Managing Director of The Universal Inventors and Patentees Financial
Company Limited 30 Finsbury Pavement London E.C. for an Invention of
"A NEW OR IMPROVED PROCESS FOR EXTRACTING AND PRESERVING THE
OIL FROM FISH, WHALE, AND OTHER SEA ANIMALS" communicated to
him from abroad by Carl Adolf Sahlström, Engineer, of Jönköping in the
Kingdom of Sweden.
PROVISIONAL SPECIFICATION left by the said Lorentz Albert Groth at
the Office of the Commissioners of Patents on the 5th December 1882.
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 EXTRACTING AND
PRESERVING THE OIL FROM FISH WHALE AND OTHER SEA ANIMALS," a com-
munication to me from abroad by Carl Adolf Sahlstrom, Engineer of Jönköping
in the Kingdom of Sweden
The object of this invention is the production of a pure colourless and tasteless
oil from fish whale and other sea animals
Portions of fish whale or other sea animals are finely cut up by suitable
mechanical means and mixed in an appropriate vessel or apparatus with a solution
consisting of from one half to ten grammes of hypermanganic alkali together with
from ten to fifty grammes of ammonia to every 100 litres of water. The
manganese acts as a deodorizer and removes all objectionable smell and taste
which invariably exist in such raw material when not in a perfectly fresh state.
The mass is then separated froin the liquid by means of a press a centrifugal or
other suitable apparatus and the liquid is afterwards allowed to stand until the oil

is repeated till all the fat has been extracted The fat thus obtained is then heated
to 60° or 80° Centigrade whereby the bursting of the membranes covering the
microscopical balls of fat is effected and. the oil flows out in a clear and pure state
It is then left to stand in deep vessels in order that the solid matter may settle at
the bottom leaving the oil perfectly clear and with scarcely any taste or smell thus
rendering it applicable to the most delicate uses
It will be understood that by first deodorizing the raw material the fat on being
released from the cells and coming in contact with such raw material will not
absorb any bad smell or taste therefrom but will remain in its primitive state while
the low temperature used prevents any discoloring of the oil which. on the contrary
is obtained as colourless as when in its cells

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 EXTRACTING AND
PRESERVING THE OIL FROM FISH, WHALE, AND OTHER SEA ANIMALS," A com-
munication to me from abroad by Carl Adolf Sahlström, Engineer of Jönköping,
in the Kingdom of Sweden.
The object of this invention is the production of a pure colorless and tasteless
oil from fish whale and other sea animals
Portions of fish whale and other sea animals are finely cut up by suitable
mechanical means and mixed in an appropriate vessel or apparatus with a solution
consisting of from one half to ten grains of hypermanganic alkali together with
from ten to fifty grammes of ammoni or other suitable alkaline to every 100 litres
of water,
The manganese acts as a deodorizer and removes all objectionable smell and
taste which invariably exist in such raw material when not in a perfectly fresh
state.
The mass is then separated from the liquid by means of a press a centrifugal or
other suitable apparatus, and the liquid is afterwards allowed to stand until the oil
has separated.
The washing of the raw material with the above mentioned solution is repeated
till all the fat has been extracted. The fat thus obtained is then heated to 60°
or 80° Centigrade, whereby the bursting of the membranes covering the
microscopical balls of fat is effected, and the oil flows out in a clear and pure state.
It is then left to stand in deep vessels in order that the solid matter may settle
at the bottom leaving the oil perfectly clear and with scarcely any taste or smell,
thus rendering it applicable to the most delicate uses.
It will be understood that by first deodorizing the raw material, the fat on being
released from the cells, and coming in contact with such raw material will not
absorb any bad smell or taste therefrom but will remain in its primitive state
while the low temperature used prevents any discolouring of the oil which on the
contrary is obtained as colourless as when in its cells.
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
Producing a tasteless and colourless oil from fish whales and other sea animals
by cutting up the raw material and treating it with cold water to which has been
added ammonia or other suitable alkaline matter and a disinfectant such as
hypermanganic alkali substantially as hereinbefore 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.
