IMPROVE- MENTS IN THE PREPARATION OF SALT, SALTPETRE, SUGAR, AND OTHER ANTISEPTIC SUBSTANCES FOR USE IN THE PRESERVATION OF FOOD
Year: 1884

page_text: I, EDWARD SONSTADT, of Windmill Lane, Cheshunt, Herts, Fellow of the
Chemical Society do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE PREPARATION OF SALT, SALTPETRE, SUGAR, AND OTHER ANTISEPTIC
SUBSTANCES FOR USE IN THE PRESERVATION OF FOOD" to be as follows:-
My invention consists in adding calcium iodate to the antiseptics of common
domestic and general trade use in connection with food and drink, namely, to
common edible or bay salt, saltpetre, and sugar (not excluding compounded
mixtures of such substances with or without strong spices and preservative
seasonings) but not to vinegar or other acid substances.
The calcium iodate may be added according to circumstances, either in the form
of powder or in solution, and in proportion adapted to circumstances, the range of
such useful proportion being from a fraction of one per cent up to five or some-
what more per cent of the iodate to the quantity taken of salt or other preservative
substance.
Sugar may be regarded either as an antiseptic, or as itself a food, or partly one
and partly the other. In adding the iodate to or in connection with sugar used
antiseptically (e.g. to condensed milk, etc.) a small proportion is sufficient. The
application of the iodate I further discover has a beneficial action in removing the
suell possessed by some sugars, hence I propose to utilize such property by
applying the iodate to sugar, either at an early or late stage of its refinement or of
its manufacture.
For some purposes I enhance the solubility of calcium iodate in water by
dissolving the iodate in solutions containing a neutral sodium or potassium citrate.

Society, do hereby declare the nature of my invention for "IMPROVEMENTS IN THE
PREPARATION OF SALT, SALTPETRE, SUGAR, AND OTHER ANTISEPTIC SUBSTANCES
FOR USE IN THE PRESERVATION OF FOOD and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
"
My invention consists in adding calcium iodate to the antiseptics of common
domestic and general trade use in connection with food and drink; namely, to
common or bay salt, saltpetre, and sugar, as well as to mixtures of any of these
with spices and preservative seasonings, but not to vinegar or to other acid
substances. The calcium iodate may be added in powder or in solution according
to circumstances, and in proportion from a fraction of one per cent, up to five or
somewhat more per cent. of the iodate to the quantity taken of salt or other
preservative substance, as may be required.
Sugar may be regarded either as an antiseptic, or as itself a food, or as partly-
one and partly the other. In adding calcium iodate to or in connection with sugar
used antiseptically, as for example in the case of condensed milk, a small proportion,
as say a grain of the iodate to a pound weight of the condensed milk, is sufficient,
though a larger proportion may be introduced without occasioning inconvenience
in its use.
The application of calcium iodate has a beneficial effect in removing
the odour belonging to some kinds of sugar, which property I propose to utilise by
applying calcium iodate to sugar, either at an early or late stage of its refinement
or of its manufacture.
When it is desired to use for the purposes of the invention calcium iodate in
aqueous solution, the solubility of the iodate may be increased by addition of a
neutral sodium or potassium citrate.
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 application of calcium iodate in the preparation of salt, saltpetre,
sugar, and other antiseptic substances for use in the preparation of food, as herein
set forth.
