Abstract: A preparation method for a diet-reducing capsule containing multi-nutrient microspheres and a resulting product, relating to the field of food biotechnology, are provided. The diet-reducing capsule includes a porous capsule shell, multi-nutrient microspheres and a matrix gel containing the multi-nutrient microspheres. The porous capsule shell is prepared by using a laser punching technology. The multi-nutrient microsphere is a miniature container which is formed by taking probiotics as a core material and taking a freeze-drying protective agent, a natural polymer material embedded with vitamins, minerals and prebiotics and an enteric coating material as a wall material. The matrix gel for the microspheres is biomimetic cellulose superabsorbent gel.

Abstract: A method for preparing a degradable drug-loaded microsphere for embolization and a product obtained therefrom, includes the steps of: dissolving a degradable material in an organic solvent, then adding a drug and mixing well to form a suspension or solution; then pouring the drug-containing suspension or solution into an aqueous solution of polyvinyl alcohol, stirring, and thereafter adding water twice for dilution, to prepare the degradable drug-loaded microsphere. The microsphere prepared by the present invention has the advantages of having a controllable particle size, a high drug loading capacity, and a regular spherical shape, being convenient for sieve sizing and accurate particle-size indication, and being accurately targeted to an embolized blood vessel, and the like, and thus has a good application prospect in interventional embolization therapy.
