AN IMPROVED PROCESS FOR PRESERVING MILK OR CREAM
Year: 1884

page_text: 'I EDUARD LOEFLUND, of Stuttgart, in the Kingdom of Wurtemberg and
Empire of Germany, Manufacturer of Malt Extract, do hereby declare the nature
of my Invention for AN IMPROVED PROCESS FOR PRESERVING MILK OR CREAM
to be as follows :-
My Invention relates to an improved process for preserving milk or cream by
the addition of unfermented concentrated extract of malted wheat, barley or oats,
or any combination thereof, as a food for infants and invalids.
I take say 100 liters of fresh cow's milk, with all the cream or with only a
certain proportion thereof, and warm in an open pan, preferably heated by steam,
to a temperature of about 90° "centigrade,” I then add about 20 kilogrammes of
unfermented concentrated extract made from malted wheat, barley or oats, or any
combination thereof; when the extract is properly dissolved and mixed with the
milk and the fluid has become uniform and smooth, I introduce it into a vacuum
apparatus and condense at a temperature not exceeding 50° "centigrade," until
1 bring it into a mass of the consistency of soft butter, which is the case when its
weight is reduced to about 40 kilogrammes. The process being thus completed
I put up the product in tins or vessels hermetically closed by soldering or
otherwise.
In preparing the malt extract, the principle is to be observed that all the starch
of the malted cereals should be converted into dextrine and sugar by the action of
the diastase; also, that the natural acid of the malt solution is to be neutralized
by the addition of a small quantity of carbonate of potassium or of sodium or an
equivalent.

Empire of Germany, Manufacturer of Malt Extract do hereby declare the nature
of my Invention for "AN IMPROVED PROCESS FOR PRESERVING MILK OR
CREAM" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
My Invention relates to an improved process for preserving milk or cream
without cane sugar or chemicals, by the addition of unfermented concentrated
extract of malted wheat, barley or oats, or any combination thereof, as a food for
infants and invalids.
The method of proceeding is as follows:-
I take say 100 litres of fresh cow's milk, with all the cream or with only a
certain proportion thereof, and warm in an open pan, preferably heated by steam,
to a temperature of about 90 to 95 degrees "centigrade," I then add about
20 kilogrammes of unfermented concentrated extract made from inalted wheat,
barley or oats, or any combination thereof; when the extract is properly dissolved
and mixed with the milk and the fluid has become uniform and smooth, I introduce
it into a vacuum apparatus and condense at a temperature not exceeding
50° "centigrade" until I bring it into a mass of the consistency of soft butter,
which is the case when its weight is reduced to about 40 kilogrammes. The
process being thus completed I put up the product in tins or vessels hermetically
closed by soldering, or otherwise, which are then to be put into boiling water for a
few minutes.
In preparing the malt extract the principle is to be observed that all the starch
of the malted cereals should be converted into maltose by the action of the diastase,
also, that the natural acid of the malt solution is to be neutralized by the
addition of a small quantity of carbonate of potassium or of sodium, or any
equivalent.
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:
The preservation of milk or cream without cane sugar or chemicals according to
the following process:-
To heat the milk or cream nearly to the boiling point, then to add an unfer-
mented concentrated extract of malted cereals, the natural acid of which has
previously been neutralized, then to condense the fluid in a vacuum apparatus to
the consistency of soft butter and to fill the product into tins hermetically closed
by soldering or otherwise, which are then to be kept in boiling water for a few
minutes.
