PROVISIONAL SPECIFICATION.
Improvements in the Manufacture from _Starch_or Starchy
Substances of a Material suitable for Use in Brewing and
for other purposes.
I, CHARLES HENRY MEYER of Commercial Road, Shepton Mallet in the
County of Somerset, Brewer, do hereby declare the nature of this invention to
be as follows:-
The object of my invention is to manufacture from starch or starchy substances
a material suitable for use in brewing and for other purposes.
I take a farinaceous or starchy substance, preferably sago flour, in as pure a
state as practicable, and I submit it to the action of chlorine or of chloride of
lime in solution of sufficient strength to render the starch readily soluble. I then
remove the chlorine or chloride of lime and this can be conveniently effected by
running off the solution after time has been allowed to settle and then washing the
starch by repeated applications of cold water. The starch is then gelatinized or
rendered soluble by mixing it with water and raising it to a boiling temperature
preferably under slight pressure. The solution is then allowed to cool and malt
extract or other diastase is added to it whereby the starch is converted into a more
or less pure dextrin. The unconverted part of the starch should be separated by
filtration or otherwise and a small quantity of a suitable clarifying. material may
be added to the dextrinous solution so as to remove any clouding matter.
The dextrinous solution may be more or less condensed before being put on the
market or it may be made into a dry powder which may be effected by raising it
to boiling point and then passing it over steam-heated or other hot surfaces.
Dated this 18th day of January 1894.

COMPLETE SPECIFICATION.
Improvements in the Manufacture from Starch or Starchy
Substances of a Material suitable for Use in Brewing and
for other purposes.
I, CHARLES HENRY MEYER of Commercial Road, Shepton Mallet in the
County of Somerset, 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:-
The object of my invention is to manufacture from starch or starchy substances
a material suitable for use in brewing and for other purposes.
I take a farinaceous or starchy substance, preferably sago, flour in as pure a state
as practicable and I submit it to the action of chlorine or of chloride of lime in
solution of sufficient strength to render the starch readily soluble. A suitable
strength is obtained by the addition of 1 pound of chloride of lime to about every
5 gallons of water. I then remove the chlorine or chloride of lime and this can
be conveniently effected by running off the solution after time has been allowed to
settle and then washing the starch by repeated applications of cold water. The
starch is then gelatinized or rendered soluble by mixing it with water and raising
it to a boiling temperature preferably under slight pressure. The solution is then

page_text: allowed to cool down to a temperature of about 150° to 160° Fahrenheit and malt
extract or other diastase is added to it, whereby the starch is converted into a more
or less pure dextrin. The solution is raised to boiling point immediately the
conversion is effected so as to kill the diastase. The proportion of malt extract
employed may be considerably varied, it being understood that the more that is
used the quicker will the conversion be effected and the better will be the flavor of
the product obtained. A suitable proportion is about 170 pounds to a ton of the
starch or material under treatment. A small quantity of a suitable clarifying
material may be added to the solution either before or after the conversion so as to
remove any clouding matter; if added after the conversion the solution should be
again raised to boiling point. The unconverted residue of the starch should be
separated by filtration or otherwise.
The dextrinous solution may be more or less concentrated by means of vacuum
pans or otherwise before being put on the market for sale as a material for use in
brewing or other purposes or it may be made into a dry powder, and this can
conveniently be effected by raising it to boiling point and then passing it over
steam-heated or other hot surfaces.
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 :-
A-
✓ The process hereinbefore described of treating starch or starchy substances in
order to manufacture a material suitable for use in brewing or for other purposes,
which process consists in submitting the starch or other substance to the action of
chlorine or chloride of lime, then removing the chlorine or chloride of lime, then
gelatinizing or rendering soluble the starch or other substance and then adding a
diastase thereto whereby the starch is converted into a dextrinous material, all
substantially as set forth.
