An Invention for the Preparation of Tonic Foods.
HERBERT EDWARDS WRIGHT Southend House Wickwar Gloucestershire Brewer
do hereby declare the nature of this invention to be as follows:-
The addition or employment of salts of iron, particularly phosphate of iron and of
phosphates of lime, soda or potash either separately or conjointly in the preparation
for sale of solid & semi-solid articles of food particularly of biscuits cakes &
chocolate.
HERBERT EDWARDS WRIGHT Southend House, Wickwar Gloucestershire M.A.
(Trin. Coll. Camb.), Brewer, 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:-
I take an iron salt by preference iron tartarate, calcium lactophosphate & sodium &
potassium phosphates all soluble in such proportions that the iron base shall be equal
in quantity to each of the other bases but usually in the proportion of 2: 1, such
proportion however being variable to any extent which may seem desirable from time
to time, & with the iron salt I thoroughly incorporate a portion of pepsin or papain,
& these soluble salts together with the pepsin or papain I incorporate either with the
paste of the cacao-bean used in the manufacture therefrom of chocolate & form the
combined matters into cakes tablets or any other convenient form or I incorporate
them with already prepared chocolate, reforming the said combined matters into
tablets or cakes which, if necessary, shall be dried by gentle heat or over calcic
chloride sulphuric acid or otherwise, or made into preparations more or less resembling
chocolate creams or caramels. Or I incorporate the salts & the pepsin or papain with
the pulp of fruit in the dried or natural state such pulp to include the softer
parts of tamarinds or figs & I use the compound in combination either with chocolate
or some other edible matter or alone. Or I incorporate the salts with the pepsin or
papain with malt-extract reduced by evaporation to a semi-solid consistency, or I
treat the malt extract with the pepsin or papain at some earlier stage & 1 use the
mixture either alone or in combination with chocolate or any other edible substances.
Or I incorporate the above salts either with or without pepsin or papain with flour
either of wheat or of any other cereal or of malt, or with any other of the materials
used in the manufacture of biscuits or cakes or with any substances for instance
dextrin or sugar or white of egg usable as a glaze or with chocolate for
combination with such biscuits either as an integral part or otherwise.

page_text: And I claim that the specifying of undissolved but soluble salts as used in any
of the above preparations may be taken to include the use of them in solution &
that, although iron tartarate & calcium lactophosphate are specially mentioned as
used, I may be allowed for the purposes set forth in this specification the exclusive
use of all other soluble salts of iron or of the reduced iron of the British
Pharmacopeia or of any insoluble salts if due means be taken [u] to render them
soluble or [3] to bring them into a state of potential solubility as for example in
the first case [a] ferrous or ferric phosphate dissolved in an excess of citric acid
such acid being either retained or precipitated as citrate of lime or the same salts
dissolved in dilute hydrochloric acid with addition of citric acid, the HCl being
.afterwards neutralised with carbonate of soda with formation of sodium chloride or of
calcic phosphate dissolved in phosphoric acid or a solution of any organic acid :, &
in the second case [3] the intimate admixture with such salt of such proportion of
an organic acid as shall assure prompt assimilation by the digestive system.
And I further claim that the use of pepsin or papain as above indicated,
important as it is & for which special protection is asked, may not be held essential
in the sense that their omission shall justify any infringement of rights granted in
pursuance of this application.
The quantities of the iron preparations or salts & of other salts preferably used
in certain typical articles of food are-to such quantity of flour & other ingredients
as may form a biscuit weighing 120 grains approximately, or to 180 grains of the
prepared or powdered contents of the cacao bean, but to 90 grains of the said cacao
powder if it be mixed with other edible matters named above, 10 grains of tartarated
iron, 2 grains of reduced iron, 4 grains of iron phosphate, 2 grains of each or
either of the phosphates of lime, soda or potash & grain of pepsin or papain.
But such quantities are variable to any extent that may seem from time to time
desirable.
Having now particularly described & ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what
I claim is
1. The use of salts of iron or reduced iron & phosphates of lime potash & soda in
combination with solid or semi-solid articles of food.
2. The use of pepsin or papain in conjunction with salts or the named preparations
of iron, soda, lime or potash."
Dated this Second day of January 1897.
