Acetaldehyde Flavour Standard
The Acetaldehyde Flavour Standard is a sensory reference tool for professionals in the food and beverage industry to identify and evaluate the intensity of acetaldehyde, a naturally occurring compound in fermented products. Acetaldehyde imparts a distinctive aroma and flavour, often described as having a bruised apple flavour or green apple-like characteristics. In cider, this note can evolve to resemble emulsion paint at higher concentrations, while in beer, it adds complexity to the flavour profile. Still, excessive levels may indicate process flaws or storage issues.
Understanding and controlling acetaldehyde levels are essential for maintaining the desired bruised apple flavour and overall quality in fermented beverages. Whether you are a cider maker, brewer, or involved in the production of any fermented beverage, the Acetaldehyde Flavour Standard is indispensable in ensuring consistency and excellence in your product offerings.

Acetaldehyde’s sensory profile is often described as having a bruised apple flavour, reminiscent of green apples, or even evoking the smell of emulsion paint. This is a certified flavour standard used in professional sensory training, helping spirit tasters and brewers accurately identify and scale the intensity of acetaldehyde’s sensory character.
What is Acetaldehyde and Why Does it Matter?
Acetaldehyde is a volatile compound produced during yeast fermentation, often described as having a green apple-like aroma at low concentrations. As the concentration increases, acetaldehyde can develop a more prominent bruised apple flavour or even resemble emulsion paint, particularly in cider and beer.
While acetaldehyde is a natural component in fermentation, excessive levels can negatively impact the sensory profile of your product. Identifying and controlling acetaldehyde levels is crucial for maintaining product quality, flavour consistency, and consumer satisfaction.
The Acetaldehyde Flavour Standard enables sensory professionals to train their palate and accurately assess the intensity of this flavour, ensuring they can identify acetaldehyde levels accurately during production.

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.
