The Production of a New Glutinous Material similar to Gum Arabic
and other Bye Products from the Seed Kernels of the Fruit of
the Carob Tree (Ceratonia).
I, AUGUST NIEMÖLLER, of Gutersloh in Westphalia, Germany, Mill' Owner, do
hereby declare the nature of this invention to be as follows:-
The fruit of the Carob Tree (Ceratonia) known as "St. Johns bread," which has
been cultivated from time immemorial, is used in various forms both as human food
and as cattle food. In its native country it serves as the main article of food for the
poorer classes, and various other substances are prepared therefrom, such as syrup,
brandy, buteric acid and buteric ether; also a substitute for coffee and a food for
cattle, which is used to a very large extent in this country.
My present invention has for its object to utilize the seed kernels of this fruit for
the production therefrom of a glutinous material similar to gum arabic, and also a
coloring matter, and an alimentary substance.
Figs. 1, 2 and 3 of the accompanying drawing shew.the said seed kernel, Fig. 1
being a view of the complete kernel of the natural size, Fig. 2 is a section on
line xx
Fig. 1, and Fig. 3 is a section on line y y.
These kernels consist of the red brown and slightly lustrous shell a which
encloses two hard yellowish slightly transparent discs or pieces between which is
the germ d together with a mealy disc or layer c. The shell a contains a brown
coloring matter, which can be extracted by boiling or other suitable means.
The two principal parts 6 consist mainly of a glutinous substance which is far
superior to other vegetable glutinous materials, and is nearly equal to gum arabic
in quality.
The germ-discs are of a mealy character, and can be used for human or cattle
food.
In order to obtain the above named substances in a separate form, the kernels of
the St. John's bread fruit are first freed from their shell, which may be effected
mechanically by any known means, such as those used in milling. The shells are
employed, as,above described for the production of a brown colouring matter, which
is extracted by boiling or by other means.
The discs containing the glutinous material are then reduced to small
fragments, and are separated from the inner mealy disc c, this being effected by a
simple sifting process.
The parts care ground to meal and are brought into commerce as an article
of food.
For preparing the glutinous material the particles containing the same, either
reduced or not, to very small fragments or not, are treated with hot water, whereby
the glutinous material will be produced. If this material does not possess a
sufficient cementitious property, the liquid is concentrated to any desired degree.
In order more readily to extract the glutinous material, the particles can be first
reduced to powder, which is then treated as above described..
According to another method the entire kernel is treated with water or other
liquid after removal of the shell, for extracting the glutinous material after which
the residual mealy and other substances of the kernel are dried and reduced to
fragments or powder.
The glutinous material may be introduced into commerce either in the liquid or
solid form, or the entire or comminuted parts of the kernel that yield the said
substance may be so introduced.

page_text: The glutinous material thus produced is of a fine, clear, slightly yellow appear-
ance, and possesses very great binding power.

The Production of a New Glutinous Material similar to Gum Arabic
and other Bye Products from the Seed Kernels of the Fruit of
the Carob Tree (Ceratonia).
I, AUGUST NIEMÖLLER, of Gutersloh in Westphalia, Germany, Mill Owner,
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 :-
66
The fruit of the Carob Tree (Ceratonia) known as St. Johns bread" which has
been cultivated from time immemorial, is used in various forms both as human food
and as cattle food. In its native country it serves as the main article of food for
the poorer classes, and various other substances: are prepared therefrom, such as
syrup, brandy, buteric acid and buteric ether; also a substitute for coffee and a
food for cattle, which is used to a very large extent in this country.
My present invention has for its object to utilize the seed kernels of this fruit for
the production therefrom of a glutinous material similar to gum arabic, and also a
coloring matter, and an alimentary substance.
Figs. 1, 2 and 3 of the drawing accompanying my Provisional Specification shew
the said seed kernel, Fig. 1 being a view of the complete kernel of the natural size,
Fig. 2 is a section on line a Fig. 1, and Fig. 3 is a section on line y y.
These kernels consist of the red brown and slightly lustrous shell a which
encloses two hard yellowish slightly transparent discs or pieces between which is
the germ d together with a mealy disc or layer c. The shell a contains a brown
colouring matter, which can be extracted by boiling or other suitable means.
The two principal parts consist mainly of a glutinous substance which is far
superior to other vegetable glutinous materials, and is nearly equal to gum arabic
in quality.
The germ-discs are of a mealy character, and can be used for human or cattle
food.
In order to obtain the above named substances in a separate form, the kernels of
the St. John's bread fruit are first freed from their shell, which may be effected
mechanically by any known means, such as those used in milling. The shells are
employed, as above described for the production of a brown colouring matter, which
is extracted by boiling or by other means.
The discs b containing the glutinous material are then reduced to small fragments,
and are separated from the inner mealy disc c, this being effected by a simple
sifting process.
The parts c are ground to meal and are brought into commerce as an article
of food.
For preparing the glutinous material the particles containing the same, either
reduced or not, to very small fragments, are treated with hot water, whereby the
glutinous material will be produced. If this material does not possess a sufficient
cementitious property, the liquid is concentrated to any desired degree.
In order more readily to extract the glutinous material, the particles can be first
reduced to powder, which is then treated as above described.
According to another method, the entire kernel is treated with water or other
liquid after removal of the shell, for extracting the glutinous material, after which
the residual mealy and other substances of the kernel are dried and reduced to
fragments or powder.
The glutinous material may be introduced into commerce either in the liquid or

page_text: solid form, or the entire or comminuted parts of the kernel that yield the said
substance may be so introduced.
The glutinous material thus produced is of a fine, clear, slightly yellow
appearance, and possesses very great binding power.
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. A process for the production of glutinous material from the seed kernels of
the fruit of the Carob tree (Ceratonia) consisting in first separating the kernel
from its shell, and then mechanically reducing the same to fragments, and separa-
ting the particles containing the glutinous material from the mealy particles by
sifting, substantially as described.
2. The production of glutinous material from the seed kernels of the fruit of the
Carob tree, by first softening the entire seed in water, and after separating the
shell from the kernel, treating the latter with water or other liquid so as to dissolve
the parts lying underneath the shell, which contain the glutinous material, and to
separate the same from the central mealy portions, substantially as described.
3. The production of a brown colouring matter from the shells which are
obtained by the extraction of the seed kernels of the Carob tree, by boiling the
shells, or otherwise extracting the colouring matter therefrom, substantially as
described.
4. The treatment of the seed kernels of the Carob tree for preparing an article
of food therefrom, consisting in first removing the parts containing the glutinous
material from such kernels, and then reducing to fragments or powder the central
mealy portions thereof, substantially as described.
