Embodiment 1

[0023] 1) Preparation includes:

[0024] Dissolve 10 g of heme derived from commercial or animal blood extracts in acetic acid solution (100 ml) of 33% hydrobromic acid, stir at room temperature for 48 hours, then slowly add methanol, reflux for 2 hours, and concentrate under reduced pressure to remove the solvent. The residue was then suspended in water, the pH was adjusted to 8 with 2N aqueous sodium hydroxide solution, and the solid was collected by filtration. Dissolve the dried solid in methanol solution of 1N sodium hydroxide, reflux for 30 minutes, concentrate the methanol solution to dryness, dissolve the obtained solid in water, adjust the pH to 3~5 with acetic acid solution, collect the solid, and separate Required filter additives (R 1 =R 2 =CH 3 ),

Abstract

The invention discloses filter additive for reducing nitrosamines in cigarette smoke and application of the filter additive. The filter additive is one of protoporphyrin derivatives. The filter additive with 0.05-10% of carrier weight is suspended in solvent and is sprayed to a carrier, and the carrier with the added protoporphyrin derivative is added to a stranded filter stick in strand forming to make the compound filter. The filter additive has the advantages that the protoporphyrin derivative is provided initially and has an evident effect in lowering content of TSNAs (nitrosamines) in smoke.

Description

technical field [0001] The invention belongs to the field of cigarette manufacture, and in particular relates to a cigarette filter additive with harm reduction and its application, especially a filter additive for reducing nitrosamines in cigarette smoke and its application. Background technique [0002] In 1990, D.Hoffmann and S.S.Hecht published a list of 12 types of 43 harmful components in smoke. Then, the analysis and reduction of the special harmful components of cigarette smoke gradually become the focus of tobacco scientific research (D.Hoffmann, I.Hoffmann, K.EI-Bayoumy, Chem.Res.Toxicol., 2001, 14 (7), 767-790 ). Chinese researchers (Xie Jianping, Liu Huimin, Zhu Maoxiang, etc., Tobacco Science and Technology, 2009 (2), 5-15) analyzed and evaluated 163 cigarette samples from the Chinese market, and analyzed 29 kinds of harmful components in cigarette mainstream smoke (including 4 kinds of TSNAs, 3 kinds of PAHs, 8 kinds of carbonyl compounds, 7 kinds of phenolic...
