How FlavOring Extracts are Made.

"There is mighty little genuine fruit
extract in the sirups and fiavors of COM
merce," the chemist of manufactur-
ing house said, pushing aside glass jars,
strainers and retorts, SO as to make a
clear space for some of his books of
formulas. &C Natural iavors are both
weak and costly. For instance, if you
sugar down pineapples or strawberries
you get delightful natural strip, but
your white sugar alone will cost you
eighty cents gallon, and the fruit is ex-
pensive, as you know. The flavor is
just at its proper strength and will not
go a great ways in flavoring additions
to the sirup; and so only small por
ton of the fruit sirups and essences of
commerce have any fruit about them.

He unstopped vial of thin, transpar-
ent liquid. 1t diffused a strong pineap-
pie odor of irritating pungency.
That" he said, sis butyric acid.
Mixed with alcohol, it is the pineapple
oil of commerce, and it enters into
nearly every flavor manufactured and
into most perfumes. 1t is extracted
from rancid fat. The tallow oil which
is the basis of artificial butter will fur
nish it. Another prominent ingredient
of artificial favors is amyle, which you
will know better by the name OF fusel
oil. Some one of its compounds go
into the manufacture of the flavors of
pineapple, strawberry, raspberry, april
cot, pear, orange and apple. Com
pounds of methyl, an extract OF
coal tar, are also much used.
Succinic acid, obtained from am
Der; sebacic acid, extracted
from fat; and benzoic acid, originally
extracted from vegetable resin, bat
now made from naphthalne, a coal-oil
product, are also much used in various
shapes. Formic acid, another ingredi-
ent, was originally derived from ants,
and hence its name is derived from the
Latin word for ant, t0rnlicG. But it is
now manufactured artificially. Chloro-
form goes into some favors, notably
grape essence, and oxalic acid goes into
the bloom of gooseberry, apricot, lemon
and apple. Tartaric acid is also largely
used Most of,these substances are used
in the form of others, and their strength
of odor is due to their exceeding volatil-
ity"
care not such compounds injuri-
ousP"
"Not when used simply for favoring
purposes" was the answer. " The
reason why they may be used to initiate
natural fl 'vors with such success is
doubtless due to the fact that the flavors
of the natural fruits are due to their
presence. Butyric acid is naturally
present in the pineapple, tartaric acid in
wine, citric acid in lemons, and oXalic
acid in gooseberries. While artificial
favors or essences would be poisonous,
taken in large quantities, it does not fol
low that their use as favors is injurious
any more than that almonds should not
be eaten because their concentrated ex-
tract is poisonous. As matter of fact
soda water flavors and candy tlavors are
almost invariably artificial, and the bou-
quet and flavor of many bottle of wine
is due to the various amylic or fusil oil
others.

thing often when have drunk the sweet

"Sulphuric acid" he said, sis not a
healthful article of diet; but, as | said
before, thing may be perfectly inno-
cent in diluted shape and IN very
small quantity that would be hurtful in
a concentrated form. Odd, isn't it,
that delicate flowers and perfumes
should come from the refuse of the alb
battoir and the coal oil distillery? But
great many pleasant things have
humble origin. "-New York San.
