We CHARLES WILLIAM NAPIER WALLACE of 37 St. George's Road Southwark
and CHARLES JOHN HARRISON BARRY of 11 Champion Terrace, Grove Lane,
Camberwell both, in the County of Surrey, Analytical Chemists do hereby declare the
nature of this invention to be as follows:-
The invention has for its object improvements in the manufacture of caramel
whereby a superior article is obtained from any class of sugar, by a very economical
process.
For this purpose we treat raw or other sugar with any suitable acid, preferably
sulphuric diluted sufficiently to avoid carbonization of the sugar submitting the same
to heat as may be required, after allowing the compound to stand a sufficient time,
which will vary according to the character of sugar used we neutralize it with any
suitable alkali slightly in excess preferably using ammonic carbonate.
After the neutralization has been effected we increase the heat to about 212°
Fahrenheit until the required consistency is obtained depending upon whether a
liquid or solid product is required.

page_text: We CHARLES WILLIAM NAPIER WALLACE of 37 St. George's Road Southwark
and CHARLES JOHN HARRISON BARRY of 11 Champion Terrace, Grove Lane,
Camberwell both in the County of Surrey Analytical Chemists 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:
The invention has for its object improvements in the manufacture of Caramel,
whereby a superior article is obtained from any class of sugar by a very economical
process inasmuch as there is no waste of sugar in carrying our improved process
into effect.
For this purpose we treat raw or other sugar with any suitable acid, preferably
using sulphuric acid, which we dilute sufficiently to avoid carbonization of the sugar,
we submit the compound to heat as may be required and after allowing the compound
to stand a sufficient time, which will vary according to the character of sugar used,
we neutralize it with any suitable alkali using the same slightly in excess and
preferably employing Carbonate of Soda on account of its cheapness.
The following is an illustration of the mode in which we carry our invention into
effect.
وو
We dissolve 2 Cwt of refined or partially refined " cane sugar in 3 gallons of
water, we then add 4 pints of Sulphuric acid diluted with one gallon of water and
we digest the mixture from 2 to 3 hours in a water jacketted vessel at a temperature
of about 200° Fahrenheit.
We then allow the mixture to stand for a period of from 2 to 3 hours after which
we neutralize the mass with carbonate of soda slightly in excess so as to leave the
Caramel slightly alkaline.
After the neutralization has been effected we submit the compound to a suitable
temperature in order to complete the change and to obtain the required consistency,
which will depend upon whether a more or less liquid or solid product is required.
The temperature required is from about 212° Fahrenheit and upwards which is
continued as long as is necessary to obtain the required result.
In treating different classes of sugar the proportion of acid employed will be
slightly varied, for instance when treating glucose a smaller quantity of acid will be
necessary than when treating "cane" sugar.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is:-
The manufacture of Caromel by treating sugar with dilute acid and heat, then after
allowing the same to stand neutralizing the same with an alkali and evaporating it to
the consistency desired substantially as herein described.
