The Art Of Extracting Juices
Making juices may seem simple. There are a variety of devices
used for making juices. The ideal juicer will make the maximum
amount of liquid from a given quantity of plant material,
leaving a quite dry residue behind which, incidentally, makes a
first class material for composting organically grown fruits and
vegetables.
An electric blender can make a juice-like liquid from soft raw
materials and is quite good with raspberries and similar fruits
although it is usually advisable to add a little water to the
mixture before blending However, for nearly all sources of raw
juices the most efficient machine is a purpose built juicing
machine.
These represent a sizeable expenditure for the average family
and it is often more economical to buy one where the basic motor
unit can perform a number of different functions so that the
whole is a useful culinary aid. For example, a model which is
not only a continuous juicer but also shreds or slices for raw
salads, blends and chops.
Every type has its own special merits and its particular
disadvantages. Which you choose must depend on your individual
circumstances, but an experienced health store owner is
invariably a good and willing guide. But there are certain
points that it is as well to be aware of in advance.
Any reasonable manufacturer will give a one year guarantee
against faults in manufacture. The machine will be made of high
quality plastics and chemically inert metals, such as stainless
steel rather than the more reactive aluminum, in places where it
is in contact with the juice.
The cheapest type and one that is usually very efficient
consists of a basket with perforations into which the fresh
materials are put through the feeding hole. There are cutters
which divide the matter into fine particles. The basket whirls
round expressing the juice through the holes by centrifugal
force. After every pint or so of juice has been prepared the
machine must be dismantled (always check to see if this is a
simple or a tortuous task), the pulp has to be removed, the
machine re-assembled and the process repeated. These are
excellent value for the moderate user but very tiresome if you
want many pints each day.
The next kind is the continuous machine in which the juice comes
out of one aperture and the pulp from another. This is very
convenient and some makers claim to have juiced two tons of
apples without stopping. In these machines the design of the
pulp outlet is very critical for especially with the softer
fruits, there is a risk of clogging which if unnoticed leads to
a table covered with leaking liquids and a very messy juicer. Do
not be put off for the majority of makers have overcome such
faults. Just make certain that you buy on the understood
condition that continuous means more or less what it says.
The extraction rate is often a little lower that for other types
but this is offset by the great convenience. It is important to
remember to clean all juicing machines after use or else the
rotting and caked-on residue will make a visit to the repairers
a premature necessity.
The next class of machine is a hydraulic press which first
shreds and then subjects the pulp to between 3,000 and 7,000lb
(1375-3175kg) pressure leaving the plant matter almost bone dry.
Such a machine is costly and often hard to obtain but probably
the most efficient and certainly very desirable for
institutional use. It is too large and awkward for normal
juicing purposes.
Finally we must consider the non-electric or manual methods of
juicing which have, after all, been the only means possible
until recently Very good results are obtainable with a small
scale wine press. The fruit or vegetables are chopped and put
into a slatted, circular wooden basket a threaded post runs up
the centre and a long lever forces a strong plate downwards onto
the material forcing the juice out. A good model will last so
well that you may leave it to your heirs.
A good juicer is an investment in health that is small compared
to the great benefits you will derive from its regular use. Not
only is it essential for therapeutic purposes but, when you are
fit and well, fresh raw juices can be prepared into subtle and
delicious cocktails of entrancing gastronomic delight. Who else
but the host/hostess with a juicer can offer good health with a
drink?
