Rapid solid-liquid dynamic extraction (RSLDE): A powerful and greener alternative to the latest solid-liquid extraction techniques

Traditional methods like Soxhlet extraction have long relied on harsh solvents and grueling procedures to pull valuable compounds from solid materials. What if we could capture active ingredients faster, at room temperature, and without degrading them?

Extracting colorants, bioactives, and aromatic substances from plants and food waste has traditionally meant turning to lengthy atmospheric pressure systems like maceration or percolation. But as environmental awareness and the demand for greener chemistry grow, the scientific community is shifting toward sustainable, non-conventional processes that save time, cut energy use, and minimize waste.

Enter rapid solid-liquid dynamic extraction, or RSLDE. Performed using the Naviglio extractor and driven by Naviglio’s principle, this innovative technique turns traditional extraction on its head. It slashes extraction times and boosts yields without requiring any system heating at all.

By avoiding thermal degradation, RSLDE safely preserves delicate active ingredients. This review spans the past two decades of research, exploring how RSLDE has transformed extraction across various scientific and production sectors.

Key Points

• Reduces extraction times and solvent consumption
• Operates without requiring system heating
• Prevents degradation of active ingredients
