PROVISIONAL SPECIFICATION.
Improvements in or relating to the Preparation of Substitutes for
Coffee.
I, HEINRICH TRILLICH, Chemist, of 20 Mühldorfstrasse Munich in the Empire
of Germany do hereby declare the nature of this invention to be as follows:-
This invention relates to the process of making a substitute for coffee, that is to
say a material for use in the preparation of a beverage resembling coffee, in
which unroasted cereals or malt is treated with an aqueous solution derived from
unroasted coffee or waste products thereof.
"
The purpose of the present improvements on the aforesaid process is to improve
the flavour and aroma as well as the alcoloidal qualities of the product.
With this object the invention consists in giving to the malt or cereals chosen for
the basis of the product a preliminary treatment with an aqueous solution or
extract of cocoa shells, kola nut, (fruit or leaves) matté leaves, tea, or generally
with any solution containing caffeine. After the malt or cereal has been impregnated
with these substances or any of them in addition to or in substitution of the coffee
extract before mentioned, it is roasted and the product will be found to contain
a small quantity of alcaloidal matter giving a flavour which may be varied
according to the choice or proportion of the ingredients of the extract.

COMPLETE SPECIFICATION.
Improvements in or relating to the Preparation of Substitutes for
Coffee.
I, HEINRICH TRILLICH, Chemist, of 20 Mühldorfstrasse, Munich, in the Empire
of Germany, 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 process of making a substitute for coffee, that is to
Bay, a material for use in the preparation of a beverage resembling coffee, in
which unroasted cereals or malt is treated with an aqueous solution derived from
unroasted coffee or waste products thereof.
The purpose of the present improvements on the aforesaid process is to improve
the flavour and aroma as well as the alkaloidal qualities of the product.
With this object the invention consists in giving to the malt or cereals chosen for
the basis of the product a preliminary treatment with an aqueous solution or
extract of cocoa shells, kola nut (fruit or leaves) matté leaves, tea, or generally
with any solution containing caffeine.
After the malt or cereal has been impregnated with these substances or any
of them, in addition to or in substitution of the coffee extract before mentioned,
it is roasted and the product will be found to contain a small quantity of
alkaloidal matter giving a flavour which may be varied according to the choice
or proportion of the ingredients of the extract.

page_text: Amongst the materials to which this process may be applied there may be
mentioned; barley, wheat, rye maize, millet, rice, durrah etc., chickory, figs, pears
and leguminous matters in general.
The form of the cereals may be chosen in whole grains, hulled grains or grains
in coarsely or finely disintegrated condition.
As to the strength of the caffeine solution and to the proportion in which it
is to be applied, these should be according to experiments and to the taste to be
obtained in the artificial coffee various proportions and according to the
construction of the roasting apparatus and to the ultimate degree of heat applied
to the substances under treatment.
Thus, for instance in using barley, a very successful result is obtained where
100 pounds (German weight) of grain is treated with 500 grams of extract of
coffee shells dissolved in 3 liters of water.
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.
An improved method of producing coffee substitutes from cereals, malt or the
like, consisting in impregnating unroasted cereals or malt, with a caffeine containing
extract or a caffeine containing solution, aqueous extracts of unroasted cocoa or
cocoa shells, kola nut (fruit or leaves) leaves of the matté plant, tea plant, or
similar produce, other than or in conjunction with coffee refuse or the like as
heretofore used, substantially as set forth.
