Extraction and stabilization of secoisolariciresinoldiglucoside (SDG) and other beneficial compoundsfrom flaxseed

摘要

A method is described for extracting secoisolariciresinol diglucoside (SDG) and otherbeneficial compounds from flaxseed which comprises contacting a substantially oil-free flaxseedmeal with an aliphatic alcohol solvent, e.g. a mixture of methanol or ethanol with water, to extractlignans into the alcohol solvent and separating residual solids from the lignan-rich alcohol solvent.The complexed phytoestrogens are then hydrolyzed with a base to provide uncomplexedphytoestrogens. The uncomplexed phytoestrogens are subsequently freeze dried and stabilizedwith a vegetable oil. The stabilized phytoestrogens can be formulated into products forconsumption.
