Send EmailDistillers Dried Grains with Solubles, DDGS
DDGS stands for Distillers Dried Grains with Solubles, a valuable co-product of ethanol production. It’s created after fermenting grains like corn, wheat, or rice to produce ethanol, then removing the alcohol through distillation. What remains is a nutrient-rich byproduct used primarily in animal feed.
🌾 What Is DDGS?
-
Origin: After ethanol is extracted from fermented grains, the leftover solids and condensed solubles are dried and granulated into DDGS.
-
Composition: High in protein, fiber, fat, vitamins, and amino acids.
-
Form: Typically a golden-brown, granular feed ingredient.
🐄 Applications
| Sector | Use of DDGS |
|---|---|
| Livestock Feed | Cattle, swine, poultry — as a protein and energy source |
| Aquaculture | Fish feed additive |
| Pet Food | Supplement in high-protein formulations |
| Fertilizer | Occasionally used as organic soil amendment |
🧪 Nutritional Highlights
-
Protein: ~25–30%
-
Fat: ~10–12%
-
Fiber: ~8–12%
-
Moisture: ~10% (after drying)
-
Digestibility: Highly digestible for ruminants
🌍 Economic & Environmental Benefits
-
Cost-effective: Cheaper than traditional protein sources like soybean meal
-
Sustainable: Utilizes waste from ethanol production, reducing environmental impact
-
Exportable: Countries like India and the U.S. export DDGS globally
⚠️ Considerations
-
Mycotoxins: Must be monitored to ensure feed safety
-
GMO Concerns: Some producers offer non-GMO DDGS for premium markets
-
Storage: Requires dry, cool conditions to prevent spoilage
DDGS (Distillers Dried Grains with Solubles) is a complex mixture rather than a single, pure chemical compound. Therefore, it does not have a unique CAS number like ethanol (which is 64-17-5).
However, in regulatory and industrial contexts, DDGS may be referenced under broader categories or assigned group CAS numbers depending on its source (e.g., corn-based DDGS, wheat-based DDGS). These identifiers are typically used in feed safety databases or trade documentation, not in chemical registries.
