GUM AND STABILIZERS

Gums and stabilisers are integral components in food and industrial applications, functioning primarily as thickening, gelling, or texturizing agents. These substances, comprising polysaccharides and proteins, are water-soluble and can form films, encapsulate ingredients, suspend particulates, stabilize emulsions, and control crystallization.
