Embodiment 1

[0016] A method for reducing the release of NNK in the flue gas of reconstituted tobacco leaves: before concentrating the extract of tobacco raw materials, adjust the pH value to 7 with NaOH solution, then add fructose by 0.1% of the weight of the extract, 0.01% of glycine was added.

Embodiment 2

[0018] A method for reducing the release of NNK in the flue gas of reconstituted tobacco leaves: before concentrating the extract of tobacco raw materials, adjust the pH value to 10 with NaOH solution, then add glucose by 3% of the weight of the extract, 1% added L-serine.

Embodiment 3

[0020] A method for reducing the release of NNK in the flue gas of reconstituted tobacco leaves: before concentrating the extract of tobacco raw materials, adjust the pH value to 8 with NaOH solution, then add maltose by 0.5% of the weight of the extract, Add 0.1% of L-valine.

Abstract

The invention discloses a method for lowering release amount of NNK (nicotine-derived nitrosamine ketone) in reconstituted tobacco. The method includes: adjusting pH of extract of tobacco material, and adding reducing sugar and amino acid in the extract. Process conditions in extract concentration during production of the reconstituted tobacco are fully utilized. Alkaloid is converted to be free by Maillard reaction. Therefore, precursor substances of harmful NNK in the smoke of the reconstituted tobacco are reduced, and the release amount of NNK in the smoke of the reconstituted tobacco is lowered. The method has the advantages that operation is simple, and additional energy consumption is not needed.

Description

technical field [0001] The invention belongs to the technical field of production and processing of reconstituted tobacco leaves, and in particular relates to a method for reducing the amount of NNK released in smoke of reconstituted tobacco leaves. Background technique [0002] 4-(Methylnitrosamine)-1-(3-pyridyl)-1-butanone (NNK for short) is a kind of nitrosamines (TSNAs for short) in tobacco smoke, mainly derived from amino acids and The decomposition product of protein during combustion has carcinogenic effect. R.J. Reynolds Company of the United States uses the technology of curing tobacco leaves to reduce the content of TSNAs in flue-cured tobacco. Domestic Dai Ya and others use the method of adding hemoglobin in the mouth stick to remove NO, NOx, and carcinogenic nitroso compounds in the flue gas. . [0003] Maillard reaction, also known as "non-enzymatic browning reaction", was proposed by French chemist L.C.Maillard in 1912. It is a reaction between carbonyl comp...
