Abstract

The invention relates to a an extraction method of a flaxseed extract, which is suitable for the technical field of flaxseed extraction. The extraction method of the flaxseed extract comprises the following steps: flaxseeds are separated to obtain flaxseed kernels and flaxseed skins; a kernel cake obtained by pressing oil from flaxseed kernels with purified water, after properly adjusting the pH value, water bath heating oscillation is carried out, freeze-drying and crushing are carried out on a solid phase obtained after centrifugation to obtain flax protein isolate; the flaxseed skin is putinto boiling water to be stirred; the obtained liquid is concentrated to obtain flax gum liquid, which is used for extracting lignan from flaxseed gum liquid by using edible alcohol and precipitatingflaxseed gum, the flaxseed gum and alcohol containing lignan are obtained; according to the present invention, the alcohol is recovered by an alcohol recovery tower to obtain a lignan-containing solution, which is best used for organic solvent extraction of lignan solution to obtain linseed oil. According to the extraction method, the linseed extractable substance can be completely extracted, thematerial utilization efficiency is high, the extractable substance is rich, and the subsequent processing and the production of a variety of products are easily performed.

Description

technical field [0001] The invention belongs to the technical field of flaxseed extraction, in particular to a method for extracting flaxseed extract. Background technique [0002] In addition to rich linolenic acid, flaxseed also contains about 10% flax glue, about 19% protein, about 1% lignan, and about 28% dietary fiber. These nutrients and active ingredients are high in content and types It is unmatched by other plants. Because flaxseed is a treasure from the inside out, it is called "the functional food of the 21st century". However, due to technical bottlenecks, the comprehensive development and utilization of flax nutritional active ingredients are limited, which affects the development of flax industry. [0003] Studies have shown that from the relationship between the morphological structure of flaxseed and various nutritional components and bioactive components, they exist in the kernel and hull of flaxseed respectively: fat and protein are mainly distributed in ...
