LOCUST BEAN GUM: Properties and applications

Today’s approach of using natural biopolymers and bioactive materials; because they are easily available, relatively cheap and can modified by suitable reagent. Locust bean gum (LBG) is one of them that is extracted from the seeds of the Ceratoria siliqua. LBG is composed of galactomannan. It is composed of two units i.e galactose and mannose, that consist of a linear chain of(14)- linked β-D- mannopyranosyl units with(16)- linked α- D- galactopyranosyl residues. Also it has albomine, globulin and glutelin. The prepration of LBG include some steps that are:Dehusking, Splitting, Milling, Dissolution, Filtration, Alcoholic precipitation, Filtration, Drying, Milling and Packaging respectively. The functional properties of LBG are dependent on its behavior in an aqueous medium. The molecular size, mannose to galactose ratio, galactose distribution in the mannose backbone chain influences solubility and also controls the rheological properties of LBG. LBG is used as an additive in food industry due to its good thickening and stabilizing property. It is used in Edible and Coating film, Noodles, Bakery products, Low fat yoghurt, Beverages, etc. LBG also has hypolipidemic effect, decreasing LDL, protective effect on cardiovascular disease and beneficial effects for control insulin levels. It also prevents of obesity.
