PROVISIONAL SPECIFICATION.
A New or Improved Method of Obtaining and Preserving the
Soluble Albumen of Animal Food.
We, JOHN LAWSON JOHNSTON of 30 Farringdon Street, London, Manu-
facturer, and BOVRIL LIMITED, of 30 Farringdon Street, London, Manufacturers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved method or process for obtaining the
soluble albumen of flesh intended for human food and for preserving it in a perfect
condition for an indefinite period without the aid of antiseptic or other artificial
preservatives.
In consequence of the rapidity with which decomposition occurs in the case of
the soluble constituents of animal foods it has hitherto been found impossible to
keep the same in an uncoagulated state for any length of time without the
admixture or treatment with antiseptics. This practice is not satisfactory or
beneficial in its results.
To carry out this invention it is necessary that the juices of fresh beef, mutton,
or other animal foods be extracted from the fresh meat by hydraulic or other
pressure. The juices so pressed out are received into suitable vessels (glass being
preferred). The juices are then spread upon slabs or sheets of glass or other
suitable material and subjected by any known and suitable process to a temperature
under that of the coagulating point of albumen. When the substance has become
perfectly dry or desiccated it is scraped from the slabs or sheets above referred to
and packed in airtight packages and in this condition it will keep for an indefinite
period.

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:—
This invention relates to a new or improved method or process for obtaining the

To carry out this invention it is necessary that the juices of fresh beef, mutton,
or other animal food be extracted from the fresh meat by hydraulic or other
pressure. The juices so pressed out are received into suitable vessels (glass being
preferred). The juices are then spread upon, slabs or sheets of glass or other
suitable material and subjected by any known and suitable process to a temperature
under that of the coagulating point of albumen. When the substance has become
perfectly dry or desiccated it is scraped from the slabs or sheets above referred to
and packed in airtight packages and in this condition it will keep for an indefinite
period.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The process set forth in the foregoing Specification for obtaining the soluble
albumenoids of animal flesh and for preserving the same in a condition suitable for
human food.
