IMPROVEMENTS IN BAKING POWDERS
Year: 1885

page_text: I ALFRED GEORGE BROOKES, of the firm of Wm Brookes & Son, of 55 &
56 Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents do hereby declare the nature of my invention, for IMPROVEMENTS IN
BAKING POWDERS to be as follows:-
The invention has for its object, first, to produce a baking powder, consisting of
an acid lactate, combined with the carbonates or bicarbonates of the alkaline
earths and, secondly, to provide a means for preventing the change and reaction
liable to take place when an acid lactate is mixed with a carbonate or bicarbonate
of an alkali, or alkaline earth, to form a baking powder.
In carrying out the first part.of the invention, I take, say, 434 parts (by weight)
of the acid lactate of calcium, and mix therewith 100 parts (by weight) of the
carbonate of calcium, or a chemically equivalent part of carbonated magnesia; to
this I add a proper dividing agent such as starch, dry and powdered, or rice-flour,
to prevent change and loss of strength, using preferably of such dividing agent,
about 25 per centum of the foregoing mixture, and thus produce a very effective
baking powder. In order to further guard against reaction, and chemical change,
when said baking power is to be kept for a considerable length of time before
using, I protect the mixture by means of an oleaginous material, in addition to the
dividing agent already named.
In carrying out this second part of the invention, I first take, say 434 parts (by
weight) of dried acid calcium, lactate, and mix with it about 33 parts (by weight)
of lard, tallow, or other suitable oleaginous or fatty material, (preferably by
repeatedly passing them through a fine sieve), and then mix there with the before
named proportions of the carbonate of calcium (or magnesia), and the dividing
agent, which, has the effect of enabling the baking powder to be kept for an
indefinite time, without change or reaction, as stated.

page_text: The second part of the invention is equally well adapted for use with a baking
powder consisting of an acid lactate mixed with any alkaline carbonate or
bicarbonate as it is with the special baking powder which forms the first part
of the present invention. When this is applied to a baking powder containing a
carbonate or bicarbonate of an alkali, part of the oleaginous material may be first
thoroughly mixed with said alkaline carbonate or bicarbonate, if preferred, and, if
desired, other acid lactates than that of calcium may be employed.

I ALFRED GEORGE BROOKES of the firm of Wm Brookes & Son of, 55 &
56 Chancery Lane in the County of Middlesex, Fellow of the Institute of Patent
Agents 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 for its object, first, to produce a baking powder, consisting of
an acid lactate, combined with the carbonates or bicarbonates of the alkaline
earths: and, secondly, to provide a means for preventing the change and reaction
liable to take place when an acid lactate is mixed with a carbonate or bicarbonate
of an alkali, or alkaline earth, to form a baking powder.
In carrying out the first part of the invention I take, say, 434 parts (by weight)
of the acid lactate of calcium, and mix therewith 100 parts (by weight) of the
carbonate of calcium, or a chemically equivalent part of carbonated magnesia; to
this I add a proper dividing agent such as starch, dry and powdered, or rice-flour,
to prevent change and loss of strength, using preferably, of such dividing agent,
about 25 per centum of the foregoing mixture, and thus produce a very effective
baking powder. In order to further guard against reaction, and chemical change,
when said baking powder is to be kept for a considerable length of time before
using, I protect the mixture by means of an oleaginous material, in addition to the
dividing agent already named.
In carrying out this second part of the invention, I first take, say 434 parts
(by weight) of dried acid calcium lactate, and mix with it about 33. parts (by
weight) of lard, tallow, or other suitable oleaginous or fatty material, (preferably
by repeatedly passing them through a fine sieve), and then mix therewith the

page_text: beforenamed proportions of the carbonate of calcium (or magnesia), and the
dividing agent, which has the effect of enabling the baking powder to be kept
for an indefinite time, without change or reaction, as stated.
The second part of the invention is equally well adapted for use with a baking
powder consisting of an acid lactate mixed with any alkaline carbonate or
bicarbonate as it is with the special baking powder which forms the first part
of the present invention. When this is applied to a baking powder containing a
carbonate or bicarbonate of an alkali, part of the oleaginous material may be first
thoroughly mixed with said alkaline carbonate or bicarbonate, if preferred, and, if
desired, other acid lactates than that of calcium may be employed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A baking powder, or bread-raising mixture, consisting of an acid lactate
combined with the carbonate or bicarbonates of the alkaline earths.
2. An acid lactate baking powder, in which the separate salts are protected from
reaction during storage by the presence of an oleaginous or fatty material.
