Seaweed Extract Preparation
There are also many methods for preparing seaweed extracts products. At present, there are three main methods for digesting seaweed bodies internationally: physical methods, chemical methods, and biological methods. Enzymatic hydrolysis or physical digestion can retain the activity of natural seaweed substances to the greatest extent, but they are technically difficult and require high equipment. The second is the fermentation of seaweed by microorganisms.
The process conditions are relatively mild, which can retain the active ingredients of seaweed to a large extent. While retaining the active ingredients of seaweed, it converts its macromolecules into small molecules that can be directly absorbed by crops, and can also metabolize and produce other active ingredients that are not contained in seaweed raw materials and are beneficial to crops. Process. Some production companies also use chemical extraction methods, using acids, alkalis and oxidants to digest seaweed, which is easy to industrialize in batches and can improve the efficiency of algae processing and extraction, but it also causes a certain degree of damage to the active substances in seaweed.
