Sharing our knowledge and experience.

Technology for Organic Acid Production

Owing to their organoleptic, physiological and chemical properties, organic acids are employed in wide areas of application across various industries. Organic acids are common ingredients in food and beverage products, but are also basic components in the manufacturing of personal care products, plastics, detergents and in many other end-user industries.

On this page you can find out how organic acids are produced and how Vogelbusch can contribute to setting up an organic acid plant.

How are organic acids made?

Adapted microorganisms are used to transform carbohydrates from natural origin into organic acids. They are metabolic products of specific bacteria, yeasts and fungi, which can be cultivated in a range of substrates containing carbohydrates such as glucose, saccharose or ethanol. Following microbial conversion, the product is subject to isolation, purification and finishing steps on the basis of application.

Organic acid know-how and technology

Vogelbusch offers proprietary technology for the production of citric acid and acetic acid (vinegar) and has the process and engineering knowledge about all aspects of facility design and implementation.

With our accumulated company know-how we are also available to engineer plants applying your own or third party processes, for instance for lactic, gluconic, itaconic and ascorbic acid as well as amino acids.

Having detailed knowledge and insights into biotechnological processes, our specialists can evaluate available 3rd party conversion technology, scale it up to industrial levels or integrate it with our unit operations, to provide you with the end-to-end process from raw material to final product.
