Study on green extraction of limonene from orange peel and cascade catalysis to produce carvol and carvone in deep eutectic solvents

What if the secret to greener chemistry is hiding in your fruit bowl? Orange peels, often discarded, are now the starting point for a sustainable transformation into valuable aroma compounds.

The study explores a green extraction method for limonene from orange peel using deep eutectic solvents (DES), a class of eco-friendly solvents. Limonene, a major component of orange peel oil, is a valuable compound with applications in fragrances and flavors. The researchers aimed to optimize the extraction process and then convert limonene into carvol and carvone, which are also important aroma compounds, through cascade catalysis in the same DES medium. This approach aligns with the principles of green chemistry by reducing hazardous waste and improving sustainability. The abstract details the extraction and catalysis steps, emphasizing the potential of DES as a versatile medium for both processes.

Key Points

• Green extraction of limonene from orange peel using DES.
• Cascade catalysis converts limonene to carvol and carvone.
• DES serves as eco-friendly medium for both steps.
