Kombucha: Starter Cultures / Process Development / Analysis

Kombucha is one of the oldest traditionally fermented beverages in the world. It is a sweetened tea, which achieves its characteristic aroma by symbiotically living yeasts and acetic acid bacteria.  Due to its sweet-sour, aromatic character and not least because of the functional ingredients formed by the microorganisms, Kombucha enjoys increasing popularity.

Particularly in recent years the interest in Kombucha production has increased in the beverage industry as well as in the craft scene.
Taking a closer look at the course of a mixed fermentation, an enormous complexity manifests itself at the microbial level. The adaptation of the experience-based knowledge and a process transfer of Kombucha's traditional craftsmanship to a standardized and controlled industrial scale poses challenges for a producer. Therefore, appropriate quality assurance along the Kombucha production chain is essential to obtain a safe product that meets regulatory requirements.
