Seaweeds are one of the attractive organisms found in oceans with great ecological importance and contribution in increasing the biodiversity of ecosystems where they are originated and inhabited. Seaweeds have been used as human food since ancient times. The use of seaweeds as a food traced back to the 4th century in Japan and 6th century in China. Especially, those people who lived near to the coastal area preferred to consume seaweeds as a main or side dish, or either as a soup. In addition to the nutritious value, seaweeds are rich source of structurally diverse bioactive components such as phlorotannins, sulfated polysaccharides, and pigments. Moreover, some studies have reported that bioactive metabolites isolated from marine origins are safer than the land plants for drug discovery and apply for other potential industries such as cosmeceuticals and functional foods. Other than the safety, ability to mass produce with less cost of production is another advantage of seaweed origin bioactive compounds. Accordingly, bioactive metabolites isolated from seaweeds have potential to apply as an ingredient in the industries including functional foods, pharmaceuticals, and medicals.
However, Sri Lankans consume a neglectable amount of seaweeds compared to the other Asian countries due to their food habits. Besides that, industries in Sri Lanka also barely use seaweed metabolites as active ingredients in value-added products even though seaweed-based functional products owe huge demand in the international market. One reason for the less seaweed consumption and utilization in the functional industries is the lack of scientifically proven knowledge about health benefits associated with seaweeds. Therefore, my current and future research focuses on identifying and characterizing bioactive properties of seaweed species in Sri Lanka to utilize them in industries such as functional foods and cosmeceuticals.
