Ideally a 9*n0ral comparison should be made on one
type of
tobacco which has undergone both typos of
processes (redried and
fermented) separately. Howwor, we do not have this
infamation
and the analytical work is limited to a emparison
of redried flue
cured tobacco used in Player`* Medium'. cigarettes
and fermented
Bahia type tobacco used In Maximos cigarettes. .
This work has already
boon reported (RD48p 2,4o58,) and is summarlsod
here.

The above analytical data shows~that fermented
tobacco contains
less sugar but a higher nitrogen content than the
redriod flue cured.
The sugaz decrease is a function of feimentation,
and depending upon such
conditions as t!me of fe=ontationp increased
nitrogen content could also
be a r"ult of this process.
It is interesting to note that though the total
nitrogen content
of the fermented tobacco is greater the nicotine
content is lower# and
it may well be that the alkaline nature of the
main strefs *make of the
#4--
fermented tobacco is due to the greater content of
thoLnitrog*nous fractions.
Of further interest are the ratios of nicotine in
smoke and
tobaoco for both types.
Fermented tobacco - ratio nicotine (snake) = 0.23
R&dried flue cured - ratio nicotine 0(tobacco) ,
0.17
0
This difference suggests that the nicotim present
in the
fe=eAted tobacso is sox@ easily available for
release on smoking*

possibly due to the manner in which It is hold in
the tobacco# *.g. aore,
volatile faltat etc.
Other work being carried out on the volatile phase
of the smoke
using gas chromatographic techniques has indicated
that the smoke from the
fermented tobacco cigarettes is higher In
acotaldehydat isopreft0t piool1A*s
and p-cymene and lower in methyl furanst
pyrittine, allyl acetate and
furfural content than the smoke from redried flue,
cured tobacco.
Thus it would seem that the nitrogenous
fractionstother than
nicotine and py,4dines are probably primarily
responsible for the
alkalinity of the main stream smoke from fermented
tobacco.
