Raspberry Ketone: FEMA Status and Solubility
Question
What does the FEMA 2588 code indicate about Raspberry Ketone's suitability as a food flavoring/food grade, and what solvents are suitable for dissolving this substance, given its poor solubility in oils?
Answer
Raspberry Ketone (FEMA-2588)
Regarding your questions about Raspberry Ketone (FEMA-2588):
FEMA 2588 Code and Food Grade: The FEMA number (like FEMA 2588) is assigned by the Flavor and Extract Manufacturers Association in the U.S. It indicates that the substance is considered Generally Recognized As Safe (GRAS) for use as a flavoring ingredient when used according to good manufacturing practices. This means it is approved for use in food flavorings. However, the specific "food grade" certification of the product you purchased would depend on the supplier's specific quality control and certifications. While the FEMA status indicates its suitability for flavoring, we cannot confirm the specific grade of your product without its detailed specifications.
Solubility: Raspberry Ketone is a polar compound. It is generally soluble in polar organic solvents such as ethanol (alcohol) and propylene glycol. It has limited solubility in water and is poorly soluble in non-polar oils like olive oil or sesame oil, which aligns with your observation that it did not dissolve in oil. Therefore, to dissolve Raspberry Ketone, you should use solvents like ethanol or propylene glycol. Specific preparation methods regarding temperature or mixing time are not available in the product information, but typically dissolution in suitable solvents is done at room temperature with stirring until clear.
In summary, FEMA 2588 confirms its use as a flavoring agent and GRAS status for that purpose. It is soluble in polar solvents like alcohol and propylene glycol, but not well in oils.
