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 hydro-chloric 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, and I find that the caseinogen in
this form instead of being rolled into thin sheets as described in a concurrent,
application, can be advantageously formed into blocks or rolls and allowed to partially
dry. The caseinogen in this condition is capable of being grated or ground into a
fine powder by any suitable means, and if this powdery substance is arranged in
layers of say from half an inch to one inch in thickness, and dried still further,
the particles will be found to adhere to one another in such a manner as to form
a material somewhat resembling thin slices of bread. If this product is dried still
further it will become crisp and dry, and will form a highly digestive and nutritive
food product.

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
Durposes.

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 caseinogen precipitated
in this manner in boiling water, employing about 150 gallons for every 50 lbs. of
precipitate, and I have found that this causes the caseinogen to assume a sticky
condition; the caseinogen in this form instead of being rolled into thin sheets as
described in a concurrent application, can be advantageously formed into blocks or
rolls and allowed to partially dry. The caseinogen in this condition is capable of
being grated or ground into a fine powder by any suitable means, and if this
powdery substance is arranged in layers of say from half an inch to one inch in
thickness, and dried still further, the particles will be found to adhere to one another
in such a manner as to form a material somewhat resembling thin slices of bread.
If this product is dried still further it will become crisp and dry, and will form
a highly digestive and nutritive food product.
After precipitation and before being formed into blocks or rolls, the caseinogen
may if desired be mixed with other alimentary substances such as flour, rice, semolina,
tapioca, gluten, glucose or the like, and flavouring agents may be added according
to taste.
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
The food product prepared from caseinogen either alone or in combination with
other alimentary substances substantially in the manner described.
