PROVISIONAL SPECIFICATION.
Improvements in or relating to the Treatment of Separated Milk
for Alimentary Purposes.
I, HUBERT HIGGINS, of 4, Trinity Street, Cambridge, in the County of Cambridge,
Demonstrator of Anatomy to Cambridge University, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the treatment of separated milk, that is milk from
which the cream has been removed by mechanical means, so as to obtain its more
valuable constituent, caseinogen, in a pure or substantially pure condition for
alimentary purposes.
The agent I prefer to employ for precipitating the caseinogen from the other
constituents of milk is hydrochloric acid. I then wash the caseinogen precipitated
in this manner in about 150 gallons of boiling water, and I have found that this
causes the caseinogen to assume a sticky condition in which it is capable of being
stretched or drawn out in long strings or of being rolled out into thin sheets. The
caseinogen shortly after it is withdrawn from the boiling water in this sticky state
assumes a somewhat friable condition, and shows moreover no tendency to adhere
to caseinogen in a like condition or any other substance that it may come in
contact with. When in a friable condition the caseinogen is capable of being
ground by a suitable grater into a moist powder, in which state it can be added to
bread or other alimentary substance, or it may be dried and subsequently ground
between rollers into a fine powder or flour for future use.

Improvements in or relating to the Treatment of Separated Milk
for Alimentary Purposes.
I, HUBERT HIGGINS, of 4, Trinity Street, Cambridge, in the County of Cambridge,
Demonstrator of Anatomy to Cambridge University, 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 the treatment of separated milk, that is milk from which
the cream has been removed by mechanical means, so as to obtain its more valuable
constituent, caseinogen, in a pure or substantially pure condition for alimentary
nurnoses.

page_text: The agent I prefer to employ for precipitating the caseinogen from the other
constituents of milk is hydrochloric acid; I then wash the precipitated caseinogen
in water heated to a temperature of between 180° Fh. and 212° Fh.; the best
result being obtained with water at about 200° Fh., employing about 150 gallons
of water for every 50 pounds of precipitate.
This treatment causes the caseinogen or milk proteids to assume a peculiar physical
condition in which the precipitated mass tends to adhere together. When first
removed from the water it can be rolled between wooden rollers coated with
rubber, or in some other convenient apparatus, into thin sheets, which may be
cut to a convenient length and hung on rounded strips or bars of wood to be dried.
The great advantage of this plan is rapid and efficient desiccation.
Although when withdrawn from the hot or boiling water the caseinogen is in
this pliable sticky condition, after standing a short time it assumes a somewhat
friable condition, and shows no tendency to adhere to caseinogen in a like
condition or to any other substance that it may come in contact with and may be
ground by a suitable grater into a moist powder. In this form it may be
mixed with flour, meal, rice, semolina, tapioca, oatmeal, arrowroot, gluten,
sugar, glucose or the like, in order to add to the nutritive value of such
substances.
Or the product may be thoroughly dried and subsequently ground between
rollers into a fine powder or flour for future use.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The treatment of caseinogen precipitated from separated milk with hot water
substantially in the manner described.
2. The food product prepared from caseinogen alone or in combination with
other alimentary substances substantially in the manner described.
Dated this 25th day of February 1898.
