Enumerating embodiment below, more specifically the present invention will be described, but as long as not departing from purport of the invention, so that it may To be suitable for change.

To yellow pipe tobacco (Japan produces) 100mg, the liquid for mixing propylene glycol and glycerol with 1:1 (weight ratio) is added 100mg, addition are calculated as acid shown in the table 1 of 5 mass % with the mass conversion of composition entirety, have made sample.It needs to illustrate , for pipe tobacco, after being crushed in advance with home-use mixer, with sieve (manufacture of AS200, Retch company) in condition: It is vibrated 2 minutes under amplitude-1.5mm/ " g ", has used sieve diameter 0.5mm sieve below.

The sample of production is set to the trade name sold by Japan tobacco Inc in a manner of pasting " Ploom (registered trademark) " dedicated pod is placed 2 days or more under conditions of 22 DEG C, humidity 60%.It should be noted that right For the heating temperature (when steady running) of pipe tobacco when using Ploom, measured in advance by using thermocouple, it is thus identified that be 160 DEG C~170 DEG C or so.

In smoking test, using smoking machine (Borgwaldt, RM-26), the pod of production is installed on Ploom, Under defined smoking conditions (55ml/2S, smoking interval 30s), the evaporation capacity of the fragrant smell ingredient of initial stage 10puff is measured.It needs Illustrate, the easy nicotine of fragrant smell composition measurement is selected as in this experiment as component target.Cigarette trapping uses sword Bridge filter pad (Cambridge filter pad) carries out vibration in 40 minutes to trapping to the cigarette on filter with methanol solvate and mentions It takes, nicotine is quantified with GC-FID.

The sense evaluation of smoking test is implemented by 4 people, with 1~7 this 7 stages to " fragrant smell hinders sense " and acid " chemical odor " of taste form is evaluated to implement." chemical odor " refers to chemicals smell, is in people's smoking this respect Upper undesirable stink.Numerical value is bigger, indicates that chemical odor is stronger.In the result of the present embodiment, fragrant smell hinders sense and chemistry The evaluation of estimate of smell be 2 situations below under, be estimator can sufficiently Recognition Different value, be denoted as the region of excellent effect. For evaluation, value is recorded by feeling of experiencing in smoking.

The physics value, the evaporation capacity of fragrant smell ingredient, the result of sense evaluation of acid are shown in table 1.

[table 1]

Type/the physics value and evaluation result of 1 acid of table

The relationship for the evaporation capacity for indicating the first acid ionization constant and fragrant smell ingredient of acid is illustrated in Fig. 2.According to figure 2, the fragrant smell component amount of the small acid of the first acid ionization constant is low, when acid ionization constant is 4.0 or more, obtains almost most of The sour result for reaching equal extent with un-added fragrant smell component amount.According to this result it is found that by using the first acid dissociation The acid of 4.0 or more constant, will not cause the reduction of the evaporation capacity of fragrant smell ingredient.If considering pH possessed by acid, due to the One acid ionization constant is mostly 6.0 hereinafter, it is 4.0 or more and 6.0 or less that therefore ideal range, which is the first acid ionization constant,.

In addition, will indicate that the boiling point that the first acid ionization constant is 4.0 or more and 6.0 acid below hinders sense with fragrant smell Relationship is illustrated in Fig. 3.Know that almost all of acid can reduce fragrant smell obstruction sense when boiling point is more than 366 DEG C or more, it is known that Boiling point hinders the reduction of sense to be important fragrant smell.

In addition, the first acid ionization constant will be indicated for the boiling point of 4.0 or more and 6.0 acid below and the relationship of chemical odor Be illustrated in Fig. 4.Know that the chemical odor for the acid that boiling point is 366 DEG C or more is also lower.It should be noted that acid boiling point and Speech, when the temperature is excessively high, the burst size of heat tracing become a small amount of, therefore, it is considered that it is preferred that 600 DEG C or less.

It as can be observed from the foregoing, is 4.0 or more and 6.0 or less, boiling point is 366 DEG C by using the first acid ionization constant of acid Above and 600 DEG C of acid below, under conditions of maintaining fragrant smell component amount, the influence to smell, fragrance is less and can It reduces fragrant smell and hinders sense.

The sour content of the arabo-ascorbic acid of embodiment before, lignoceric acid, nonadecylic acid is changed by 5 mass % Implemented in addition to this by method same as embodiment before for 3 mass %, 1 mass %.It should be noted that this Since the evaporation capacity of fragrant smell ingredient is same in evaluation, be only conceived to the effect that sense is hindered fragrant smell.

[table 2]

Type/the physics value and evaluation result of 2 acid of table

The relationship for indicating sour content and fragrant smell obstruction sense is illustrated in Fig. 5.It is able to confirm that according to Fig. 5, makes content In the case where reducing to 1 mass %, sour effect is also high.This is because even if the high acid of effect is few amount, can also send out merely Wave effect.The acid such as arabo-ascorbic acid, lignoceric acid, nonadecylic acid can be evaporated, by cold due to boiling point height by heating It coagulates after generating aerosol, the property rested in particle is strong, even if diluting in oral cavity when smoking, can also rest on aerosol In, therefore high effect can be obtained in anticipation.In the case that the content of acid is superfluous, feature possessed by acid is easy to embody, therefore examines Considering content appropriate is 10 mass % or less.

Change generates the liquid of aerosol, in addition to this, by with before embodiment and the same method of comparative example it is real Test is applied.In this test, the solvent as the liquid for generating aerosol also uses glycerol, double vinegar other than propylene glycol Ester (diacetin), triethyl citrate (TEC), acid has used nonadecylic acid.Show the result in Fig. 6.Known to used the third two In the case where alcohol, fragrant smell hinders sense highest, and the case where other liquid is low.It is easiest to show the generation gas of effect as a result, The liquid of colloidal sol is propylene glycol, it may be said that with whole amount or all effective comprising this technology in the case where propylene glycol on a small quantity.
