Summary
Preventing mycotoxin production in cereals involves post-harvest strategies like drying and refrigeration. Effective preservation methods completely inhibit mold growth, as indicated by ergosterol levels, to ensure feed safety.
Area of Science:
- Agricultural Science
- Food Science
- Mycology
Context:
- Mycotoxin contamination in cereals poses significant risks to animal and human health.
- Current pre-harvest strategies for reducing mycotoxin production are limited.
- Post-harvest management is crucial for controlling fungal growth and mycotoxin development.
Purpose:
- To review and evaluate methods for inhibiting fungal growth and mycotoxin production in cereals post-harvest.
- To highlight the importance of complete mold inhibition for effective preservation.
- To provide guidance on optimal drying, storage, and chemical preservation techniques.
Summary:
- Breeding resistant cereal varieties is a promising pre-harvest approach.
- Post-harvest control includes drying, refrigeration, chemical preservation (propionic acid, urea), and airtight storage.
- Ergosterol serves as a reliable indicator for quantifying fungal growth and assessing preservation effectiveness.
- Effective preservation completely inhibits mold development, preventing mycotoxin synthesis, as demonstrated in refrigerated wheat storage.
Impact:
- Informed selection of preservation strategies to minimize mycotoxin risks in stored cereals.
- Guidelines for optimizing drying parameters (depth, air velocity) and refrigerated storage conditions (moisture, temperature).
- Recommendations for appropriate chemical preservative dosages, such as propionic acid, to prevent mold proliferation.
- Enhanced food and feed safety through effective control of fungal contaminants and mycotoxins.
