AI Technical Summary
Existing technologies for separating polysaccharides from edible fungi suffer from problems such as low efficiency of simultaneous multi-component fractionation, low purity, and inaccurate membrane fouling control, resulting in poor product purity and recovery rate, and failing to achieve efficient co-production of polysaccharides, oligosaccharides, and monosaccharides in the same process flow.
By employing multi-stage gradient membrane separation and precision concentration integration technology, and utilizing the synergistic cooperation of membrane modules with different retention characteristics, combined with specific hydrodynamic control parameters and physicochemical cleaning strategies, a multi-component membrane separation process for edible fungal sugars is constructed. This process includes microfiltration, two-stage ultrafiltration, and reverse osmosis, achieving refined separation of sugar components with different molecular weight ranges through precise control.
It achieves high-purity acquisition of polysaccharides, oligosaccharides and monosaccharides from edible fungi, improves the bioactivity and separation rate of the products, reduces operating costs, and significantly improves process stability and purity, making it suitable for the high-value utilization of various edible fungi.
