Cause of Flavour

Imparted via poor cleaning in process (CIP) systems - cleaning agent is run through beverage processing systems and it is not effectively removed via rinsing. Contact with raw water, raw material and finished product to the residual cleaning agent will impart medicinal like flavours.

Medicinal like flavours can also be imparted at the consumer delivery level - via poorly cleaned lines at fountains and other dispensary systems.

This can occur in any beverage alcoholic and non-alcoholic alike.

FlavorActiV's GMP Flavour Reference Standard Medicinal has undergone evaluation by the same research team behind the first World Coffee Research Lexicon, and has been approved for inclusion within the latest World Coffee Research Lexicon as a validated coffee flavour reference.

In early 2014, together with two of the coffee industry’s leading organisations, FlavorActiV developed and launched an advanced Calibrating Coffee Sensory Plan to provide cupper training, cupper calibration and coffee tools throughout the coffee supply chain. In 2016 FlavorActiV partnered with World Coffee Research to validate the use of FlavorActiV's GMP Flavour Standards as reference standards within WCR's lexicon. FlavorActiV's Medicinal is of the 24 validated flavour reference standards.
