What is corn ethanol?

In different contexts and industries, corn ethanol is also referred to as Corn alcohol, Organic corn ethanol, Corn-based alcohol and Corn ethyl alcohol. It is produced from corn biomass through the fermentation and distillation of ethanol, usually by a process known as dry milling or (less commonly nowadays) wet milling.

Corn ethanol is a renewable fuel that is blended with gasoline to create fuel mixtures, such as E10 (10% ethanol, 90% gasoline), E85 (85% ethanol, 15% gasoline), etc. E10 has an increasing market share in countries across the world and in some, such as Sweden and the UK, is now the official standard product at gas stations.

How is organic corn ethanol made?

Let’s take a process for making 99% corn ethanol. First the corn is ground to a fine consistency so the starch matter and kernel are exposed. Water and enzymes are then added to create ‘mash’. The mash is heated to 185 degrees so that the corn starch breaks down into fermentable sugars. It is then cooled to 92 degrees and yeast added. This causes fermentation, whereby the sugars turn to alcohol. The resulting mixture, which is 17-18% alcohol and known as ‘beer’, is pumped to a distillation column and heated. The alcohol exits the distillation column as 95% alcohol vapour and moves to a 2nd distillation stage, where it distils to 195 proof alcohol. It then passes through a condenser which turns the vapour to liquid. Finally, the liquid passes through a molecular sieving process to extract the remaining water, leaving a final ethanol product that is 200 proof and 99% alcohol.

According to research by Cornell University, it takes about 11.84kg of corn to produce 1 gallon of ethanol.

Corn ethanol - advantages and disadvantages

Corn ethanol results in up to 50% fewer greenhouse gas emissions well-to-wheel than gasoline. It is also fully biodegradable and burns off more environmentally cleanly than gasoline or diesel fuel. Nevertheless, the environmental benefits of corn-based biofuels remain disputed.

First, corn ethanol as fuel also has a lower mileage than oil. It also has a far lower EROI (energy returned on energy invested) than oil. The EROI for corn ethanol is about 1.5:1 and for oil about 11:1, though with technological advances it is believed this gap may shrink significantly.

Secondly, some research suggests corn ethanol in fact produces more carbon emissions per unit of energy than gasoline, once you factor in fertiliser use and changes in land use.On land use, there is the additional criticism that the huge areas of arable land used to produce corn for ethanol (some 25% of all US arable acreage, for example) is therefore unavailable to grow corn or other crops for human or animal consumption.

All in all, however, we feel corn ethanol benefits the global fuel mix. An E10 blend typically decreases CO and CO2 emissions by some 30%. And on the criticism that ethanol uses more energy than it provides, the evidence is conflicting. Moreover, most governments and experts ultimately feel the benefits of using corn ethanol-based fuels outweigh the potential disadvantages.

Corn ethanol uses

Corn ethanol is clear, colourless and odourless, making it ideal for use in a range of food and drink products. For example as a base spirit in gin, vodka and corn whiskey. It also make it a popular ingredient in personal hygiene products, such as hand sanitisers. And finally, corn ethanol is also used in animal feed, as a solvent for flavourings and as a preservative. Across the globe, alcohol made from corn is also widely used as a component in vehicle fuel, including 98% of all fuel used in cars in the US.

Denaturants for corn alcohol

Not all corn alcohol is used to produce food or drinks. If you do not use raw alcohol to produce food or drinks, we can denature it for you. In that case, the product will be exempt from excise duty. You can choose from the following denaturing agents:

  • DEP
  • MEK
  • Bitrex
  • TSDA 1-9
  • TBA
  • IPA
  • Euro Denatured
  • Tipo A-D

Choose your own combination of denaturants to create the customised neutral alcohol you need or contact us to discuss the various options.
