I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E. of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street, Man-
chester, both in the County of Lancaster and 323 High Holborn in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the employment, in yeast and spirit manu-
facturing, of a large number of substances, rich in proteine, which hitherto have
not been utilised in these industries.
These substances are raw and dried slaughter house refuse, such as flesh albumen,
meat meal, dried blood meal, leather parings; raw or dried fish refuse, such as
fish guano, and animal excrements; refuse from the manufacture of vegetable oils
by pressure or extraction, both in the form of cakes, especially linseed, rape,
ground nut, sunflower, poppy, mustard, hemp, Niger cottonseed, palm kernels,
etcetera, as well as in that of meal.
These substances contain the proteine mainly in an indigestible form, and, in
order to be employed in the production of yeast, the albuminous substances must
therefore be peptonised or be converted into a form capable of being assimilated by
the yeast. This may be effected by treating these substances under pressure with
or without adding thereto organic or inorganic acids, or by peptonising them at a
low temperature, between 300 and 50 degrees centigrade, by the addition of pepsin,
malt, malt extract, lactic acid, etcetera.
The extracts rich in nitrogen, which are produced in this manner, may either be
added to the usual mash or wort in yeast or spirit manufacturing, or be mixed with
saccharine solutions or syrups, whereupon the mixtures thus obtained are fermented
in the usual manner.

A communication by OSCAR EMIL NYCANDER, of 10, Am Circus, Berlin, in the

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E. of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street, Manchester,
both in the County of Lancaster, and 323 High Holborn in the County of
Middlesex, Civil Engineer, 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 the employment, in yeast and spirit manu-
facturing, of a large number of substances, rich in proteine, which hitherto have
not been utilised in these industries.

page_text: These substances are raw and dried slaughter house refuse, such as flesh albumen,
meat meal, dried blood meal, leather parings; raw or dried fish refuse, such as
fish guano, and animal excrements; refuse from the manufacture of vegetable oils
by pressure or extraction, both in the form of cakes, especially linseed, rape,
ground nut, sunflower, poppy, mustard, hemp, Niger cottonseed, palm kernels,
etcetera, as well as in that of meal.
These substances contain the proteine mainly in an indigestible form, and, in
order to be employed in the production of yeast, the albuminous substances must
therefore be peptonised or be converted into a form capable of being assimilated
by the yeast. This may be effected by treating these substances under pressure
with the addition of organic or inorganic acids, or by peptonising them at a low
temperature, between 30 and 50 degrees centigrade by the addition of pepsin,
malt, malt extract, lactic acid, etcetera, or the substances may be treated by pressure
alone.
The extracts rich in nitrogen, which are produced in this manner, may either be
added to the usual mash or wort in yeast or spirit manufacturing, or be mixed with
saccharine solutions or syrups, whereupon the mixtures thus obtained are fermented
in the usual manner.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
The improvements in, or in the preparation of, extracts for use in the manu-
facture of yeast and spirit, substantially as herein before described, which consist in
the employment therefor of the following substances, namely, raw and dried
slaughterhouse refuse, such as flesh albumen, meat meal, dried blood meal, leather
refuse; raw or dried fish refuse, such as fish guano, animal excrement; spent
material from vegetable oil manufactures by pressure or extraction, both in the
form of cakes, more particularly of linseed, rape, ground nut, sunflower, poppy,
mustard, hemp, Niger cottonseed, palm kernels, etcetera, as well as that of meal.
