Types of Seaweed

Seaweed encompasses a wide range of species, each with its own unique characteristics and applications. The three main types of seaweed are red algae (Rhodophyta), brown algae (Phaeophyta), and green algae (Chlorophyta). Each type differs in terms of color, structure, and the pigments they contain.
Red algae: Red algae are primarily found in warm tropical waters, although they can also thrive in colder regions. They are known for their rich content of carrageenan, a substance commonly used as a thickening agent in the food industry.
Brown algae: Brown algae are the largest and most structurally complex type of seaweed. They are commonly found in cool temperate waters and are known for their high concentration of iodine. Brown algae, such as kelp, have been widely used in traditional Asian cuisine.
Green algae: Green algae are often found in freshwater and marine environments. They contain a high level of chlorophyll, which gives them their distinctive green color. Green seaweeds are commonly used in sushi and salads due to their mild flavor.
