Certified flavour standards for foods and beverages


Capsules of reference flavour standards

Cara Technology Founder, Dr Bill Simpson, developed the world’s first stabilized flavour standards. For 17 years they’ve been used by taste panel leaders in more than 170 countries to improve the performance of their professional taste panels.


Certified flavour standards can be used to train your tasters to recognize and scale the intensity of more than 70 individual flavour notes in beer, cider, wine, water, soft drinks and a range of other foods and beverages including ready meals, spirits and oils. Each flavour standard contains a precise quantity of powdered sensory-pure flavour material, nano-encapsulated for stability.

Chemist analysing flavour materials in the manufacture of certified flavour standards

The materials are added directly to your product, be it beer, cider, wine, water, soft drinks or other foods or drinks.

Samples prepared in this way are then safe for tasters to smell and taste.

Each batch of flavour standards is extensively and meticulously analysed to assure consistent flavour character and strength.

Our flavour standards are produced and tested in accordance with our DS | EN | ISO 9001:2015 certified quality management system in facilities that conform to Pharma-GMP standards.

We make flavour standards for: beer, cider, soft drinks, water, wine

These certfied flavour standards are easy to use and require no specialist laboratory facilities. All you need is your product, clean bottles or flasks, some glasses and, of course, some tasters to taste the samples.

All AROXA certified flavour standards are provided with full instructions and are very easy to use. The concentration of each and every material is tailored to the product for which it's intended.

Thus a certified beer flavour standard for diacetyl (2,3-butanedione) is delivered at one concentration while that for wine is delivered at a different concentration.
