Abstract
Disclosed in the present disclosure is a method for extracting and separating various components from flaxseed meal based on a subcritical composite solvent, including the following steps: adding an extraction agent to flaxseed meal for subcritical extraction to obtain a crude flax lignan extract and crude flaxseed oil in one step, where the extraction agent includes n-butane and anhydrous ethanol at a volume ratio of 1:1; adding n-hexane to the crude flaxseed oil for fractional extraction, and conducting rotary evaporation to obtain flaxseed oil; and subjecting the flaxseed meal used to hot water extraction to obtain flaxseed gum. In the present disclosure, the subcritical composite solvent used in an extraction process can replace a large number of organic reagents used in a traditional extraction process, and has the characteristics of good solvent effect, environmental friendliness, recyclability, and low burden on the environment.
