LORENTZ ALBERT GROTH, K.G.V. Civil Engineer and Managing Director of The
Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London E.C. "A NEW OR IMPROVED PROCESS FOR PREPARING EXTRACT
FROM FISH, WHALE AND OTHER SEA ANIMALS FOR FOOD AND OTHER PURPOSES
"
A communication to me from abroad by Carl Adolf Sahlström Engineer of
Jönköping in the Kingdom of Sweden.
The object of this invention is the utilization of the flesh of the Shark, whale,
Seal and other sea animals and some kinds of fish and the offal arising from the
curing and drying of cod and other fish (all of which have heretofore been con-
sidered useful only as manure) and the treatment thereof and production therefrom
of a valuable and nutritious extract similar to the well known " Liebeg's Extract
of Meat"
The objectionable taste of the above mentioned kinds of flesh which renders
them unsuitable for human food either in a fried or boiled state, is caused by the
fat which is spread all over the flesh in the form of small balls surrounded by
membranes, which membranes however prevent the fat from contaminating the
flesh only so long as they remain intact It is therefore necessary that these lat
balls should be separated from the flesh in such manner as to prevent the fat from
coming in contact with the portions to be used for food

page_text: According to this invention the raw material is cut up into as small pieces as
possible by mechanical means, and is placed in a vat provided with stirring
apparatus.
A quantity of clean water free from lime is boiled and cooled down to from 6°
to 15° Centigrade and to this is added so much dissolved hypermanganic alkali or
other suitable deodorizer as will impart to the water a light red color, say from 1
to 10 grammes alkali for every 100 litres of water and from 20 to 100 grammes of
ammonia. Sufficient of this liquor is added to the finely cut raw material to give
thereto the consistency of thin gruel, and the stirring apparatus is then set to work.
After a period of from 10 to 30 minutes the mass is removed from the vat and is
placed in a centrifugal apparatus for the purpose of separating therefrom the
superfluous liquor
The inner part of the centrifugal apparatus is preferably covered with cloth.
The mass is soaked in fresh liquor and passed through the centrifugal apparatus as
often as may be found necessary and all the fluid obtained is mixed together and
left to stand in a deep tank for a period varying according to the temperature.
The oil is separated for special treatment and the remaining solid mass is dried
and used for manure.
The fluid thus obtained which is free from any particle of fat is then mixed
with from 1 to 10 grammes of common salt to each 100 litres of the fluid, is boiled
as quickly as possible before the albumen coagulates, and is then filtered. The
clear fluid is evaporated in vacuo or otherwise till it attains the consistency of
treacle, it is then poured into a shallow vessel which can be heated by steam.
From 10 per cent to 8 per cent of sugar.is then added for the purpose of
-preserving the extract and of imparting a taste thereto similar to that of Liebeg's
extract of meat, the extract is heated to a temperature of 100° Centigrade, and
kept constantly stirred until the desired consistency is attained
Vegetables or extracts thereof, or any other flavouring matter or flour or other
material for imparting a higher nutritive power or to give solidity may be added
at pleasure.

A communication to me from abroad by Carl Adolf Sahlström, Engineer, of
Jönköping in the Kingdom of Sweden.
The object of this Invention is the utilization of the shark, whale, seal,
and other sea animals and some kinds of fish, and the offal arising from the
curing and drying of cod and other fish (all of which have heretofore been con-
sidered useful only as manure) and the treatment thereof and production therefrom
of a valuable and nutritious extract similar to the well known "Liebeg's Extract

The objectionable taste of the above mentioned kinds of flesh which renders
them unsuitable for human food either in a fried or boiled state is caused by the
fat which is spread all over the flesh in the form of small balls surrounded by
membranes, which membranes however prevent the fat from contaminating the
flesh only so long as they remain intact. It is therefore necessary that these fat
balls should be separated from the flesh in such manner as to prevent the fat from
coming in contact with the portions to be used for food.
According to this Invention the raw material is cut up into as small pieces as
possible by mechanical means and is placed in a vat provided with stirring
apparatus..
A quantity of clean water free from lime is boiled and cooled down to from 6° to
15° Centigrade and to this is added so much dissolved hypermanganic alkali (or
other suitable deodorizer) as will impart to the water a light red colour, say from 1

The clear fluid is evaporated in vacuo or otherwise till it attains the consistency
of treacle, it is then poured into a shallow vessel which can be heated by steam.
From 0 to 8 per cent of sugar is then added for the purpose of preserving
the extract and of imparting a taste thereto similar thereto to that of Liebegs
Extract of Meat, the extract is heated to a tenperature of 100° Centigrade and
kept constantly stirred until the desired consistency is attained.

material for imparting a higher nutritive power or to give solidity may be added
at pleasure..
Having now described the nature of the said Invention and the manner in which
the same is to be carried into effect, I would have it understood that what I
claim as the invention to be secured by the within in part recited Letters Patent is
Extracting the nutritive parts, namely the albumen and salts from the flesh of
the shark, whale, seal and other sea animals and fish by cutting the raw material
into pieces then soaking it in cold water with which has been mixed ammonia
and some disinfectant such as hypermanganic alkali then mixing the extract with
common salt and sugar and evaporating the same to the required consistency,
substantially as herein before described
In witness whereof I the said Lorentz Albert Groth have hereunto set my
hand and seal this Fourth day of June in the year of our Lord One
thousand eight hundred and eighty three
.
