Problems solved by technology

The above-mentioned method for preparing seaweed polyphenols lacks the comprehensive utilization of main components such as alginate, and the waste of resources is serious; at the same time, the above-mentioned process technology for preparing seaweed polyphenols also has the following problems: 1) The separation effect is poor and the purity is low
Seaweed polyphenols are easy to form complexes with seaweed gum and protein in the form of non-covalent bonds, and it is difficult to separate them in the subsequent purification process, resulting in a low recovery rate of seaweed polyphenols; in addition, the extracted seaweed polyphenols also contain A large amount of fat-soluble pigments cannot be effectively separated by traditional column chromatography, resulting in low purity of the product
2) Large structural damage and low activity
Although microwave technology and ultrasonic-assisted extraction technology can improve the yield of marine polyphenols, the extraction process will generate high temperature, coupled with the lack of effective protection measures, the oxidation of marine polyphenols will be accelerated under the action of oxygen, resulting in the loss of activity
3) The production process is complicated and the cost is high
The current process for processing seaweed polyphenols includes multiple processes such as crushing, extraction, centrifugation, filtration, column loading, elution, resin regeneration, multiple concentration, and drying; conventional column chromatography purification of seaweed polyphenols must also be equipped with a constant flow Pumps, glass columns, collection devices and other equipment lead to long production time and high equipment requirements, which limit the development of industrialization
This is the key technical bottleneck leading to the industrial application of seaweed polyphenols

Description

technical field [0001] The invention relates to the technical field of seaweed polyphenols, in particular to a preparation method of high-purity seaweed polyphenols. Background technique [0002] Seaweed is the main source of marine plant polyphenols, and its structure is quite different from that of terrestrial plant polyphenols: terrestrial plant polyphenols are derived from gallic acid and halide acid; seaweed polyphenols are derivatives of phloroglucinol . Studies have shown that seaweed polyphenols have special effects in anti-oxidation, improving metabolic syndrome, and preventing degenerative diseases, and are safe and non-toxic. Therefore, European and American countries have invested heavily in the development and application of seaweed polyphenols. High-purity seaweed polyphenols have the advantages of strong biological activity, high medical value, and good stability, and are urgently needed products in the field of biomedicine. [0003] However, because seawee...
