Improvements in or relating to the Preservation of Organic
Substances.
A communication from FRANZ FRITZSCHE & COMPANY, Chemical Works,
Hamburg-Uhlenhorst, Empire of Germany.
I, ALFRED JULIUS BOULT of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
:
The materials hitherto employed for preserving organic substances, such as salt,
smoke, alcohol, vinegar and the like, had to be used in very large quantities
compared to that of the substance to be preserved in order to ensure efficiency.
My correspondents have discovered that oxychinolin and acid and neutral salts of
oxychinolin as well as soluble combinations of such salts, such as for instance the
product (chinosol) obtained by the process described in the Specification of Letters
Patent No. 1409 dated 20th January 1896, has a preserving quality of extra-
ordinary power. The said substances prevent the development of microbes much
better than any hitherto employed, such for instance as boracic acid, sulphite of
soda, salicylic acid and the like, and are, as the chinosol for instance not poisonous
if compared with the substances just named or especially with other known strong
antiseptics. Experiments have shown, that these substances ensure, a surprising
success even if used in extremely small quantities, so small that they neither
perceptibly influence the tastes nor are injurious to health. In order that the
invention may be more fully understood the following examples are given.
An animal say a rabbit just slaughtered whose head has been severed can be
sprinkled with a powder consisting of say two parts of chinosol and fifty parts fine
fossil meal; this powder is preferably rubbed uniformly over the animal and
prevents the body from becoming foul; it is sufficient to use 1 gr. of such powder
therefore only 0-04 gr. of chinosol.
The same result is obtained by washing the body with a diluted chinosol solution.
A piece of meat, dipped into diluted chinosol solution, becomes dry without
becoming foul; a piece of meat washed in diluted chinosol solution can be kept a
long time in a closed vessel without getting foul; the meat can be also preserved
by covering it with a solution of gelatine or similar substance to which a little
chinosol has been added; also meat, partly covered by skin, can be preserved by
covering it on its rough side with a solution or powder of chinosol.
Game may be preserved by washing the hole, made by the shot, as soon as
possible and also by washing the stomach and chest regions with a solution of
chinosol after the intestines have been removed.
Eggs covered, with a solution of chinosol, solutions of sugar, gum-arabic,
glue, etc., as also liquids such as beer, and water can be preserved by adding to
them from 1 in 10,000 to 1 in 100,000 chinosol or other soluble oxychinolin
combinations. Seeds of oil and similar objects, which when stored become heated
aud spoiled, are preserved by adding to them a small quantity of fossil meal
saturated with chinosol.

page_text: Fruits, meat and the like are preserved by embedding them in a neutral powder,
such as for instance fossil meal, to which chinosol has been added. The most
widely different organic substances and liquids can be preserved, as for instance
was by adding to it some oxychinolin combination; also serum, solutions of
pepsin, white of eggs, fats, greases, the remains of fish, and other articles can be
preserved by adding watery solutions; the skins by covering them with a solution
or by rubbing in some substance containing oxychinolin. My correspondents wish
it to be understood that they do not confine themselves to the precise proportions
set forth.

I, ALFRED JULIUS BOULT, of 111 Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described in and by
the following statement:-
The material hitherto employed for preserving organic substances, such as salt,
smoke, alcohol, vinegar and the like had to be used in very large quantities
compared to that of the substance to be preserved in order to ensure efficiency;
my correspondents have discovered that oxychinolin and acid and neutral salts of
oxychinolin as well as soluble combinations of such salts, such as for instance the
product (chinosol) obtained by the process described in my correspondents
Application No. 1409 dated 20th January 1896 has a preserving quality of
extraordinary power. The said substances prevent the development of microbes
much better than any hitherto employed such for instance as boracic acid,
sulphite of soda, salicylic acid and the like and are as the chinosol for instance not
poisonous if compared with the substances just named or especially with other
known strong antiseptics. Experiments have shown, that these substances ensure
a surprising success even if used in extremely small quantities so small that they
neither perceptibly influence the taste nor are injurious to health. In order
that the invention may be more fully understood the following examples are
given:-
An animal say'a rabbit just slaughtered whose head has been severed can be
sprinkled with a powder consisting of say two parts of chinosol and fifty parts fine
fossil meal; this powder is preferably rubbed uniformly over the animal and
prevents the body from becoming foul; it is sufficient to use one gramme of such
powder, therefore only 0.04 gramme of chinosol.
The same result is obtained by washing the body with dilute chinosol solution.
A piece of meat dipped into dilute chinosol solution becomes dry without becoming
foul; a piece of meat washed in diluted chinosol solution can be kept a long time
in a closed vessel without getting foul; the meat can be also preserved by covering
it with a solution of gelatine or similar substance to which a little chinosol has been

solutions of sugar, gum-arabic, glue etc., and liquids, such as beer and water, can
be preserved by adding to them from 1 in 10,000 to 1 in 100,000 parts of chinosol
or other soluble oxychinolin combinations. Seeds containing oil and similar
material which when stored become heated and spoiled may be preserved by adding
to them a small quantity of fossil meal saturated with chinosol."
Fruits, meat and the like are preserved by embedding them in a neutral powder,
such as for instance fossil meal to which chinosol has been added. The most
widely different organic substances and liquids can be preserved as for instance
wax by adding to it an oxychinolin substance; whilst serum, solutions of pepsin
white of eggs, fats greases the remains of fish and other articles can be preserved
by adding or applying dilute solutions and skins by covering them with a solution
or by rubbing in some substance containing oxychinolin.
My correspondents wish it to be understood that they do not confine themselves
to the precise proportion set forth.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents and in what manner the
same is to be performed, I declare that what I claim is :-
1. The improved method of preserving organic substances, food and the like by
the application or addition of oxychinolin or chemical or other combinations of
oxychinolin or its salts substantially as described.
2. Preserving organic substances food and the like by means of the product
obtained by the process described in the Specification of British Patent filed
January 20 1896 Number 1409 substantially as described.
3. The method of preserving organic substances by sprinkling the substances
with or storing them in a neutral or inert powder to which is added oxychinolin
or chemical or other combination of oxychinolin and its salts substantially as
described.
4. The method of preserving organic substances by sprinkling the substances
with or storing them in a powder obtained by the process described in the British
Patent Number 1409 of 1896.
5. The method of preserving organic substances by covering them with a
solution of gelatine or other indifferent or inert substances to which a small
percentage of oxychinolin or oxychinolin combination has been added substantially
as described.'
6. The method of preserving organic substances by dipping them in a solution
of oxychinolin, or oxychinolin combinations, substantially as described.
