Problems solved by technology

This method has shortened extraction time compared with traditional method, and the yield of fucoxanthin has also been improved, but dimethyl sulfoxide is used as extraction solvent, when carrying out liquid-liquid extraction with ethyl acetate and ammonium sulfate, There are residues in the ethyl acetate phase, and dimethyl sulfoxide has a high boiling point, which cannot be removed by low-temperature vacuum distillation, so that the sample cannot be dried, and its existence will affect the subsequent purification of fucoxanthin; and In this patent application, the obtained concentrate needs to be repeatedly purified by silica gel column to obtain a high-content fucoxanthin product, which causes a large amount of adsorption loss of the target substance and increases the complexity of the process. It helps to simplify the production process by removing part of the impurities at one time
[0007] However, due to the special physiological structure of Phaeophyceae seaweed, the extraction of fucoxanthin from it has always had problems such as low extraction efficiency and a large amount of organic solvents, which not only caused a waste of resources, but also had a great impact due to the residue of organic solvents. product quality
In view of the above-mentioned defects, it cannot meet the needs of actual production

Abstract

The invention relates to a method for extracting a fucoxanthine-containing concentrate from algae, the fucoxanthine-containing concentrate obtained through the method, and application of the fucoxanthine-containing concentrate. The method comprises the following steps of: pretreating raw materials; performing enzyme treatment; extracting; separating; concentrating and the like. The method overcomes technical defects of low efficiency of extracting fucoxanthine and high consumption of an organic solvent in the prior art, and a fucoxanthine product with high active ingredients is obtained, so the fucoxanthine product has a good application prospect. The raw materials are readily available, the extraction process is simple, and the obtained product has stable content and controllable comprehensive cost, and is suitable for industrial production and lengthening an industrial chain.

Description

【Technical field】 [0001] The invention belongs to the technical field of extracting active ingredients from natural plants. More specifically, the present invention relates to a method for extracting a concentrate containing fucoxanthin from seaweed, and to the concentrate containing fucoxanthin obtained by the above method, and to the concentrate containing fucoxanthin Concentrate use. 【Background technique】 [0002] Seaweeds that grow in the ocean, especially organisms of the Phaeophyta family (including Laminaria japonica, Sargassum fusiforme, Sargassum, Macrocystis pyrifera (L.) Ag), wakame Vegetables (Undaria pinnatifida), asparagus (Gracilaria sp), etc.) are rich in carotenoid compounds, among which fucoxanthin has the highest proportion, which is an ideal natural resource for extracting fucoxanthin. [0003] Fucoxanthin, also known as fucoxanthin, the English name is Fucoxanthin, molecular formula C 42 h 58 o 6 , is a rare oxygen-containing carotenoid existing in...
