Comparison of Microwave-Assisted Extraction with Other Solid–Liquid Extraction Techniques - So sánh chiết vi sóng với một số kỹ thuật tách chiết Rắn - Lỏng khác
Comparison of Microwave-Assisted Extraction with Other Solid–Liquid Extraction Techniques To introduce bioactive plant extracts in pharmaceutical and cosmetic formulations, industries are looking for green and ef fi cient extraction processes free of toxic solvents. Methodologies using biodegradable and nontoxic solvents such as water and ethanol are being developed [ 52 ] . The traditional techniques of solvent extraction of plant materials are based on the correct choice of solvents and the use of heat or/and agitation to increase the solubility of the desired compounds and improve the mass transfer. Soxhlet extraction is the most common and is still used as a standard in all cases [ 53 ] . As a result of several secondary metabolites, the development of high performance and rapid extraction methods is an absolute necessity [ 54 ] . The new extraction techniques with shortened extraction time, reduced solvent consumption, increased pollution prevention...
