natural extraction through scent evaporation, as nature intended.
Evaporative Extraction™ uses high velocity heated air to evaporate volatile aromatics from French and American oak barrels to produce intensely aromatic extracts that are a perfect copy of the original aroma source.
It is important to understand how your nose really works…
Everything we smell can be attributed to the evaporation of volatile aromatic compounds into the air we breathe.
When we smell a rose, we are not actually smelling the rose – we are smelling volatile aromatic molecules that evaporated from the rose. No part of the rose is entering our nose.
The same goes for smelling a glass of whiskey. We are not smelling the whiskey – we are smelling volatile whiskey aromatics that evaporated into the air above our glass.
While this may seem obvious, it is an important and mostly overlooked distinction that makes all the difference when engineering a method of extraction.
Evaporative Extraction is the only technology that leverages the same fundamental scent evaporation principals that allow us to smell the world around us.
When volatile aromatics evaporate from an aroma source, they enter the air in specific relative proportions. These relative proportions are the true representation of the original aroma source – the signature – and are the only way that our noses can identify an aroma source.
Based on this fundamental understanding, one would conclude that the best way to extract aromatics should involve evaporation, but surprisingly – conventional extraction methods do not leverage evaporation.
“In the last 50 years, only two fundamentally new extraction technologies have been invented - CO2 extraction and Evaporative Extraction.”
- Bob Weinstein, President of Robertet Ingredients.
Superior extraction of micro aromatics is the key to perfect replication of the original aroma source.
True to its name, Evaporative Extraction leverages evaporation to capture aromatics from source materials in the same relative proportions as what would naturally enter your nose from smelling the actual source material. Evaporative Extraction provides the most sensorially-accurate, and complete aromatic profile possible.
Conventional methods of extraction employ various solvents ranging from water to hydrocarbons or use supercritical CO2 or steam distillation. All such methods result in disproportionate replication of the original aromatics that evaporate from the source material.
evaporative extraction
Evaporated extracts are vibrant. When lab tested, hundreds of aromatic components are found to be present. Evaporated extracts capture aromatics in the same, specific relative proportions as found in the original aroma source.
conventional extraction
Conventional extracts are mono-dimensional and lack complex aromatics. When lab tested, only primary components are present. Conventional extracts contain aromatic ratios that are out of proportion with the original aroma source.
Evaporative Extraction not only provides accurate replication of source aromas - it recovers more desirable volatile aromatics than than barrel aging.
WHY IT’S BETTER:
Evaporative Extraction reaches much deeper into the wood than the beer, wine, or spirits that are being oak aged
Evaporative extraction provides superior recovery of hard-to-extract volatile micro aromatic compounds from deep within the aromatic wood source.
Evaporating volatile compounds are driven out of the wood as expanding gasses. Other methods of extraction cannot achieve this, nor can the actual barrel aging process.
Evaporative Extraction uses air instead of solvents.
How it Works
Evaporative Extraction uses high-velocity heated air to evaporate volatile aromatics from woods and plants - and then rapidly absorbs and captures the evaporated compounds from the air to produce highly-aromatic flavor and beverage infusion ingredients.
Source material is continuously fed into one end of the machine while captured aromatics and depleted material continuously exits the other. This enables high production output while exposing the source material to processing for only a couple of seconds.
(1) A pressure blower circulates high-velocity air throughout the system. (2) The air passes through a heater and is heated to an ideal temperature to promote rapid evaporation. (3) Wood or plant source material is metered into the air stream. (4) The source material is pneumatically suspended within a series of highly turbulent evaporation columns. Volatile aromatic compounds evaporate within seconds. (5) Depleted source material is centrifugally separated from the air stream. (6) Volatile aromatic compounds are condensed and separated from the air stream using a proprietary, dynamic collection method. (7) The captured aromatic compounds are collected in a finished product reservoir.
Proven, exclusive technology. 68 granted and pending international patents.
Evaporative extraction is proprietary to Aroma Sciences. The technology has been used to produce extracts from more than 110,000 pounds of premium herbal products, including oak, sandalwood, vanilla, hops, orris root, cardamom, basil, nutmeg, bay leaves, and dozens of other pods, seeds, rhizomes, and woods. It has been shown to excel with the extraction of hard-to-reach volatile components that are typically locked deep within plant material and not easily liberated by solvents.
