Phytate Extraction from Corn Ethanol Coproducts

詳細技術說明

Extracting Phytate from CornAn easy, scalable method extracts high yields of purified, marketable phytate from ethanol waste streams. Phytate, a coproduct of ethanol production that is not digestible by many livestock, increases phosphate pollution from livestock waste. The efficient phytate extraction process is selective and improves livestock feed properties of dry distillers grains (DDGS) by removing “antinutrient” phytate from DDGS while retaining free inorganic phosphate, an important nutrient. This simple process can be incorporated into current corn ethanol production processes to extract high-value phytate and use the remaining solids as animal feed ingredients, thereby both reducing pollutants and adding value from previously wasted materials.Improving Dry Distillers GrainsThis method differs from current methods in several ways. First, it obtains higher phytate yield and relies on ion-exchange methods instead of bulk pH modification and solvent extraction. Currently-used phytase enzymes remove phytate from DDGS, adding cost to animal feeds or other DDGS derived products. In addition, by destroying valuable phytate, these enzymes prevent phytate purification and its potential revenue as a high-value chemical.BENEFITS AND FEATURES:Removes the indigestible portion of phosphorus from DDGS, thereby decreasing phosphate excretion/pollutionIncreases revenue and profitability by creating phytate-based high value co-productsImproves DDGS nutrient quality by removing the antinutrient phytate, which chelates essential metalsReduces water treatment costs, fertilizer waste, suboptimal phosphate concentration in feedBetter alternative to phytase enzymes that add cost while destroying valuable phytateMay improve ethanol yieldAPPLICATIONS:Enhancing livestock feedRaw material source for production of valuable inositolPhytate salts can be sold as natural anti-oxidant and chelating agents in food, beverages, cosmetics, anti-corrosive and other applicationsImproved ethanol yield, reduced phosphate release into environmentReduced ethanol plant maintenance costs through reduction of scale on piping and vesselsPhase of Development - Lab scale demonstration
