¦ BACKGROUND OF THY INVENTION
The present invention relates to novel tobacco
products, foreign copyist and processes for producing
the novel tobacco pr~d~c~s. The invention relates
principally Jo a process for improving the flavor and aroma
of tobacco and tobacco smoke Additionally a sweet flavor
is imparted to the tobacco smoke.
Addition of flavors to tobacco to enhance the aroma of
a tobacco product as well as the smoke from the tobacco
product is well known in the art and such flavorings are
known to provide enhanced attractiveness of the tobacco
product as far as the ultimate consumer is concerned.
Considerable efforts as relocate Dye outwore or or art
teachings have been made and are being exerted by the
manufacturers of tobacco products to provide a product that
it acceptable to the customer and provides satisfying aroma
and flavor.
It is the general practice in the tobacco industry to
prepare blends of domestic and other tobaccos to provide a
smoking tobacco which has a pleasing flavor and aroma before
and during smoking. In many instances such procedure, are
expensive and prohibited when certain types of tobacco are
in short supply. Additionally, the ever increasing cost of
tobacco raw material make the development of procedures for
2 0 Utah zing less desirable tobaccos even more important.

SUMMARY OF THE INVENTION
The prevent invention relates to the use of
non~nitro~e~ous muckrake ask compound as additives to
tobacco to impure toe aria and other characteristics of
S tobacco, tobacco smote, and flavor.
More particularly, it has been found that the use of
the macrocylic musk compounds as as additive to tobacco
products unexpectedly increases the body of the smoke,
smooths the smoke flavor, and decreases mouth dryness.
More particularly, it has been found that the addition
of macrocylic musk compounds to tobacco in accordance with
the present invention, such as burley, flue cured tobacco,
or oriental tobacco or even reconstituted tobacco or tobacco
substitutes such as various vegetable leaves imparts
amelioration properties and adds a unique characteristic
musk flavor and aroma to the tobacco and the tobacco smoke.
The compounds within the scope of the present
invention may be applied at any point during the processing
of the tobacco or tobacco substitute product as well as any
paper, plug wrap, tipping, filter, or package to achieve the
desired effect.
No prior art disclosure is known relating to the use
of musk or musk type products or non-nitrogenous macrocylic
compounds as flavor ants or aroma imparting vehicles for
tobacco products.
More particularly the present invention provides an
improved tobacco product composition incl~ldin~ macro cyclic
us compounds selected from the props consisting of
issue
cyclohexadecen-7~olide, cyclopentadecanolide,
3-methylcy~lopentadecanone~ cycloheptadecen-9-one or
cyclopetadecanone to provide enhanced aroma and flavor and a
method for producing the same.

SWAHILI
The five previous compounds are included in two
groups, namely lactones (ambrettolide and exaltolide) as
jell as non-lactones mu scone civettone and exalt one).
Mach of the companies is recognized to have isomers, however
evaluation of these products show little difference between
the isomers of the materials and it is believed that all
isomers impart similar effects in the use of the materials
as flavorance for tobaccos.
It has been further found that addition of the
macrocylic musk compounds previously noted to tobaccos as
well as tobacco like products such as reconstituted tobacco
and tobacco substitutes imparts amelioration properties and a
unique characteristic and pleasant musk flavor and aroma to
the tobacco and the tobacco smoke.
It has further been found that the flavor ant may be
added to the tobacco product at any point during the
processing including top flavor casing, top dressing or
application of the stems and/or reconstituted tobacco sheet.
To evaluate the flavor ants a blend of tobacco as shown
in Table I was prepared.

The flavor ants within the scope of the present
invention were added to the blend as discussed hereinafter.
Both filter ventilated and non-filtered cigarettes were
evaluated inn ye blend It was found that neither
cellulose acetate filtration nor ventilation affected the
flavoring qualities of the musk compounds in the tobacco
products.
The tests were conducted in accordance with a
procedure where selected of the components ambrettolide,
exaltolide, muscon, civettone, and exalt one were dissolved
in ethanol.
The test procedure involved generally dissolving the
flavor an as previously described in an ethanol solution of
selected concentration. Using 2 10 micro liter syringe the
solutions were injected into the tobacco sections of the
cigarettes formed from the previously noted blend where each
cigarette had a tobacco weight of 686 milligrams.
Several test samples were prepared using solutions of
flavor ant and ethanol so that cigarettes were provided
having test levels of lo parts per million, 50 parts per
million, lo parts per million, 5 parts per million, l part
per million and .01 part per million of the components
within the scope of the present invention. The cigarettes
were aged for two to three days and then smoked to determine
the optimum application levels.
While effects were noted even at the 0.1 parts per
lZlZZZ~
million level, the optimum for the various components were
found to ye as follows:
ambre~toLide 2-5 parts per million
exaltolide Z 5 parts per million
mu scone 2-5 parts per million
civettone 3-5 parts per million
exalt one 4-9 parts per million
Specific organoleptic effects were perceived upon
smoking the cigarettes and the following was noted:
AMBRETTOL IRE
The optimum application range of ambrettolide was
found to be Jo minimum of 2 to 5 parts per million based on
the weight of the tobacco in the cigarette. The material
provided ameliorating and soothing effect on the smoke
flavor and character. A pleasant characteristic musk type
pack aroma was imparted. It was found that the material is
satisfactory between the 0.1 to 50 parts per million level
to provide an organoleptic effects.
EXULTED
2 to 5 parts per million of exaltolide was found to be
the optimum application rate based on the weight of the
tobacco. An ameliorating soothing effect was noted on the
smoke flavor and character. Also increased smoke body was
noted along with added sweetness and decreased dryness. Top
mixture provided a pleasant characteristic musk type pack
aroma. It was found that the concentration of exaltolide at
0.1 parts per million provide some effect and the
lZ12~Z~
concentrate can be increased to So part per million where
the desired orqanoleptic effects are still noted.
MCKEE
The optimum level of mu scone was found to be 2-5 parts
per million based on the weight of the tobacco. In those
concentrations the ~nu~COQe provide an ameliorate
smoothing effect on smoke flavor and character with
increased smoke body. Added sweet fruity flavor and
decreased dryness was also nutted. Pleasant characteristic
musk type aroma was imparted to the cigarette. It was
further found that the additive level can vary from 0.1 to
50 parts per million to achieve the desired effects.
CIVETTONE
It was found that 3-5 parts per million of civettone
was the optimum application level based on the weight of the
tobacco. An ameliorating smoothing effect was noted on
smoke flavor and character. also the smoke had added body
and a heavy, sweet flavor was imparted. Once again the
material provided pleasant characteristic musk type pack
aroma. It was found that as in previous cases effects were
noted where the additive level varied from 0.1 to 50 parts
per million.
EXALT ONE
The optimum level of exalt one was found to be 4-9
parts per million but the level can Mary from 0.1 to 75
parts per million end still provide the characteristic
ameliorating smooth effect on the smoke flavored
characteristics with increased smoke heady. the blend
l;~lZZ24
further provides decreased dryness with a pleasant musk type
aroma.
The same musk compound as described previously was
applied to pipe tobacco closed of a blend consisting of:
COMPANY PERCENTAGE OF BLEND
Burley 7 4 %
Stems 26%
The effects perceived from smoking pipe tobacco with
the applied materials were generally the same as those found
in cigarettes where the optimum application levels for pipe
tobacco is 1~20 parts per million with a range of 0.1-100
parts per million providing evidences of the desired
effects.
A similar test was conducted using oxahexadecanolide
having two oxygen atoms in the ring structure of the
molecule and the results were generally unsatisfactory. For
example, at the 5 parts per million application level the
effect of the additive was an increase in nasal, throat,
mouth irritation.
The foregoing are but a few examples of preparations
in accordance with the present invention and it is
recognized that other preparations also within the scope so
the present invention will occur to those skilled in the art
upon reading the disclosure set forth herein before.
