AND METHOD OF MAKING EXTRACTS OR ESSENCES THEREFROM AND MANU-
FACTURING COMPOUNDS THEREOF.
"
This Invention has for its object improvements in the method of treating
the fruit scientificallyknown as ceratonia seliqua, and the seed scientifically known
as vicia sativa, and that commercially known as dholl, and the date fruit, part of
which are founded on those described in the Specification of former Letters Patent
granted to me, and dated the 12th February 1881, No. 614, and in the method of
combining the extracts or essences obtained from the said fruits and seeds with
cocoa or coffee, or like materials or their mixtures, so as to produce new and
useful compounds.
According to the first part of this Invention I first treat the fruit ceratonia
siliqua in the manner described in the Specification of my aforesaid former Letters
Patent, dated 12th February 1881, so far as disintegrating and roasting it is
concerned. I then place the fruit so treated in a suitable receptacle with water, and
boil for a sufficient time to extract the essence therefrom.. The liquor is then
strained by any suitable means from the fruit and is placed in a suitable evaporating
pan; and when it is to be used as a substitute for extract or essence of coffee,
it is boiled until, by evaporation, it becomes of the consistency required for use,
I then treat the vicia sativa or the dholl in a similar manner. To the extract or
077

page_text: essence of ceratonia siliqua I add a certain proportion of the essence of vicia sativa
or dholl, and of coffee and chicory, or by preference extract or essence of pure
coffee and chicoryprepared in the ordinarymanner,and the mixture is immediately
placed in bottles or other receptacles for sale. When required as a substitute for
extracts or essences of chocolate or cocoa, I take the ground and roasted ceratonia
siliqua (but in this case the powder is not so highly roasted), and boil and strain
as before described. I then place the strained liquor in a suitable evaporating pan
and boil for about a quarter of an hour. I then add a certain proportion, say
25% to 30% of ground cocoa nibs; this mixture is then evaporated until it
becomes of the required consistency for use. When it is required to prepare the
compound as a sweetmeat, the extract of the fruit prepared as above described is
supplimented by the addition of gum arabic, gelatine, or some other similar
substance; it is then evaporated until it becomes of the required consistency, and
when suitable flavouring is added a pleasant sweatment is obtained, useful as a
medicine in affections of the throat.
In treating the date fruit in order to render it suitable for the purposes aforesaid,
I take the dates as imported and soak for some time in cold water so as to soften
and separate the dates from each other; I then place the dates and water into a
suitable receptacle and boil until thefruit has become soft, and thelarger proportion
of the saccharine matter has been taken up by the water; I then strain off the
liquor by any suitable means so as to remove as much water as possible from the
fruit (a centrifugal machine for example); I then break up the fruit into small
pieces and place it in a revolving or some other suitable oven, adding to the dates
a certain proportion of ground, dry, or roasted ceratonia siliqua (say 25%), and a
small proportion of vicia sativa or dholl; I then roast them together until they
assume a rich brown color; I then place them in a suitable receptacle, adding the
liquor previously boiled out of the dates, and as much more water as may be
necessary, and boil until the essence is extracted; I then strain the liquor from the
fruit, and treat it the same as herein before described with regard to extracts or
essences of ceratonia siliqua used as substitutes for extracts or essences of coffee or
chocolate, and cocoa. Another method I adopt to render the date fruit suitable
for the purposes aforesaid is in the first place to disintegrate the raw fruit so as
to reduce it to the smallest possible particles; I then mix with it a certain propor-
tion of ground, dry, or roasted siliqua, say 25%, and then roast it preferably in
a revolving oven, after which I treat it in a similar manner to that last described
with reference to the fruit ceratonia seliqua in order to render it fit for the market
as a substitute for extracts or essences of coffee, chocolate, or cocoa, or prepared as
a sweetmeat.
For the purposes of making extracts or essences of date fruit, I do not confine
myself to the methods above described for preparing the fruit previously to boiling
it, or to adding to it the ceratonia seliqua, as it may be found advisable in some
cases to take the fruit roasted by itself or prepared according to any known method,
and then treat it by boiling and evaporation of the liquor as above described.

by the said Adamantius John Michael Bolanachi in the Great Seal Patent
Office on the 18th February 1882.
ADAMANTIUS JOHN MICHAEL BOLANACHI, of West Dulwich, in the County of
Surrey. "IMPROVEMENTS IN THE TREATMENT OF CERTAIN FRUITS AND SEEDS,
AND METHOD OF MAKING EXTRACTS OR ESSENCES THEREFROM AND MANUFACTURING
COMPOUNDS THEREOF."
This Invention has for its object improvements in the method of treating the
fruit scientifically known as ceratonia siliqua, and the seeds scientifically known
as vicia sativa, and that commercially known as dholl, and the date_fruit, part of
which are founded on those described in the Specification of former Letters Patent
granted to me, and dated the Twelfth day of February, One thousand eight hundred
and eighty one, and in the method of combining the extracts or essences obtained
from the said fruits and seeds with cocoa or coffee, or the like materials or their
mixtures so as to produce new and useful compounds.
According to the first part of this Invention I first treat the fruit ceratonia
siliqua in the manner described in the Specification of my aforesaid former Letters
Patent, dated the Twelfth day of February, One thousand eight hundred and
eighty one, so far as grinding or disintegrating it is concerned. I then place the
fruit so treated, and either roasted or unroasted, in a suitable receptacle with water,
and boil for a sufficient time to extract the essence therefrom. The liquor is then
strained by any suitable means from the fruit, and is placed in a suitable evapo-
rating pan, and when it is to be used as a substitute for extract or essence of.
coffee it is boiled, until by evaporation it becomes of the consistency required for
I then treat the vicia sativa or the dholl in a similar manner. To the extract
or essence of ceratonia siliqua I add a certain proportion of the essence of vicin
sativa or dholl, and of coffee and chicory, or by preference extract or essence of
pure coffee and chicory prepared in the ordinary manner, and the mixture is
immediately placed in bottles or other receptacles for sale. The following pro-
portions I have found answer well:-Ceratonia, fifty per cent.; coffee, twenty five
per cent.; chicory, twenty per cent.; and sativa or dholl, five per cent.
use.
When required as a substitute for extracts or essences of chocolate or cocoa I
take the ground ceratonia siliqua and boil and strain as before described; I then
place the strained liquor in a suitable evaporating pan and boil for about a quarter
of an hour; I then add a certain proportion (say, twenty five per cent. to thirty
per cent.) of ground cocoa nibs; this mixture is then evaporated until it becomes
of the required consistency for use when a high color is required I slightly roast
the powder before boiling it. When it is required to prepare the compound as a
sweetmeat, the extract of the fruit prepared as above described is supplimented by
the addition of gum arabic, gelatine, or some other similar substance. It is then
evaporated until it becomes of the required consistency, and when suitable
flavouring is added a pleasant sweetment is obtained, useful as a medicine in
affections of the throat.
In treating the date fruit in order to render it suitable for the purposes aforesaid
I take the date as imported and soak for some time in cold water, so as to soften
or separate the dates from each other; I then place the dates and water into a
suitable receptacle, and boil until the fruit has become soft, and the larger portion
of the saccharine matter has been taken up by the water; I then strain off the
liquor by any suitable means, so as to remove as much water as possible from the
fruit (a centrifugal machine, for example). If any water is then left I press
the same out by any suitable means, and after separating the fruit place it in a

page_text: revolving or some other suitable oven, adding to the dates a proportion of ground
dry ceratonia siliqua (say 25%) and a small proportion of vicia sativa or dholl;
I then roast them together until they assume a rich brown color; I then place
them in a suitable receptacle with as much water as may be necessary, and boil
until the essence is extracted; I then strain the liquor from the fruit and treat it
the same as herein before described with regard to extracts or essences of ceratonia
siliqua used as substitutes for extracts or essences of coffee or chocolate and cocoa,
or prepared as a sweetmeat.
I am aware that the use of the date fruit has been employed as a substitute for
coffee under processes patented by Montoison and Heuley, but it has hitherto been
found difficult to roast the fruit in consequence of the excess of saccharine matter,
and therefore flat trays only could be employed having only one layer or thickness
of the fruit, the result being an unequal roast. I therefore in my process remove
from the fruit the larger portion of the saccharine matter, and when so treated I
am enabled by adding a proportion of dried ceratonia siliqua to roast it in a
revolving oven, the parts not sticking together, and thus the whole is uniformly
roasted. For the purposes of making extracts or essences of date fruit I do not
confine myself to the methods above described of preparing the fruit previously to
boiling it or to adding to it the ceratonia siliqua, as it may be found advisable in
some cases to take the fruit roasted by itself, or prepared according to any known
method, and then treat it by boiling and evaporation of the liquor as above
described.
In making clear extracts of ceratonia siliqua, sativa, dholl, or date fruit manu-
factured as herein before described, I employ a series of receptacles having strainers
at the bottom, and into each I place a certain quantity of the ground material, not
being less than one foot thick. I then pour in water of equal weight to the
material used in the first of the series of receptacles, and when the material is
sufficiently saturated I add a further similar quantity of water, which percolates
through the material; I then test the extract, and if not of sufficient. specific
gravity I place it in the adjoining receptacle, and when percolated through I
continue the process successively until the required gravity has been obtained; I
then mix with it extracts of coffee and chicory, as before described.
I do not confine myself to the use of cold water only, as warm may be employed,
neither do I confine myself to making separate extracts, but I may mix the
ingredients before taking extracts.
Having thus described my said Invention, and the manner of carrying the same
into practical effect, I would remark in conclusion that what I claim as my
Invention is, the manufacture of compounds consisting of ceratonia siliqua or the
date fruit, the seeds vicia sativa or dholl, and coffee or cocoa, or like materials, or
their mixtures, prepared substantially in the manner herein described.
In witness whereof, I, the said Adamantius John Michael Bolanachi, have
hereunto set my hand and seal, this Eighteenth day of February, in the
year of our Lord One thousand eight hundred and eighty two.
