Coffee Absolute: Nature, Price, and Sediment in Fragrance
Question
What is Coffee Absolute, how does it differ from typical coffee extract, why is it more expensive, and will the black sediment observed in a fragrance formula dissolve?
Answer
Coffee Absolute: Nature, Price, and Sediment
What is a Coffee Absolute?
A coffee absolute is a highly concentrated aromatic extract obtained from coffee beans (usually Coffea arabica) using solvent extraction methods. This process is different from making essential oils (which are typically steam distilled) or simple extracts. Absolutes capture a broader range of aromatic compounds, including heavier, non-volatile ones, resulting in a rich, complex aroma closer to the natural source.Is it the same as typical coffee extract?
No, a coffee absolute is generally not the same as a typical coffee extract you might find for food flavoring or simple cosmetic use. "Typical" extracts can be made using various solvents (like water, alcohol, or glycerin) and methods, often resulting in a less concentrated or different profile than an absolute specifically prepared for perfumery or high-end cosmetics. The term "absolute" refers to a specific type of highly concentrated extract obtained through a multi-step solvent extraction process.Why is the price higher?
Absolutes are typically more expensive than other types of extracts or essential oils for several reasons:- Concentration: They are very concentrated, meaning a large amount of raw material is needed to produce a small quantity of absolute.
- Complex Process: The solvent extraction process is more involved and requires specialized equipment and expertise compared to simpler extraction methods.
- Yield: The yield of absolute from the raw plant material can be relatively low.
Will the black sediment dissolve?
It is common for natural absolutes, including coffee absolute, to contain natural plant waxes, resins, pigments, and other non-volatile compounds that are extracted along with the aroma molecules. These components can sometimes appear as sediment, especially if the absolute is stored at cooler temperatures or mixed into a solvent like alcohol (common in fragrance formulas) where they are less soluble.- This sediment is often a natural part of the product and doesn't necessarily indicate poor quality.
- It may not fully dissolve in your fragrance formula, particularly in alcohol.
- Warming the mixture gently (using a warm water bath) might help some of the sediment dissolve.
- If the sediment is undesirable, you may need to filter the final fragrance mixture after allowing it to sit for a period to let the sediment settle.
In summary, a coffee absolute is a specific, highly concentrated type of extract. Its price reflects its concentration and the extraction process. The presence of sediment is often natural and may require specific handling like warming or filtration in your formulation.
