IMPROVEMENTS IN THE TREATMENT OF THE LUPINUS PLANT (LUPINE) TO ADAPT IT FOR USE AS FOOD FOR CATTLE
Year: 1884

page_text: I, EMIL CAPITAINE of 89 Chancery Lane, in the County of Middlesex, Engineer,
do hereby declare the nature of the said invention for "IMPROVEMENTS IN THE
TREATMENT OF THE LUPINUS PLANT (LUPINE) TO ADAPT IT FOR USE AS FOOD FOR
CATTLE" to be as follows:-
This invention consists in bringing the lupinus plant into such a state that upon
its lixiviation with hot water the albuminous matter contained therein no further
coagulates, a novel result that is not obtained by any of the processes hitherto
employed.
For this purpose the lupinus is dried by heat so that the same shall not attain a
higher temperature than 70. degrees Celsius. Hereupon the albuminous matter
passes over into a state which preserves it from coagulation when, for the purpose of
extracting its bitter ingredient, it is placed in water of which the temperature
ranges between 65 and 85 degrees Celsius. If the lupinus be placed in water of a
temperature below 65 degrees Celsius a considerable portion of the albuminous
matter is washed out and so lost to the lupinus. If the lupinus dried in the
aforesaid manner be placed in water of over 85 degrees Celsius the albuminous
matter coagulates as in the case of the undried material when a very large
percentage of the same would pass over into an insoluble state and be thereby lost
in so far as regards feeding purposes. If lupinus be used that has not been dried
in the aforesaid manner and if the temperature of the water bath be higher than
65 degrees Celsius, the albuminous matter coagulates, and is in part insoluble, whilst
the lupinus dried in accordance with the before mentioned process can withstand a
temperature of from 65 to 85 degrees Celsius in the water bath without its
albuminous matter becoming coagulated. Thus when the lupinus has not been
treated in accordance with this invention and is placed in a water bath of below
65 degrees Celsius the albumen is washed out, and in a water bath of above
477

65 degrees Celsius it is coagulated, in either case from 40 to 50 per cent of the
feeding value being lost, which does not occur when these improvements are
employed, which are substantially for the purpose of extracting the bitter ingredient
of the lupinus plant by means of drying the said lupinus by heat without allowing
the temperature of the same to exceed 70 degrees Celsius whereupon the albuminous
matter contained therein reaches a state which allows of it being subjected to a
water bath of from 65 to 85 degrees Celsius, without passing over into an insoluble
state, the bitter ingredient being finally extracted in a water bath of a temperature
of from 65 to 85 degrees Celsius.

89 Chancery Lane in the County of Middlesex do hereby declare the nature of
said invention for "IMPROVEMENTS IN THE TREATMENT OF THE LUPINUS PLANT
(LUPINE) TO ADAPT IT FOR USE AS FOOD FOR CATTLE, a communication to me
from abroad by R. Habermann of Berlin in the German Empire, Engineer, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
The object of this invention is to extract from the lupinus plant, the bitter
ingredient which renders it unsuitable for use as food for cattle, without at the
same time, impairing its nourishing properties.
The lupinus plants are first kiln dried or otherwise dried at a temperature not
exceeding 70 degrees Celsius. Then for the purpose of expelling the bitter
ingredient they are placed in a water bath of a temperature of between 65 and
eighty five degrees Celsius, in which they may be agitated if found necessary. By
the drying process the small albuminous bodies or particles contained in the plants
are caused to pass over into a state which preserves them from coagulation when
treated in the water bath. If the latter is of a temperature below 65 degrees
Celsius a considerable portion of the albumen is dissolved and lost for feeding
purposes; if higher than 85 degrees Celsius à considerable portion of the albumen
passes over into an insoluble state and is thus rendered unsuitable.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
The process for extracting the bitter ingredient from the lupinus plant without
impairing its nourishing properties, the said process consisting in first drying the
plant in a kiln or by other suitable.means, and then subjecting the same to a water
bath, substantially as hereinabove described.
