Ulvan is a sulfated cell-wall polysaccharide of the green algae, Ulva sp. It is mainly made up of l-rhamnose, d-xylose, d-glucose, d-glucuronic acid [11] and small amounts of sulfate groups positioned in xylose and rhamnose units [84–86].

To date ulvan is the less studied and investigated seaweed polysaccharide. Ulvan’s rheological properties are attractive and because of this, ulvan is considered as a food-grade polysaccharide [29]. It has a unique gel-forming mechanism, quiet complex and not yet understand, which make ulvan viscous than Arabic gum. Ulvan polymers and oligomers have comprehensive biological and pharmacological activities, such as antioxidant, antihyperlipidemic, proliferation, adhesion, anti-tumoral and anti-influenza [11, 30, 85–86]. In formation of biodegradable films, ulvan has an application area, for minimizing the microbial population.
