Improvements in the Preparation of Peptone Extracts, and in the
Application of the same to Various Useful Purposes.
We, MORRIS PAUL HATSCHEK, of 27 Bedford Place, London W.C., Chemical
Engineer, GEORGE ARCHIBALD CLOWES, of Needham Market, in the County of
Suffolk, Maltster, and LAWRENCE BRIANT, of 24 Holborn Viaduct, London, E.C.,
Analytical Chemist, do hereby declare the nature of our said invention to be as
follows:-
:-
This invention relates to similar subject matters to those comprised in certain
Letters Patent granted to the said Morris Paul Hatschek, dated 5th March 1888,
No. 3363; and 17th December 1888 No. 18,399; and its object is to improve and
extend the preparation and application of the extracts therein mentioned, and of
other preparations of a similar nature.
may
The extract of malto-peptone (formerly called malto-peptine)
be prepared
by the evaporation of a liquid obtained by the extraction of malt culms, in the
manner described in the before mentioned Specifications, or with or without
antiseptics, or with various proportions of water; or with water alone, either hot or
Cold; although we prefer the original method described in the said Specifications.
This extract is used for fermenting purposes, viz:-for feeding yeast and increasing
its activity and power of reproduction; either alone or mixed with saccharine,
dextrine, maltose glucose, cane sugar, &c.; for adding to brewers' or distillers'
fermentation; and to bakers' ferment or sponges; and for making buns; rolls; &c.,
as well as for direct addition to bread, cake, biscuits, chocolate, &c., and other
kinds of solid or liquid foods, to increase their nutritive qualities and values.
The extract may also advantageously be used either alone or mixed with oil,
glycerine, &c. as a substitute for yolks of eggs in tanning and dressing leather, as
described in 18399. It may furtlier be used for direct nutritive purposes, in
pharmaceutical preparations either by itself or admixed with cod-liver oil or malt
extract, and similar substances. Meat peptone may also be, used for a similar
purpose, although it is not so suitable, and our invention includes the use of
vegetable or meat peptone of any description whatever for the purposes above
described.

Analytical Chemist, do hereby declare the nature of said 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 similar subject matters to those comprised in certain

No. 3363; and 17th Decr. 1888, No. 18,399; and its object is to improve and

page_text: extend the preparation and application of the extracts therein mentioned and of
other preparations of a similar nature.
The extract of malto-peptone (formerly called malto-peptine) may be prepared
by the evaporation of a liquid obtained by the extraction of malt culms, or other
vegetable substances containing nitrogen, in the manner described in the before
mentioned Specifications, or with or without antiseptics, or with various proportions
of water, or with water alone, either hot or cold; although we prefer the original
method described in the said Specifications. This extract is used for fermenting
purposes, riz. for feeding yeast and increasing its activity and power of repro-
duction either alone or mixed with saccharine, dextrine, maltose, glucose, cane
sugar, &c. for adding to brewers' or distillers' fermentation, and to bakers'
ferment or sponges; and for making buns, rolls, &c., as well as for direct addition
to bread, cake, biscuits, chocolate, &c., and other kinds of solid or liquid foods, to
increase their nutritive qualities and values.
The extract may also advantageously be used either alone or mixed with oil,
glycerine, &c. as a substitute for yolks of eggs in tanning and dressing leather, as
described in No. 18,39988.
It may further be used for direct nutritive purposes in pharmaceutical pre-
parations, either by itself or admixed with cod-liver oil or malt extract, and
analogous substances.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we wish it to be understood
that we do not claim the addition of meat peptone to articles of food and pharma-
ceutical preparations, although the same was mentioned in our Provisional Specifi-
cation; and we declare that what we claim is:
The improvements in the preparation of peptone extracts, and in the application
of the same to various useful purposes, substantially as herein before described.
