page_text: 1, ALFRED WILLIAM MAC ILWAINE, of Kingston-upon-Hull, in the County of York,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention principally relates to the production of a new ingredient suitable
for use as, or for admixture with, cattle and other food.
In the process of preparing mustard from mustard-seed there is a certain amount
of refuse material known as ** mustard-dross." This contains an oil, the greater
portion of which is usually extracted by means of expression. The solid matter
remaining possesses a pungent flavour and hitherto has only been suitable for use as
manure. The objects of this invention are, first, to get rid of the pungent qualities
contained in the dross and thus to render the residue fit for use as a food for cattle
and other animals, and secondly, to obtain relatively a greater quantity of oil from the
said dross.
In carrying out this invention, I subject the "mustard-dross" to the action of
volatile solvents and steam in the usual way employed in extracting oil by the solvent
process. The quantity of oil thus obtained from a given quantity of "mustard-
dross" is greater than when the oil is extracted by expression alone, and the solid
residue remaining is free from pungent qualities and adapted for use as, or for
admixture with, cattle and other animal food.

An Improved Manufacture of Cattle and other Food.
I, ALFRED WILLIAM MAO ILWAINE, of Kingston-upon-Hull, in the County of York,
Gentleman, 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 principally relates to the production of a new alimentary substance
or ingredient suitable for use as or for admixture with cattle and other food.
In the process of preparing mustard from mustard-seed there is a certain amount
of refuse material known as "mustard-dross." This contains an oil, the greater
portion of which is usually extracted by means of expression. The solid matter
remaining possesses a pungent flavour and hitherto has not been suitable for use as
cattle or other animal food. The objects of this invention are, first, to get rid of the
pungent qualities possessed by the dross, and thus to render the residue fit for use
as food for cattle and other animals; and secondly, to obtain relatively a greater
quantity of oil from the said dross.
In carrying out this invention, I subject the "mustard-dross" to the action of
volatile solvents and steam in the usual way employed in extracting oil by the solvent-
process. The quantity of oil thus obtained from a given quantity of "mustard-
dross is greater than when the oil is extracted by expression alone, and the solid
residue remaining, being free from pungent qualities, is adapted for use as or for
admixture with cattle and other animal food.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
In the manufacture of food for cattle and other animals from mustard-dross, sub-
jecting the material under treatment to the action of the volatile solvent process for
the extraction of the essential oil and the removal of the pungent flavour, substantially
as herein described.
