Gum arabic: an optimization of ultrasonic-assisted extraction of antioxidant activity

Gum Arabic (GA), also known as Acacia seyal gum (ASG), is a dried exudate from trees of Acacia senegal and Acacia seyal. It provides a rich source of non-viscous soluble fiber with significant health benefits and high antioxidant properties. Tonnes of raw GA are exported annually at a high cost with...
