Locust bean gum is the ground endosperm of the seeds of the natural strains of carob tree, Cerationia siliqua (L.) Taub. (family Leguminosae). Consists mainly of a high molecular weight hydrocolloidal polysaccharide, composed of galactopyranose and mannop

Guar gum is the ground endosperm of the seeds of the natural

strains of guar plant, Cyamopsis tetragonlobus (L.) Taub. (family Leguminosae). Consists mainly of a high molecular weight hydrocolloidal polysaccharide, composed of galactopyranose and mannopyranose units combined through glycosidic linkages, which may b

We then decided to develop a new method for the reliable detection and differentiation of guar gum and LBG. This method will be based on:
• The fact that the gums are extracted from two plants of different genuses and species.
• DNA sequences which could be specific from these two plants
