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.

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.

Citric Acid Plant in Kermanshah
KIMIA GHARB GOSTAR Industries Co. - Kermanshah, Iran

The plant has a capacity of 36 tons per day and is the first citric acid plant built in Iran. It is suitable for processing of raw sugar and sugar beet molasses. The process concept allows for a choice between production of either of the two commercially available forms of...

Citric Acid Plant near Cairo
CITRO MISR Co. - 10th of Ramadan City, Egypt

Raw sugar from local production was the substrate of choice for Citro Misr Co. of Egypt. This raw material required a new approach in the fermentation process to assure the economic feasibility of the plant. The spore cultivation was adapted and the fructose utilization was optimized for the substrate. Products include...
