Improved Means for Preserving Articles of Food.
I, ALEXANDER POEHL of Wassily, Ostrov, 7th Line No. 18, St. Petersburg,
Russia, Professor of Chemistry, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention relates to the use of ethereal oils in combination with common salt
for the preservation of fish and flesh. The putrifaction of articles of food is
produced by the action of Bacteria and by fermentation.
In salting fish and flesh the salt has more an antifermentive than an anti-
bacterial action.
Some kinds of Bacteria are not at all effected by salt. Thus in the digestive organs
of Astrahan herrings I have often found a kind of Bacteria which develops its
active properties in concentrated salt solutions. The casual appearance of putrifaction
in well salted herrings may be ascribed to the activity of such Bacteria.
The problem of preserving meat and fish consists in the application of such
antiseptic means that act restrictively, simultaneously upon the fermentive processes,
and on the activity of the micro-organisms.
After having studied for ten years the antiseptic properties of the ethereal oils I
have come to the conclusion that some ethereal oils have a considerable restrictive
action on the activity of Bacteria in the presence of salt. This property is possessed
more particularly by oil of mustard cinnamon oils, and oil of cloves.
Trials with fishes and flesh afforded very satisfactory results with the combination
of one of these oils, or a mixture thereof, with salt, these results being confirmed
by bacteriological tests.
When using one part of an ethereal oil (or of a mixture of two or more) with
from ten to twenty-five thousand parts of salt solution, a perfect antiseptic action
was obtained,

page_text: In place of the ethereal oil of mustard, an equivalent quantity of mustard meal
can he used.
The ethereal oil has no detrimental effect on the health when used in the above
state of dilution.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is :-
1. The use, for preserving flesh and fish, of ethereal oils together with salt,
substantially as herein described.
2. The use for preserving flesh and fish, of mustard meal together with salt,
substantially as herein described.
