Year: 1879

page_text: LETTERS PATENT to Adrianus Pieter van de Water, of Haarlem, in the Kingdom
of Holland, Wine Merchant, for the Invention of "AN IMPROVEMENT IN
TREATING CHEESE IN ORDER TO PRESERVE THE SAME."
PROVISIONAL SPECIFICATION left by the said Adrianus Pieter van de Water
at the Office of the Commissioners of Patents on the 20th October 1879.
ADRIANUS PIETER VAN DE WATER, of Haarlem, in the Kingdom of Holland,
Wine Merchant. "AN IMPROVEMENT IN TREATING CHEESE IN ORDER TO PRESERVE
THE SAME."
My Invention relates to an improvement in treating cheese in order to preserve
the same, and is especially applicable to those cheese which have a skin, rind, or
crust.
In carrying my Invention into effect, I first wash the cheese after they are taken
from the salt tub in a solution composed of rectified pyroligneous acid and water,
and I then dry the cheese with a cloth.
This solution tends also to strengthen the skin or rind of the cheese, and thus
the cheese is sooner fit for the market and for exportation than heretofore.
In cases where cheese should have been nibbled by rats or mice, or attacked by
worms or other insects, the parts affected must be washed with the above named
solution, and a fresh crust, skin, or rind, will be formed again. Also when cheese
has become mouldy, if this solution be applied thereto it will entirely remove the
mould therefrom.

ADRIANUS PIETER VAN DE WATER, of Haarlem, in the Kingdom of Holland,
Wine Merchant. "AN IMPROVEMENT IN TREATING CHEESE IN ORDER TO PRESERVE
THE SAME."
My Invention relates to an improvement in treating cheese in order to preserve
the same, and it is especially applicable to those cheese which have a skin, rind, or
crust.
In carrying my Invention into effect, I first wash the cheese in cold water on
their coming from the salt-tub, and I then treat them with a solution.composed of
rectified pyroligneous acid and water, and I dry them afterwards with a cloth;
but should the cheese be only pressed, then on their removal from the press I treat
them directly with the said solution and then dry them.
Different kinds of cheese require different strengths of the solution, but for newly
made cheese the following proportions will be found to answer the purpose, viz.,
1 part rectified pyroligneous acid to 20 parts of water.
The washing of newly made cheese must be effected four times, one after the
other, with an interval of four days between each washing, after that as soon and
as often as they begin to turn mouldy they must be washed with the solution.
Should cheese become decayed or decomposed inwardly, and show outward signs
thereof, the decayed part or parts or place or places must be touched with a brush
dipped in pure rectified pyroligneous acid, and then washed with the above named
solution.
For old cheese with mites, worms, or mould, a solution of 1 part rectified
pyroligneous acid to 10 parts water will be found serviceable.
In cases where cheese should have been nibbled by rats or mice, or attacked by
insects, the part or parts so affected should be washed with the above named
solution, and it will be found that in a very short space of time a fresh skin, rind,
cor crust will be again formed.
Decayed or decomposed cheese can be also preserved against further destruction
by washing the same in a strong preparation of the above named solution.
This solution tends also to strengthen the skin, crust, or rind of the cheese, and
thus the cheese are sooner fit for the market and for exportation than heretofore.
Cheese so treated can be preserved against outward injuries for any length of
time, and the weight thereof maintained, and scraping is rendered unnecessary.
Having now described the nature of the said Invention and in what manner the
same may be performed, I declare that I claim,-
Treating cheese by washing it in a solution composed of rectified pyroligneous
acid and water in or about the proportions mentioned, and in the manner described
for the purposes set forth.
In witness whereof, I, the said Adrianus Pieter Van de Water have hereunto
set my hand and seal, this Fourteenth day of April, in the year One
. thousand eight hundred and eighty. ·
