| description | The invention discloses an extraction and concentration method of a tobacco aqueous extract and belongs to the technical field of extraction and concentration of a tobacco extracting solution. The extraction and concentration method comprises the following steps of step 1, mixing a tobacco raw material with water, adding graphene oxide into the mixed solution, and performing secondary water bath hot extraction on an integral mixture formed by the tobacco raw material, the water and the graphene oxide to obtain a tobacco aqueous extract; after extraction, the tobacco aqueous extract being extruded in an extrusion mode, and a tobacco extracting solution with the solid content being 3-10% being obtained; 2, filtering and purifying, namely filtering the tobacco extracting solution obtained in the step 1 twice to obtain clear filtrate for later use; and 3, forward osmosis concentration, performing forward osmosis concentration on the clarified filtrate obtained in the step 2, and concentrating the clarified filtra |
