Quoting the experiments for some time
The method is fully outlined in tht
latest report to the board of health
which is. in part, as follows:
IN view OF the great economic inn
portance of the pineapple industry tC
this territory, and further considering
the fact that the annual production
is now more than 100000 cases
which, according to present methods
OF canning, represents only about AZ
per cent OF the fruit, we have deemed
il advisable to carry out any expert
ments which might have a bearing on
the possible utilization of the present
enormous waste, totaiing 60 per cent
We would also mention that DR..
AIsberg, chief of the bureau of chem
istry, has given his hearty personal
Endorsement to any work this office
might do in connection with this sub
ject.
During May we conducted a pre-
liminary experiment based en- the prin-
cipfe OF freezing the pineapple juice
extracted from the waste refuse, crush
ing the ice and centrifuging the same,
the idea being to remove a consid-
cradle amount of water, leaving the
solids and all of the fruit principle as
a syrup.
Theory Was Correct.
The experiment showed that our
theory was correct, as the original
juice contained about IL per cent Of
solids, while the juice extracted from
the crushed ice by the centrifugal
method contains about % per cent Of
solids, as well as all the fruity flavor
OF the original juice. Without doubt
it would be possible to secure a juice
having more than q per cent Of solids,
and possibly 40 per cent, if that were.
deemed advisable.
At the present time we need not
go into greater detail than to say that
cur brief preliminary experiment has
shown that II would be possible to
make, through the freezing and CEN
trifugal process, beverage containing
practically all the fruity principle of
the pineapple, or a syrup having much
CT the fruit acid removed, to be used
to replace wholly or In part the ex.s
pensiye sugar solution at the present
time used In canning.
Plant Cost Prohibitlve?
THE point of greatest importance
to be considered here, however, is
that while we are convinced that it
is experimentally possible to make, as
Aforesaid. either a pleasant beverage
or a concentrated syrup for canning,
yet the great economic question arises
as to whether or not the cost of the
freezing plant would render the meth
cd prohibitive.
"Our present plan is to carry out
another experiment on a slightly larg-
er scale so as to secure little more
Of the concentrated juice prepared as
a beverage and that prepared as q
canning syrup, and then take the mat
ter up more definitely with any pine
apple men who may be interested .
Has Many Advantages.
Speaking of the experiments, Mr..
Hansen said today:
The advantages to be derived from
concentrating pineapple juice by the
simple device of throwing out much
of the water as ice, are numerous.
such a concentrated juice would
naturally be shipped more cheaply
than the original bulky product. Ar
riving at its destination in the cities
OF the mainland it could be changed
back to the original juice. if desired,
by the simple device of adding water.
THE concentrated juice, by reason
OF the high sugar content, has excel
lent keeping qualities. Further, it is
evident that, by the freezing process.
the naturally fine flavor is entirely
conserved.
