PROVISIONAL SPECIFICATION.
Manufacture of Albuminous Products Soluble in Water from Seeds of
Plants.
I, OLIVER IMRAY, of No. 28, Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention (as communicated to me from abroad by The Farbwerke vormals Meister
Lucius and Brüning, of Hoechst /Main, in the Empire of Germany, Chemical
Manufacturers), to be as follows:
-
Oil cakes, used as cattle food, obtained from seeds in the oil manufacture contain
proteinė substances in large quantities. The present invention has for its object
the separation of these proteine substances in such a manner as to allow of their
being used for nourishment.
The process applied to cakes from cotton seeds may be thus illustrated.
The cotton seeds freed from oil by pressure are finely ground and boiled with ether
or ligroine in order to remove all fatty matters.
The pulverised mass, freed from fat is then suspended in a large quantity of water
and to this mixture, heated to 60° C., is added the quantity of soda-lye which is
requisite for dissolving the albuminous substance, this quantity to be ascertained by
titration.
The whole is then heated and stirred for several hours at 80° C., then filtered
and evaporated to dryness in vacuo. The residue is the-sodium salt of the albu-
minous substance, being a yellow to brown powder, easily soluble in warm water
and of agreeable taste and odour.
If an ammonia solution is used in extracting the seeds, then an excess of ammonia
is best; the albuminous substance from the filtered solution being precipitated with
hydrochloric or acetic acid. The substance is then freed by washing from excess
of acid and is transformed into the sodium salt by dissolving it in just the necessary
quantity of soda or soda-lye and then evaporated to dryness, as before, in vacuo.

nature of this invention (as communicated to me from abroad by The Farbwerke
[Price 8d.1

page_text: vormals Meister Lucius and Brüning, of Hoechst /Main, in the Empire of Ger-
many, Chemical Manufacturers), and in what manner the same is to be performed,
to be particularly, described and ascertained in and by the following statement;
Oil cakes, used as cattle food, obtained from seeds in the oil manufacture contain
proteine substances in large quantities. The present invention has for its object
the separation of these proteine substances in such a manner as to allow of their
being used for nourishment.
.
The process applied to cakes from cotton seeds may be thus illustrated.
The cotton seeds freed from oil by pressure are finely ground and boiled with ethe:
or ligroine in order to remove all fatty matters.
The pulverised mass, freed from fat is then suspended in a large quantity of water
and to this mixture, heated to 60° C. is added the quantity of soda-lye which is
requisite for dissolving the albuminous substance, this quantity to be ascertained by
titration.
The whole is then heated and stirred for several hours at 80° C., then filtered
and evaporated to dryness in vacuo. The residue is the sodium salt of the albu-
minous substance, being a yellow to brown powder, easily soluble in warm water
and of agreeable taste and odour.
If an ammonia solution is used in extracting the seeds, then an excess of ammonia
is best; the albuminous substance from the filtered solution being precipitated with
hydrochloric or acetic acid. The substance is then freed by washing from excess
of acid and is transformed into the sodium salt by dissolving it in just the necessary
quantity of soda or soda-lye and then evaporated to dryness as before.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The herein described manufacture of albuminous products soluble in water
from seeds by removing fatty matters and treating the seeds with alkali so as to
dissolve the albuminous substances then evaporating the solution to dryness.
2. The sodium salt of albuminous substances obtained from seeds as above set
forth.
