Of the boiling hot syrup taken directly
from the evaporator These directions
should be followed as closely as pos
sible but slight variations will not
materially affect the result. For in
stance, the recommended density of 20
deg Baume should be taken as
standard but a deviation of 2 or 8 de-
grees either way is permissible. The
same way be said of the temperature.
The temperature of the semi-syrup
should preferably be at lao deg. F.,
when the invertase is added, but a
range of deg. higher or 10 deg. lower
may be allowed. Three pints of in
vertase to 100 gallons of semi-syr0p
has ben found to bring about sufficient
inversion of sucrose to invest sugar
TO prevent capitalization. The addi-
tion of a larger amount of invertase
than this proportion will only result in
the inversion of more sucrose than is
necessary, but this will in no way in
jure the finished syrup.
The choice OF twelve hours for the
action of the invertase on the semi
syrup is made as being a convenient
length of time. An hour or two less
time will not greatly effect the result.
A slightly longer time will only re-
suit in a somewhat greater inversion
cf the sucrose which will not be objec-
tionable. The method above outlined
can be used in both large and small
syrup plants.
The process of making cane syrup
as described above is naturally a little
more troublesome and expensive than
the present very simple methods em-
Iployed in our southern states with the
Exception of Louisiana. However, the
advantages that will result from the
manufacture of better product, one
that will not crystalline or readily
ferment, should far more than counter
balance the additional trouble and ex-
pense involved in this process. Syrup
made by this method can also be pack
ed in fiber containers with much more
satisfactory results than syrup made
by the usual methods.
Trial Demonstrations of this Method
Specially Important
| This method of preventing fermen-
tation and capitalization may be cas-
lily tried on a small scale at negli-
gible expense. For the purpose of
making a small trial run it is only
necessary to have two or three clean
barrels in which. semi-syrup may be
placed. Any other suitable container
may be used. Large mills will prob
ably already have extra tanks or
other containers which can be used. An
appropriate amount of semi-syrup of
approximately 20 deg. Baume is pre-
pared and placed in the barrels or
other containers, the temperature is
Iadjusted to as near LAO deg. Fahren-
heit as possible. the proper amount Of
invertase is added and the semi-syrup,
after through mixing, is allowed to
stand over night. The regular pro-
cess used by the syrup maker is then
interrupted for a sufficient length OF
time the next day to evaporate the
semi-syrup to finished syrup If
however, this method is adopted as a
permanent process two evaporators
must. of course, be used and two addi-
tional tanks provided as already in
ld;cated.
The bureau of chemistry will, SC
far as possible, furnish, upon request
louring the season of 1920 sufficient
Iamount of invertase free of charge tt
any syrup producer who wishes to try
this method on small scale and vii
send representative TO give demon
stration of the method. There will b
! no expense to the syrup producer fol
} this demonstration. Those who wish
. a demonstration of this method shoulC
write Immediately to the Bureau Of
) Chemistry, U. S. Department of Agri
J lculture, Washington, D. c., stating
! the approximate date when they vii
begin making syrup and the approx
mate date when they will finish. /
it appears at the end of the season
that a sufficient number Of syrul
; makers wish to use this method as /;
permanent process the bureau O.
