Example Embodiment
[0032] Example 1
[0033] Extraction of kelp dietary fiber: add calcium chloride solution to the turbid glue solution of kelp residue until all the kelp residue is flocculated, collect the flocs by standing, add distilled water to the flocs, add hydrochloric acid solution to decalcify, and then collect by centrifugation, Repeat the above decalcification step once, add an appropriate amount of sodium carbonate solution to the filtrate to neutrality, collect the filtrate, add sodium hypochlorite with a mass concentration of 10% in the solution to bleach for 24 hours, suction filtration, wash with water, and then rinse with 75wt% ethanol. Suction filtration, vacuum freeze-drying at 50°C, and pulverization to obtain kelp dietary fiber.
[0034] Preparation of soluble kelp cellulose: add 2wt% NaOH solution to the kelp dietary fiber obtained in step (1) at a mass ratio of 1:20, soak at room temperature for 48h, wash with water until neutral, and add water at a ratio of 1:20 , steam...
