Ascorbic Acid / Vitamin C Technology
Chemical Process Route
ENCO ENGINEERING's technology for ascorbic acid is based on the classical Reichstein synthesis. The conventional process has however been further developed using newest technologies, particularly to reduce consumption figures and to improve environmental conditions. This was partly done in cooperation with reputed companies specialized in their particular fields.

Biotechnological Process Route
It is generally expected that biotechnological processes will be the future for the production of ascorbic acid. All presently known biotechnological processes are leading to 2-keto-L-gulonic acid (KGA) as an intermediate, with either glucose or sorbitol as a starting material.
The downstream process from KGA to ascorbic acid is then following a chemical route, similar to the Reichstein process. We have further developed our process in this respect. It is especially suitable to use also KGA with higher impurity content, as it is frequently obtained from biological processes. Samples from different sources have been tested and the process has been adapted and optimized accordingly. A corresponding new patent has recently been filed.
COMBINED BIOLOGICAL / CHEMICAL PROCESS ROUTE
(Starting Material: 2-Keto-L-gulonic Acid)
Depending on the source of the ketogulonic acid, either from a biological or a chemical process, the downstream process will slightly be modified. It is however following the same principal route.
Esterification / Lactonization
ENCO ENGINEERING's process is partly covered by patents. It gives the following advantages:
Isolation / Purification
The ascorbic acid product is fulfilling the requirements of the newest British and U.S. Pharmacopeia.
