Hydri‑Maize™ Color Guard
Sustainable Color Protection for High‑Quality DDGs
Hydri‑Maize™ Color Guard delivers on that commitment by helping ethanol producers create more consistent, higher‑value co‑products with reduced environmental impact.
Engineered for modern biofuel facilities, Hydri‑Maize™ Color Guard prevents the unwanted darkening of syrup and DDGS after oil removal, improving product quality, supporting customer success, and strengthening plant performance.
What Causes Color Degradation?
Color quality is a key indicator of performance and value in thin stillage streams, oil‑removed syrup systems, DDG quality initiatives, and plants pursuing higher‑value coproducts. Several operational factors can drive unwanted darkening or variability:
Passing Excess Sugars
Unconverted or excess sugars can accelerate Maillard reactions, leading to darker color in thin stillage, syrup, and finished DDGS—reducing consistency and coproduct value.
Extended Retention Time in Syrup Tanks
Process upsets that increase residence time raise the likelihood of caramelization and thermal degradation, directly impacting syrup color and downstream DDG appearance.
Next‑Generation Enzyme Use
While advanced enzymes improve conversion efficiency, they can shift chemical balances in stillage and syrup systems, creating variation in color if not tightly controlled.
Plant Shutdowns and Startups
Idle tanks and fluctuating temperatures during shutdowns can cause material darkening, carryover issues, and inconsistent quality in early‑run coproducts.
What are the Risks of Discolored DDGS?
Discolored DDGS can reduce product value and create downstream challenges for plants focused on quality and higher‑value coproducts.
Blending Good and Bad DDGs
Mixing darker DDGS with lighter material to improve overall color lowers average quality and hides process issues that need attention.
Customer Rejection
Buyers often judge DDG quality by appearance. Dark loads are more likely to be rejected, disrupting shipments and damaging trust.
Required Discounts
When customers do accept darker DDGS, it typically requires a price discount—directly reducing co-product revenue and margins.
