Embodiment

[0053] A subcritical composite solvent extraction and separation method for various components of linseed meal comprises the following steps:

[0054] (1) Weigh 10.0g of ground flaxseed meal powder and place it in the extraction bag in the subcritical extraction kettle, add 200mL of n-butane, conduct a single factor test of extraction conditions, explore different composite solvents (n-butane and absolute ethanol) ratio ( figure 2 ), extraction temperature ( image 3 ), extraction time ( Figure 4 ) on the total phenol content, according to the results of the single factor optimal value, the response surface design experiment was carried out, and the optimal conditions of subcritical extraction were obtained as the composite solvent ratio of 1:1 (n-butane and absolute ethanol), and the extraction temperature was 69°C , the extraction time was 2h, and the total phenol content of the obtained sample was 22.76mg GAE / g.

[0055] After extraction, the upper layer of the extract...

Abstract

The invention discloses a subcritical composite solvent extraction separation method for multiple components in flaxseed meal. The method comprises the following steps: taking flaxseed meal, adding an extraction agent, and carrying out subcritical extraction to obtain a crude flax lignan extract and crude flaxseed oil in one step, wherein the extraction agent is composed of n-butane and absolute ethyl alcohol according to the volume ratio of 1: 1; adding n-hexane into the crude flaxseed oil, performing liquid separation extraction, and carrying out rotary evaporation to obtain flaxseed oil; and extracting the taken flaxseed meal with hot water to obtain flaxseed gum. The subcritical composite solvent used in the extraction process can replace a large amount of organic reagents used in traditional extraction, has the characteristics of good solvent effect, greenness, recyclability, small environmental burden and the like, and can reduce the risk of the organic reagents to operators and the natural environment in the process. And the subcritical extraction has lower requirements on operation and professionals, various high-added-value components are obtained while operation units are reduced, the resource utilization is maximized, and the cost is reduced, and the benefit is increased.

Description

technical field [0001] The invention belongs to the field of extraction and separation of plant effective components, and in particular relates to a subcritical composite solvent extraction and separation method for various active components in linseed meal. Background technique [0002] Flaxseed oil is rich in α-linolenic acid, V E and other nutrients. The flaxseed cake obtained after pressing still contains residual oil, as well as active ingredients such as lignans, polysaccharides (gums) and proteins. As the main by-product of linseed oil processing, linseed meal is usually only used as animal feed, fertilizer or waste disposal, and the resource is underutilized. [0003] At present, flaxseed products in my country are mainly flaxseed oil, which is single and homogeneous, and the development of flaxseed functional food ingredients has gradually become a hot spot. Oils and fats can be extracted by pressing, solvent extraction and supercritical CO 2 Extraction method, ...
