COMPLETE SPECIFICATION
A Composition for Admixture with the Flour of Wheat, Rice, or
other Grains, to Restore to such Flour the Lost Natural Mineral
or Saline Food Substances or their Equivalents.
I, GEORGE WEDDELL, 20, West Grainger Street, Newcastle-on-Tyne, Chemist,
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 has reference to a composition to be added to the flour of wheat,
rice or other grain or grains, its object being to restore to such flour the natural
mineral or saline food substances or equivalents thereof, such as lime salts,
phosphates, iron and the like, which, as bone-forming material and as furnishing
the salts of the blood, are so valuable, and yet which are unavoidably removed
with the outer covering or bran, and lost during the process of milling. By the
restoration of the natural or substitution of equivalent mineral substances to such
flour as has been deprived of its bran or outer covering and consequently of its
nutritive salts, phosphates, iron etc., I can not only render it again as rich in such
mineral matter, but I can either diminish or increase the proportion of any or all
of the said substances to suit different requirements.
The mineral or saline food substances which I add to the flour are as follows:-
Calcium phosphate, calcium carbonate, calcium fluoride, magnesium phosphate,
magnesium carbonate, sodium phosphate, potassium phosphate, and phosphate and
oxide of iron.
The ingredients and their proportions which I prefer for general purposes are
as follows:-
Calcium phosphate
Magnesium
"
Potassium
"
Sodium
300 parts.
136 parts.
50 parts.
182 parts.
18 parts.
Calcium fluoride
These I mix intimately by triturating in a mortar or by any other well known
mechanical means and thus produce a compound which I add directly to the flour.
In some cases I slightly vary or alter the proportions of the ingredients and
sometimes omit the potassium phosphate.
The proportions in which I use the other ingredients when I wish to add them
to the above mentioned general composition are as follows.
Calcium carbonate
Magnesium carbonate
Phosphate of iron
Oxide of iron

The proportion of the composition generally added to the flour is one and a half
per centum (1 per cent.) but I increase or diminish the amount to suit different
requirements. For example, in employing the flour for foods for infants or weakly
children I might increase the amount of the composition to be added to the flour
in any proportion up to four per centum (4 per cent.).
The composition is incorporated with the flour by means of an ordinary mixing
unted her hand on other suitable nower

page_text: The flour is sometimes dried or partly cooked either before or after the addition
of the composition.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I do declare that what I
claim is :-
1.
!
(1) The admixture with the flour of wheat, rice or other grains of the chemical
or mineral ingredients substantially as herein before described.,
(2.) The composition for admixture and in admixture with the flour of wheat,
rice or other grains of the ingredients and in or about the proportions herein
specified.
