Red Luga (Gigartina skottsbergii)

The Red Luga (Gigartina skottsbergii) is a macroalga endemic to the cold waters of the South Pacific, particularly abundant along the southern coast of Chile. This seaweed belongs to the Rhodophyta group and has become one of the most valuable species for industry due to its capacity to produce kappa type carrageenan, a polysaccharide widely used as a thickener, stabilizer, and natural gelling agent.

At Seaweed Patagonia, we sustainably harvest Chilean red luga in collaboration with local communities, respecting the natural growth cycles and preserving marine biodiversity. Each batch is carefully selected and dried to retain its functional properties, ensuring homogeneous quality for industrial processing.

The Gigartina skottsbergii is highly valued for its carrageenan content as well as its concentration of minerals like calcium, potassium, iron, and iodine. This seaweed is widely used in food production (ice creams, dairy products, desserts), cosmetic products (gels, creams), and in the pharmaceutical industry as a formulation agent. It is also gaining ground in biotechnological and nutraceutical applications.

We offer red luga in bulk in various presentations: whole, cut, ground, or in powder form according to client needs. Our processes comply with international quality standards, traceability, and microbiological control, enabling safe exports to Europe, Asia, and North America.
