The carob tree flowers in September and
October. The flowers on female carob trees must be pollinated by pollen from
the male trees. Developing carob pods have the appearance of green broad
beans but they turn a dark glossy brown with maturity. They are between 4"
and 10" long and weigh 0.75 to 1.5 oz.. The pods contain four series of oval
holes, each bearing a seed like a watermelon seed. Each pod can contain up
to 15 seeds. Carob bean, seeds and pods are edible. The ground seeds are
used as a substitute for cocoa and as a food (also known as algarroba,
St. John's bread, and locust bean gum). The pods are commonly used as cattle
feed. Carob powder is also used as a food stabilizer and as a darkening
agent.Harvesting & Processing Whole Carob
Pods
Carob pods are usually processed in their
country of origin. They are both dry and wet cleaned and kibbled (coarsely
ground) to separate the seeds from the pulp. The seeds are then processed to
produce locust bean gum (ceratonia or carob bean gum). This is a natural
product used as a gelling agent, stabilizer or emulsifier in ice cream,
dessert fruit filling and salads.
The gum may be mixed with tragacanth gums
(E143) which exude from the trunk and branches of another species of the pea
family. This is also used as a stabilizer, emulsifier, thickener, or to
prevent sugar crystallization in confectionery. An oil called algaroba is
extracted from the carob seeds to be used for medicinal purposes. After
seed extraction, the pods are roasted, milled and sieved and then stored in
controlled conditions to prevent them becoming hard and lumpy. Carob powder
is used in baking and food manufacture. It is naturally sweet so no added
sugar varieties are available. Non-dairy carob bars use vegetable fat, soya
flour and soya lecithin as an emulsifier.
History of Carob Bean
Pods
Although it has only been used in manufacture and
baking in Britain for some 20 years, carob is by no means a newly discovered
food. The Greek Theophratus recorded in 4BC that his contemporaries called
the carob the Egyptian fig. Ancient Egyptians used the gummy properties of
carob seed by using it as an adhesive in binding mummies and the pods and
seeds have been found in Egyptian tombs. The Romans are said to have eaten
the pods when green and fresh for their natural sweetness.
Many scholars believe that John the Baptist
lived on carob pods as" the locust bean" in another name for carob bean
pods. Another biblical reference to carob pods is also probable in the
parable of the prodigal son who squandered his inheritance and so became a
servant, looking after the pigs. "He would gladly have fed on the pods that
the swine ate ..."- the pods would most probably have been the pods of the
carob trees which would still produce crops in times of drought and famine.
Alternative to Chocolate
Carob beans have rightly been coined the healthy
alternative to chocolate. As most of us are now aware, carob is free from
the stimulants caffeine and theobromine found in chocolate. It is also
naturally sweet, so carob products will generally contain substantially less
sugar than their chocolate counterparts. Carob powder can be substituted
for cocoa powder in any recipe. Carob is also available in bars, drops and
in confectionery.
Advantages of Carob Over
Chocolate
Carob pods is free from caffeine and theobromine
which can be addictive and can cause allergies. Caffeine and theobromine are
stimulants. Caffeine is the most active and works directly on the brain
stimulating the senses, inspiration and alertness. It can be transmitted
through breast milk and pregnant women are advised to restrict their
caffeine intake. Caffeine has analgesic properties but also has side-effects
such as anxiety, nervousness, nausea, and palpitations. Caffeine not only
stimulates the brain and other organs but also increases the heart rate. It
can provoke emotional reactions. It stimulates the gastric juices and acts
as a diuretic and so can cause excess loss of the water soluble vitamins B &
C. Caffeine stimulates release of the body's stored energy reserves, meaning
that sugars are released into the blood. This can increase the risk of
diabetes and possibly obesity and can cause mood swings.
How Much
to Eat?
Commonly, 15 grams of carob powder is mixed with applesauce for children.
Adults can take at least 20 grams a day. The powder can be mixed in
applesauce or with sweet potatoes. Whole carob pods should be taken with
plenty of water. Please note that infant diarrhea must be monitored by
a health care professional and that proper hydration with a high electrolyte
fluid is critical during acute diarrhea. Carob pods are free from
phenylethylamine which can trigger migraines and allergic reactions.
Nutritional Information
Whole carob pods are
high in protein and contains
multiple vitamins. It is also high in calcium, phosphorus,
potassium and magnesium and contains iron, manganese, barium, copper and
nickel. However, it should of course only be eaten in moderation alongside a
balanced diet. It has no oxalic acid which prevents the body using calcium
and zinc. These minerals are vital to a healthy skin and the presence of
oxalic acid in chocolate may be connected to the onset of spottiness noticed
by some teenagers on the consumption of larger amounts of chocolate.
Active constituents:
The main constituents of carob are large carbohydrates (sugars) and tannins.
The sugars make carob gummy and able to act as a thickener to absorb water
and help bind together watery stools. Tannins from carob, being water
insoluble, do not bind proteins as some tannins do. Carob tannins do bind to
(and thereby inactivate) toxins and inhibit growth of bacteria, both of
which are beneficial when it comes to diarrhea. Dietary fiber and sugars
may make food more viscous in the stomach and thus interfere with reflux of
acid into the esophagus.
