Abstract

An improved method for the extraction of galactans, and especially arabinogalactan, is provided which involves application of sonic energy to a mixture of galactan-containing starting material and extraction medium. Preferably, the method involves providing a mixture of Western larch chips and water, and subjecting this mixture to an acoustic or ultrasonic field for enhancing galactan recovery.
