Embodiment 1
[0031] The extracting method of palm ginseng polysaccharide comprises the following steps:
[0032] S1, take palm ginseng, after coarse powder, pass through a 20-mesh sieve to obtain palm ginseng powder;
[0033] S2. Add 4 times the weight of sodium bicarbonate and sodium sulfite mixed solution to the palm ginseng powder, soak for 1 hour at room temperature, and centrifugally filter to make the water content of the filter cake 45-50%, to obtain the first filter cake;
[0034] S3. Dispersing the first filter cake, placing it in a steam explosion tank, and performing superheated steam spray explosion treatment in a moving state to obtain steam explosion materials;
[0035] S4. Add water of 20 times the weight of the palm ginseng powder to the steam explosion, extract at room temperature for 40 minutes, and centrifugally filter to make the water content of the filter cake less than 20%, and take the filtrate to obtain water Extract;
[0036] S5. Concentrating the water extract ...
