Description
Technical field
The invention belongs to the technical fields of cigarette filter drop evil, and in particular to amino acid glyceride selectivity reducing cigarette cigarette
The purposes of phenol in gas further relates to a kind of method for reducing phenol release amount in cigarette smoke, further relates to one kind and contain amino acid
Cigarette filter of glyceride and preparation method thereof.
Background technique
As releasing content of coke tar in cigarette reduces year by year, simple tar reduction technology is no longer satisfied cigarette industry technology and needs
It asks.While releasing content of coke tar in cigarette reduces, often with the loss of aroma component in flue gas, to reduce cigarette smoking product
Matter.Therefore, since State Tobacco Monopoly Bureau in 2010 starts " lowering harm and decreasing coking " key special subjects, the technology of entire cigarette industry is ground
Study carefully center of gravity to be gradually transferred to " lowering harm and decreasing coking " by " reducing tar and reducing harm " technology, more attention is the exploitation of selective harm-reducing technology.
Cigarette filter can be retained, adsorb, remove or be diluted and come from leaf group as an important component of cigarette
The harmful components in cigarette mainstream flue gas are effectively reduced in the main flume at end, become each cigarette enterprise at present and realize " harm reduction drop
The effective way of coke " and the breach of each interprise's intensive management.
Yunnan Inst. of Tobacco Sciences apply red woods etc. invented it is a kind of by the inorganic fibers such as quartz sand, lime stone pass through
Crush, melt, reeling off raw silk from cocoons, soften after be prepared into particle, after applying in filter tip, can significantly reduce the phenol in cigarette smoke.
Mao Youan of Hunan Zhongyan industry Co., Ltd etc. is by p- [1- (4- the hydroxy phenyl) -1- methyl second of deep cavity shape
Base] cup [8] aromatic compound as composite tip stick additive, can reduce BaP and phenol in flue gas simultaneously.
It has invented using porous material as carrier and in porous material in storage state sea of China Tobacco Industry Zhejiang Co., Ltd. etc.
On in a manner of LBL self-assembly alternate load polyanion and hydrophily polycation a kind of polyacrylate and amino glucose
Ester composite material can reduce phenol type substances in flue gas after being added to cigarette filter.
These above-mentioned researchs only from the point of view of reducing phenol, are not accounted for and are taken out when reducing phenol to tar and cigarette
Inhale the influence of organoleptic quality.Inventor, not only can be with it was surprisingly found that using glycine glyceride as additives of filter tip
The phenol release amount of selectivity reduced in cigarette mainstream flue gas, can also reduce the influence to coke tar in cigarette to greatest extent, and
To the organoleptic quality of cigarette itself without negative effect.
