  • Carob tree (Ceratonia siliqua L., Leguminosae family), which is widely cultivated in the Mediterranean area, is considered to be an important component of vegetation for economic and environmental reasons .
  • Carob pod is the fruit of the carob tree (Ceratonia siliqua L.), and is mostly used in the food industry for carob bean gum and locust bean gum, which are polysaccharides (galactomannans) contained in the endosperm of the seeds.
  • Locust bean gum is a polysacharide (a long chain made of sugars) made of the sugars galactose and mannose. 
  • Locust bean gum: is the preferred gum in frozen desserts, cultured dairy products, cream cheese and more. It is available from stock with top viscosity, several granulations and low microbiology.
  • In more recent times is is used as a thickener in salad dressings, cosmetics, sauces, as an agent in ice cream that prevents ice crystals from forming, and as a fat substitute.
  • Food manufacturers use locust bean gum, which provides high viscosity and functions as a water binder, in a wide range of processed foods like cheese, ice cream, bakery products and soups.
  • 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. 
  • A number of grades of locust bean gum are available, and for each grade it is possible to have different particle sizes according to the requirements of the end user. The main gum-producing countries are Spain, Italy and Portugal. 
  • The production of Locust Bean Gum is not a common industrial production. In fact there are only 12 LBG plants in the world, and each one has developed its own technology.
  • 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.
