technologies show promise for mycotoxin mitigation.

Conclusions:

• Mycotoxin control is crucial for the safe and economic use of MGM in animal feed.
• A holistic, risk-based, seed-to-MGM-feed approach is necessary for effective mycotoxin reduction and decontamination.
• Implementing systematic strategies can reduce costs and negative health impacts associated with mycotoxin-contaminated MGM.
