| titleOfInvention | A kind of food silica anticaking agent and its preparation method and application |
| abstract | The invention belongs to the technical field of silicon dioxide, and in particular relates to a silicon dioxide anticaking agent for food and a preparation method thereof. The present invention includes the following steps: S1, taking water glass to dissolve in water, adding water to dilute it after aging to prepare a water glass solution, and configuring a sulfuric acid solution with a concentration of 1.0-3.0 mol/L, for use; S2, adding water to the reaction tank, heating, Start stirring; S3, add oxalic acid aqueous solution to the reaction tank under stirring, then add sulfuric acid solution and water glass solution simultaneously, add sodium hydroxide aqueous solution, then add sulfuric acid solution, age and stir; S4, will form the silica Perform filter-press washing treatment, spray-drying and crushing, and control particle size. The invention has the advantages of low cost, simple method, stable process and easy industrialization implementation. The silica prepared by the method of the invention has large porosity and specific surface area, and can be used as an anti-caking agent in the food industry. |
