The alkaline (sodium bicarbonate) flavour standard is used to assess the potency of the sodium bicarbonate character. Sodium bicarbonate appears as an odourless, white, crystalline powder or lump.
The alkaline (sodium bicarbonate) flavour is caused in beverages due to chemical cleaning products increasing pH to alkaline levels. The increase in alkalinity will alter the beverage’s flavour profile and add a detergent-like taint. The flavour profile can be specific to the beverage it occurs in.

Cause of Alkaline Flavour
Alkaline flavour is caused in beverages due to chemical cleaning products increasing pH to alkaline levels. The increase in alkalinity will alter the flavour profile of the beverage and add a detergent-like taint. The flavour profile can be specific to the beverage it occurs in.
Chemical cleaning product interaction occurs due to poor Clean In Process (CIP) systems. Poor rinsing of equipment and pipework before product and raw materials are introduced. Taints are then pulled through into the final product.
Product dispensing that haven’t been properly cleaned can also cause this taint as the product is provided to consumers and is a major problem when fountain systems are delivering products in bars, public houses and restaurants.
Poor CIP systems can impart several different taints and flavours – phenol compounds and bleach-like flavours can also be introduced depending on the cleaning chemicals used.
Alkaline is Beer Flavour Wheel Number: 1310
Typical Alkaline concentration seen: nanograms to milligrams depending on contamination level.
Alkaline is a recommended flavour standard / sensory reference standard of American Society of Brewing Chemists (ASBC) and the European Brewing Chemists (EBC)
FlavorActiV GMP Flavour Standards
Only Pharmaceutical Quality GMP Flavour Standards provide sufficient quality for professional sensory panels to train and validate with.
We produce encapsulated GMP (Pharmaceutical Good Manufacturing Practice) Flavour Standards that are safe to both smell and drink. The compounds within our capsules impart the aroma, taste and mouthfeel of a specific defect or positive flavour into a beverage for the purposes of taster training, calibration and quality control.
Our individual flavour GMP Flavour Standards are sold by flavour, each flavour pack contains 5 capsules, each separately blister packaged. Our sensory kits contain a mixture of flavours, each separately blister packaged, read the product description for flavour details.
We ship globally, and have over 20 years of experience at it. Our GMP Pharmaceutical Flavour Standards are produced to the highest standards, and as such, their shelf-life is strong and their quality consistent.
FlavorActiV’s flavour centre is the world’s only pharmaceutically run facility dedicated to the production of flavour reference standards. The Flavour Centre is a state-of-the-art facility housed within the campus of world-renowned Quay Pharma near Liverpool in the U.K.
The Flavour Centre was designed by FlavorActiV from the ground up at the direct request of global customers as they looked to move away from inferior food grade ‘certified flavour standards’ to GMP Pharma, a standard that ensures safe, stable, traceable, consistent and long shelf-life products.
All FlavorActiV’s industry-leading encapsulated flavour standards are manufactured following GMP at our Flavour Centre. All aspects of manufacture are overseen by Quay Pharma who are audited by the U.S. Food and Drug Administration (FDA) and the U.K. Medicines and Healthcare Products Regulatory agency (MHRA). We also welcome customer audits.
Only FlavorActiV GMP flavour standard capsules bear our mark of authenticity.
We brand each of our capsules so that our customers know they’re getting the Pharmaceutical GMP Quality that only FlavorActiV provide.
Industry leading packaging and shelf-life
FlavorActiV flavour standards are blister packaged, which extends shelf-life and protects capsules from potential contamination. The average shelf-life of FlavorActiV flavour standards is 18 months to 4 years, depending on the flavour compounds.
We will never ship in pots or plastic packaging, here’s why…
Blister packaging protects capsules from the environment until they are ready for use. Blister packaging greatly reduces the amount of headspace for possible flavour escape. As each capsule individually blister packaged, making use of one capsule still leaves all others protected. FlavorActiV Flavour Standard packaging is 100% recyclable, as opposed to polypropylene which is not widely recycled.
Pots are semi-porous, they allow molecules to pass through and flavour to be lost, their significant headspace also adds to substantial flavour escape as a gas, even when using just one capsule all those remaining in the pot are exposed.
