Our Products

Our AFYNERIE® technology produces a family of 7 completely biosourced organic acids: carboxylic acids containing from 2 to 6 carbon atoms. We manufacture our high-quality products through fermentation, and we achieve more than 99% purity for certain applications. This wide range of organic acids enables AFYREN to enter diversified and global markets.

Our natural molecules are identical to the ones that industries usually use and made from petroleum, thereby rendering them simply and instantaneously replaceable. Our 100% biosourced molecules allow you to reduce your environmental impact without affecting the performance of your products.

Acetic acid is the principal component of vinegar and gives it its typical sourness. In application as a natural flavoring substance, it can be used in the formulation of butter, cheese, chocolate, grape and strawberry flavors. It is widely used as a raw material for the production of a range of acetates with applications in flavors and fragrances.

Butyric Acid is a feed material that is being used in animal feed formulations. This product is well known for its properties which support the reduction of the inflammation inside of an animal digestive tract. As such it enables the feed industry to provide alternative solutions to reduce the medication in livestock. (That way the end consumer gets an animal product without antibiotic residues).

Isobutyric acid and its volatile esters occur naturally in a wide variety of foods. It has a strong, buttery odour and a fruity taste when diluted. It has many applications as a natural flavoring substance for creamy-fruity tastes. It is also a raw material for the production of natural fruit flavorings.
Isobutyric acid esters are used in cosmetic products and flavorings and perfumes.

Valeric Acid

Valeric acid is a five-carbon saturated monocarboxylic acid that is widely used in esters for synthetic lubricants in refrigeration and in aeronautics turbines.

Valeric acid is a minor constituent of the perennial flowering plant Valerian (Valeriana officinalis), from which it takes its name. It has a very strong, penetrating, acidic odour and a pleasant fruity taste when diluted. Its main use is the synthesis of its esters. The salts and esters of valeric acid are known as valerates or pentanoates and are widely used in cosmetics and perfumes.Valeric Acid is a crucial component of Polyol Esters formulations that are used in applications of refrigeration and air conditioning such as industrial refrigeration, refrigeration systems for food storage or mobile and stationary air conditioning.

Propionic acid has an acidic profile, and the resulting propionic acid esters have a fruity smell. They can be used as natural flavoring substances or as solvents in many flavor and fragrance applications.
Propionic acid is mainly used in bread and bakery products as a mould inhibitor. It is either introduced with the yeast or sprayed onto the bread to prevent moisture from penetrating the loaf.
