Abstract

A tobacco smoke filter or filter element comprising: a tobacco smoke filtering material including paper; and a flavour enhancing additive.

Description

Tobacco smoke filter
The present invention relates to tobacco smoke filter (for example being used for cigarette) and manufacturing thereof.
Worldwide, cellulose acetate is the main material that uses in the tobacco smoke filter.Also known use paper for example is used for cigarette as the filter material in the filter tip; Paper is providing the many advantages that are superior to cellulose acetate in the biodegradability that improves aspect more filtration efficiency under the constant pressure drop and lower material cost.Although these advantages are arranged, the filter-tip application of paper is little and be limited to microhabitat (niche) purposes usually.The paper filter tip does not cause that the main cause of general market interest is that they have adverse effect to the taste of cigarette.This so-called " paper flavor " often is considered to give smoke from cigarette more puckery more dried sensation.
Therefore hope very much to overcome this " paper flavor " and produce the smoking sensation from the paper filter cigarette suitable with conventional cellulose acetate filter cigarette.In addition, the discarded cigarette base of a fruit than the cellulose acetate stub fast the degraded of Duoing, bring remarkable enhancement of environment.But any measure that overcomes the paper flavor also must bring the smoking suitable with conventional cellulose acetate filter cigarette to experience.Overcome " paper flavor " defective before attempt (for example through adding specific spices, like menthol) this point still be unrealized.
To use filter-tip another restriction of paper be them to the poisonous Fen class He Wu – of existence in the volatilization of smoke from cigarette and half volatilization mutually for example the power of holding of staying of phenol, cresols, catechol and resorcinol be lower than cellulose acetate filter; This causes carrying the higher relative yield of the phenolic compound of the filter-tip cigarette of paper.This owing to cellulose acetate filter to the known selectivity of phenolic compound but not the filter-tip any inherent shortcoming of paper.But, still hope to improve the filter-tip phenol of paper certainly and stay the power of holding, so the smoker compares with the cellulose acetate filter cigarette when inhaling the paper filter cigarette under the phenolic compound that can not be exposed to high-load more.
Therefore be desirable to provide the paper flavor effect that has the filter-tip advantage of paper (biodegradability etc.) and do not have to be harmful to and/or have the cigarette filter that stays the power of holding with the similar at least phenols of cellulose acetate filter.
According to the present invention, in first aspect, tobacco smoke filter or filter element are provided, it comprises: the tobacco smoke filter material that comprises paper; With increase flavor additive (for example be selected from the appendix 1 of Commission Regulation (EC) No.1565/2000 and/or the European Union Chemical Groupings List that lists in EU Flavour Information System (" the FLAVIS ") database the 11st type or the 21st type).This filter tip or filter element can comprise that one or more increase the flavor additive.
In this article, term " increase flavor additive " is meant that reduction compares the additive that more puckery more dried smoking is felt in the paper filter cigarette smog to harmful " paper flavor " influence and/or the reduction of cigarette taste with known cellulose acetate filter cigarette.That is to say that containing this taste that increases the paper filter cigarette of flavor additive should be between the normal cigarette relevant with the cellulose acetate filter cigarette of commercial brand in the taste difference.Made according to their chemical characteristic the various trials of flavoring substance classification they are divided into a few class formation related compounds.For this reason, European Union collected flavoring substance 34 chemical classes the name a single – in the appendix 1 of Commission Regulation (EC) No.1565/2000 He in EU Flavour Information System (' the FLAVIS ') database, mention these classifications.The present invention uses and to increase the flavor additive from the 11st type of this list and/or the 21st type.
This increases the flavor additive can be alicyclic lactone (the alicyclic lactone that for example has maximum 20 carbon atoms, for example C 3-C 20Alicyclic lactone); Aromatics lactone (the aromatics lactone that for example has maximum 20 carbon atoms, for example C 6-C 20The aromatics lactone); Aromatic ketone (aromatic ketone that for example has maximum 20 carbon atoms, for example C 6-C 20Aromatic ketone) or secondary alcohol or its ester.This increases the flavor additive can be lactone, and it is a phthalide-type, for example alkyl phthalide, for example (C 1-C 6Branched-chain or straight-chain alkyl)-phthalide.Collected the material list of generally recognized as safe (GRAS) and each material specified numbering (being known as FEMA GRAS number) of Flavor and Extract Manufacturers Association (FEMA).This increases the flavor additive and preferably has (specify and give it) FEMA GRAS number.This increases the flavor additive can be to have FEMA GRAS number lactone (the 11st type); For example χ-valerolactone (specify FEMA GRAS FEMA 3103), χ-caprolactone (FEMA 2556), δ-caprolactone (FEMA 3167), χ-heptalactone (FEMA 2539), χ-caprylolactone (FEMA 2796), δ-Xin Neizhi (FEMA 3214), 4-hydroxyl-3-penetenoic acid lactone (FEMA 3293), 5-hydroxyl-2-decylenic acid delta-lactone (FEMA 3744), 4,4-dibutyl-χ-butyrolactone (FEMA 2372), peppermint lactone (FEMA 3764), dehydrogenation menthofuran lactone (FEMA 3755), 3-butylidenephthalide (FEMA 3333), 3-normal-butyl phthalide (FEMA 3334) and Whiskey lactone (FEMA 3803).This increases the flavor additive also can be sedanolid.Can be used as and comprise the mixture that increases the flavor additive, a part (for example as the mixture that does not split, like the part of plant extracts or vegetable oil or seed or macadamia nut oil) that for example comprises the essential oil that increases the flavor additive comprises this and increases the flavor additive.Comprise that the mixture (mixture that does not for example split is like plant extracts or vegetable oil or seed or macadamia nut oil) that increases the flavor additive can comprise that one or more increase the flavor additive.For example, can comprise this with the form of celery oil (the for example essential oil of celery seed) and increase the flavor additive.The essential oil of celery seed comprises sedanolid and 3-butylphthalide.The known spices of using as cigarette of celery oil, but do not advise as yet before using celery oil with the paper filter cigarette.Comprise that the mixture (mixture that does not for example split is like plant extracts or vegetable oil or seed or macadamia nut oil) that increases the flavor additive preferably has FEMA GRAS number, for example massoia bark oil (FEMA 3747).
