Description
Technical field
The present invention relates to composition measurement technical fields in smoke-free tobacco product adjuvant materials, and in particular to a kind of packet containing cigarette
Li in pack+、Na+、NH4 +、K+、Mg2+、Ca2+The content assaying method of ion.
Background technique
Without burning or not when smoke-free tobacco product (Smokeless tobacco products, STPs) refers to use
The tobacco product for generating flue gas, can be divided into mouth type (Oral STPs) and nose type (Nasal STPs) two according to usage mode
Big type.Mouthful include chewing tobacco (Chewing tobacco), containing the multiple types such as cigarette, molten cigarette with type STPs, wherein containing cigarette be its most
Main product form has American Moist Snuff type to contain two kinds of cigarette containing cigarette, Sweden's Snus type, and the usage mode of the two is all
It is put between gum and lip, it is entirely different with traditional snuff (Nasal tobacco).Each domestic mouth containing type smokeless tobacco in Northern Europe
Product belongs to Swedish Snus type, and sample pH value is within the scope of neutral meta-alkalescence；The U.S. produces buccal smokeless tobacco product
Existing American Moist Snuff, and have Swedish Snus, therefore, pH wider range of sample.
Buccal smokeless tobacco product is divided into bulk and packed two major classes from the packaging, referred to as in bulk containing cigarette and packed to contain
Cigarette.It is in bulk to contain cigarette containing cigarette (Loose Tobacco) for tradition, it is divided into crin (Long Cut) and filament (Fine Cut), uses
When, take it is a handful of be placed between lip and gum, gently suck make tobacco or fragrance component through saliva between teeth space enter oral cavity, produce
Raw organoleptic effect.The behavior that such product spues after is most unseemly, and has dregs residual.The packed of modern production contains cigarette
(Pouch Tobacco) is charged material into penetrability pouch, is not only easy to use consumption, but also will not pollute oral cavity.In recent years, respectively
Big tobacco enterprise is developed one after another and the bagged product for the famous brand name that releases one after another, such as R. J. Reynolds Tobacco release " camel " card series bag
Dress is packed containing cigarette etc. containing cigarette, luxuriant and rich with fragrance not tobacco release " Marlboro " card series.
In recent years, global tobacco control dynamics constantly enhances, and smoke-free tobacco product has been increasingly becoming the important tobacco of one kind and has disappeared
Fei Pin, and represent the important trend of international Field of Tobacco.But there is presently no to smoke-free tobacco product auxiliary material
Ingredient and its containing quantifier elimination report.
It is packed to contain penetrability pouch used in cigarette (Pouch Tobacco), it, may directly with the oral contact of consumer
Mouthfeel containing cigarette, taste can be impacted, ingredient may also can affect to consumer.Especially Li+、Na+、NH4 +、K+、Mg2+、Ca2+It is affected Deng cation to consumer, therefore, it is necessary to monitor above-mentioned in packaging bag containing cigarette
