Gum arabic

Gum arabic is a natural substance extracted from the dried sap of two acacia species, mainly Acacia senegal and Acacia seyal, native to the semi-arid regions of sub-Saharan Africa. It appears as translucent nodules or water-soluble powder and has been used for centuries in food as a thickening, emulsifying and stabilising agent. From a nutritional standpoint, gum arabic is largely composed of soluble dietary fibres, particularly complex polysaccharides. It contributes to nourishing the gut microbiota by acting as a prebiotic, supporting the growth of beneficial bacteria such as bifidobacteria and lactobacilli. It also contributes to a feeling of satiety and the maintenance of normal bowel transit. As a supplement, gum arabic provides an easily integrated source of soluble fibre, particularly for individuals whose daily diet is low in fibre. Its good digestive tolerability and solubility make it a versatile functional ingredient, commonly used as an excipient in food supplements.
