AI Technical Summary
Existing technologies for extracting fucoidan from kelp suffer from problems such as high extraction temperature, long extraction time, high energy consumption, and easy breakage of polysaccharide molecular chains, making it difficult to achieve efficient, energy-saving, and environmentally friendly extraction.
A three-stage treatment process combining steam explosion technology with acid soaking and compound enzymatic hydrolysis was adopted. Through the synergistic effect of physical cell wall disruption, chemical softening and biodegradation, the steam explosion parameters and enzymatic hydrolysis conditions were optimized to achieve efficient deconstruction of kelp cell walls.
It significantly improves polysaccharide yield, protects the molecular integrity and bioactivity of polysaccharides, has high extraction efficiency, short extraction time, and requires no organic solvents, making it suitable for the pharmaceutical and functional food industries.
