| titleOfInvention | A kind of extraction and concentration method of tobacco water extract |
| abstract | The invention discloses a method for extracting and concentrating tobacco water extract, belonging to the technical field of extraction and concentration of tobacco extract. The invention includes the following steps: Step 1: mixing tobacco raw material with water, and putting into the mixed solution for oxidation Graphene, the overall mixture formed by tobacco raw material, water and graphene oxide is subjected to secondary water bath heat extraction, and after extraction, the tobacco water extract is extruded by extrusion to obtain a tobacco extract with a solid content of 3-10%; Step 2: filtration and purification, the tobacco extract obtained in step 1 is filtered twice to obtain a clarified filtrate for use; step 3: forward osmosis concentration, the clarified filtrate of step 2 is subjected to forward osmosis concentration, and salt is used as a drawing agent, Using at least 2 stages of concentration to concentrate to a tobacco extract solid content of 50-60% to obtain a tobacco water extract concentrate. The water extract extracted by the method has more abundant aroma substances, and the amount of the extracted substance is small, the recycling rate is improved, and the cost is reduced. |
