Optimization of Supercritical CO2 Extraction of Allicin from Garlic Cloves

doi:10.7506/spkx1002-6630-200916026

Abstract

Abstract:

We optimized the supercritical CO2 extraction of allcin from garlic cloves to obtain the highest extraction yield by single-factor and orthogonal array methods. The optimal conditions for the improved supercritical CO2 extraction of allicin were determined as follows: extraction press 15 MPa, extraction temperature 40 ℃, static extraction time 30 min and dynamic extraction time 105 min. Under these conditions, the extraction yield could reach 76.70%, which was higher than 63.16% by traditional solvent extraction and 68.12% by ultrasonic-assisted extraction.

Key words: supercritical CO2 extraction, garlic, allicin, extraction yield
