Classification of Raspberry Ketone (FEMA 2588): Natural vs. Nature-Identical Flavor

Raspberry Ketone (FEMA-2588, CAS 5471-51-2) is a key aromatic compound found naturally in raspberries. However, the classification of a commercial product as a "natural flavour" depends entirely on its method of production and the regulatory standards of the region where it is used.

Here is a breakdown of the typical classifications:

1. Natural Raspberry Ketone: This is extracted directly from raspberries or other natural sources. Due to the high cost and low yield of extraction, this is rare and expensive.
2. Nature-Identical Raspberry Ketone: This is the most common form. It is chemically synthesized to be identical to the molecule found in nature. In many jurisdictions (including the EU and often in the US), this synthetic version is not classified as a "natural flavour." It is typically labeled as an "artificial flavour" or "nature-identical flavouring substance."
3. Natural Flavoring Substance (Produced by Fermentation/Biotechnology): Raspberry Ketone can also be produced through biotechnology (e.g., fermentation using yeast or bacteria). If the starting materials and process meet specific regulatory criteria, this version may be classified as a "natural flavouring substance" in some regions, even though it is not extracted from raspberries.

Conclusion for the product listed:

The product "Raspberry Ketone (FEMA-2588)" with CAS 5471-51-2 is a single chemical substance. Without knowing the specific manufacturing process (extraction vs. synthesis vs. biotechnology), it is impossible to definitively label it as "natural."

• If it is chemically synthesized (most likely): It is generally not considered a natural flavour.
• If it is extracted from raspberries: It is considered a natural flavour.
• If it is produced via biotechnology/fermentation: It may be considered a natural flavour, depending on local regulations.

For regulatory compliance, you must confirm the manufacturing method and consult the specific food and flavour regulations for the country where the product will be sold.
