General
- Locust bean gum -
also called Carob bean gum and Carubin - is extracted from the seeds
of the carob trees (Ceratonia siliqua kernels), which grow in
Mediterranean countries. Locust bean gum can act as a thickener in
cold liquids like xanthan gum. When mixed with a little bit of water
and stirred into boiling liquids, it can also form temperature-stable
gels. Locust bean gum works for a wide range of pH-values and under
otherwise critical salt/ion contents. During freezing, locust bean gum
retards ice crystal growth and gives a better mouth-feeling to frozen
products.
Preparation
-
Carob
pods were crushed mechanically in a blender and then sieved to
separate the polymer from its outer shell and from the embryo. The
polymer was washed with water and 500 mL of water was added. This
mixture was heated for 30 min to 70 C while being spinning at 500
rpm. The obtained solution was added slowly to 2 L of absolute ethanol
and mixed for 10 min at room temperature. The precipitated polymer was
filtered using a sieve (0.160 mm), separated into small pieces and
dried at room temperature. Finally, it was dried in a vacuum oven at
50 C and 2666 Pa for 8 h 10.
Applications
-
The
seeds are the source of carob gum or locust bean gum, used as an
additive by food processors in confections, frozen desserts, gelatin
salads, party dips, salad dressings, and sauces as a stabilizer and
thickening agent. It is used in baked goods to improve texture and
extend shelf life and stabilize pie fillings and meringues; in dairy
products to prevent separation of fats, solids, and water, and impart
smoothness and richness with only traces of calories; in meat products
as stabilizers and thickeners; and to give meat like texture to
vegetable protein analogs.
-
Locust
bean gum is used in a range of different food systems as a stabiliser
or thickening agent and in certain gel systems as a texture modifier.
-
The
paper industry used to be the biggest consumer of locust bean gum and
its derivatives, but its use in this field has diminished
considerably. It was added during the paper-making process to improve
the physical characteristics of the paper.
Market
- Carob has been
intermittently explored over the last 20 years as a potential tree
crop industry in areas of Australia with less than 700mm rainfall per
year. Carob pod/seed mix has considerable commercial value as a
livestock fodder supplement (A$1 40 per mt), as a thickener, in canned
products such as pet food (A$1,200 per mt) and as an ingredient in
confectionery (A$3,000 per mt).
- The world demand
for LBG requires 35,000t of carob seed per year. LBG is used in the
food industry for its strong gel characteristics, which are useful in
products such as canned pet food, since they are maintained after
heating
