Pure, sometimes called “absolute” ethanol, is 100% ethanol. Absolute food grade ethanol is preferred for many common techniques in food research and development, including food grade extraction and fraction isolation, or food grade synthesis.For food grade synthesis, the presence of water could result in undesired byproducts. For example, many volatile organic compounds are synthesized in ethanol, and can be added to food to manipulate flavor and aroma. The use of food grade solvents in all of these applications ensures the safety and purity of food and food standards for consumers. Buy Food Grade Ethanol 200 Proof 100% Pure Alcohol In Bulk Sizes, Non-Denatured Ethyl Alcohol Products For Sale, Packaged In Bottles, Drums, Totes, Pallets.
