AI Technical Summary
Existing methods for extracting yam polysaccharides suffer from problems such as non-specific cell wall disruption, structural damage, low enzymatic hydrolysis efficiency, and unstable product quality, leading to loss of activity and limitations in industrial applications.
By employing electrochemical cell disruption combined with cryo-electrodialysis and immobilized enzyme membrane technology, and through separation by pulsed electric field and DC electric field, combined with lecithin nano-processing, selective cell disruption and efficient enrichment of yam polysaccharides are achieved.
It improves the activity retention rate and purity of polysaccharides, enhances bioavailability, and achieves the stability and efficient extraction of nanoscale products, making it suitable for health foods and medicines for the elderly.
