In many plants, valuable oil is being left behind in wet cake, fiber streams and other parts of the process that operators historically lacked visibility into.<br><br>These losses are often interconnected. Changes in fermentation performance can affect downstream separation efficiency, while variability in feedstock or process conditions may influence oil release and recovery throughout the plant.<br><br>There is no one-size-fits-all solution. \u201cEvery ethanol plant has unique requirements for maximizing value,\u201d says\u00a0Teunissen. Many plants have historically focused on centrifuge settings and mechanical separation improvements.

Improving distillers <a href=\"https:\/\/www.iff.com\/es\/media\/stories\/enhancing-corn-oil-recovery\/\" target=\"_blank\" rel=\"noreferrer noopener\">corn oil recovery<\/a> is not simply about increasing output. It is also about extracting more value from existing feedstocks while reducing avoidable process loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fuel ethanol plants are already designed around strong coproduct utilization systems, with materials typically recycled back into the process or directed into additional value streams rather than discarded.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For producers already focused on maximizing coproduct value, recovering more usable oil from existing feedstocks is a natural extension of the industry\u2019s broader efficiency goals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Efficient recovery can help producers improve resource utilization, reduce avoidable waste and lower energy intensity per unit of output while strengthening both plant economics and carbon performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These improvements are becoming more important as producers compete in low-carbon fuel markets where carbon intensity increasingly influences profitability and market access.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the same time, outcomes remain highly plant-specific. The strongest results typically come from integrated optimization strategies tailored to individual operating conditions rather than one-size-fits-all solutions.<\/p>\n\n\n\n<h2 id=\"h-creating-more-value-from-ethanol-coproducts\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Creating_More_Value_From_Ethanol_Coproducts\"><\/span>Creating More Value From Ethanol Coproducts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Modern ethanol production depends on maximizing value across the entire plant rather than focusing exclusively on ethanol yield. Distillers <a href=\"https:\/\/www.iff.com\/es\/media\/stories\/enhancing-corn-oil-recovery\/\" target=\"_blank\" rel=\"noreferrer noopener\">corn oil recovery<\/a> has become an important part of that strategy because improved coproduct performance means higher yield and improved plant economics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Improving recovery can increase yield, reduce oil loss to wet cake and support more stable plant operations with lower feedstock variability from batch to batch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Operational visibility is becoming a strategic part of this process. Understanding where oil losses occur allows producers to make more targeted operational adjustments and identify inefficiencies that may otherwise remain hidden within normal plant variability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As low-carbon fuel markets continue evolving, producers are looking for ways to improve yield, reduce waste and strengthen operational resilience simultaneously.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More efficient DCO recovery is becoming an essential part of that effort because it sits at the intersection of resource efficiency, <a href=\"https:\/\/www.iff.com\/es\/sustainability\/\" target=\"_blank\" rel=\"noreferrer noopener\">sustainability<\/a> and plant profitability.<\/p>\n\n\n\n<h2 id=\"h-the-future-of-distillers-corn-oil-recovery\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Future_of_Distillers_Corn_Oil_Recovery\"><\/span>The Future of Distillers Corn Oil Recovery<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The next phase of DCO optimization will likely rely on increasingly integrated production systems that combine biotechnology, process analysis and system-level understanding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than relying on isolated mechanical adjustments, producers are moving toward more data-driven strategies capable of identifying inefficiencies across the entire operation in real time. Advanced <a href=\"https:\/\/www.iff.com\/es\/grain-processing\/biotechnology-and-improving-corn-oil-recovery\/\" target=\"_blank\" rel=\"noreferrer noopener\">enzyme technologies<\/a> will continue evolving alongside improved monitoring systems, separation technologies and operational controls.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No two ethanol plants operate exactly alike, which is why plant-specific optimization remains critical. The most effective recovery strategies are built around understanding where value is lost throughout the process and applying targeted solutions across the system as a whole.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The industry still has substantial opportunity to recover more value from existing feedstocks while improving yield consistency and carbon performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the average ethanol plant is recovering only about half of its potential distillers corn oil yield, then one of the renewable fuels industry\u2019s greatest opportunities may already exist within current operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Capturing more of that unrealized oil can help producers strengthen plant economics while improving the overall efficiency and carbon performance of <a href=\"https:\/\/ethanolrfa.org\/file\/2921\/coproducts_brief_2025.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">renewable fuel<\/a> production, helping unlock more of the value already contained within every bushel of corn.<\/p>\n\n\n<div class=\"m-block blog-cta\"  >\n            <div class=\"blog-cta__content\">\n                                        <div class=\"blog-cta__title\">\n                    Connect with IFF Grain Processing Experts                <\/div>\n                    <\/div>\n                <a href=\"\/es\/grain-processing\/contact\/\" target=\"_blank\" class=\"c-btn -normal -primary has-icon icon-right\">Contact Our Team <svg width=\"30\" height=\"30\" class=\"icon icon-lib-icon-arrow1\" aria-hidden=\"true\" role=\"img\"><use xlink:href=\"#lib-icon-arrow1\"><\/use><\/svg><\/a>    <\/div>\n\n\n\n<h2 id=\"h-frequently-asked-questions\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1780588510888\"><strong class=\"schema-faq-question\">What is distillers corn oil?<\/strong> <p class=\"schema-faq-answer\">Distillers corn oil is a coproduct generated during ethanol production that can be used in renewable diesel, <a href=\"https:\/\/www.ars.usda.gov\/research\/publications\/publication\/?seqNo115=414947\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">biodiesel<\/a>, livestock feed and other industrial applications.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780588541143\"><strong class=\"schema-faq-question\">Why is distillers corn oil recovery important?<\/strong> <p class=\"schema-faq-answer\">Many ethanol plants recover only about 50\u201360% of total available distillers corn oil yield, meaning valuable recoverable oil may still remain within the process.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780588562502\"><strong class=\"schema-faq-question\">How can ethanol plants improve corn oil recovery?<\/strong> <p class=\"schema-faq-answer\">Producers often combine <a href=\"https:\/\/www.iff.com\/es\/grain-processing\/biotechnology-and-improving-corn-oil-recovery\/\" target=\"_blank\" rel=\"noreferrer noopener\">enzyme technologies<\/a>, fermentation alignment, separation optimization and process mapping to improve recovery across the plant.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780588581583\"><strong class=\"schema-faq-question\">What role do enzymes play in distillers corn oil recovery?<\/strong> <p class=\"schema-faq-answer\">Enzymes help release oil trapped within fiber and protein structures, allowing more oil to become available during downstream separation.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1780588600159\"><strong class=\"schema-faq-question\">How does distillers corn oil recovery support sustainability?<\/strong> <p class=\"schema-faq-answer\">Improving DCO recovery can help producers recover more usable output from the same corn input, reduce avoidable waste and strengthen carbon performance depending on plant-specific operating conditions.<\/p> <\/div> <\/div>","protected":false},"excerpt":{"rendered":"<p>More\u00a0than just a byproduct, distillers corn oil (DCO) is one of the most valuable outputs from an ethanol plant.
