Transferring of Key Chemical Components in Paper-making Process Reconstituted Tobacco Sheet

PurposeOur aim was to investigate the transferring of key chemical components (total sugar, potassium, sugar, nicotine, chlorine and total nitrogen) in paper-making reconstituted tobacco sheet at various processing stages.MethodWe analyzed the contents of key chemical components in the solids with continuous flow analytical method.Results(1) Except total nitrogen, every key chemical component had a higher extraction rate at extraction stage. The extraction rate of the total key chemical components was 80.37%, that is, 80.37% of the key chemical components were transferred from tobacco raw materials to water. (2) In the pulping stage, the content of key chemical components were lower. 11.02%, 16.61%, 11.00%, 17.31%, 10.43% and 25.84% of the total sugar, potassium, reducing sugar, total alkaloids, chloride and total nitrogen in tobacco raw materials was extracted into the sewage.ConclusionTherefore, optimizing the extraction process, and reducing the extraction yield of each key chemical component in pulping section can improve the competitiveness of designed paper-making reconstituted tobacco sheet.
