Seaweeds or macroalgae are valuable marine plants that have garnered much attention from the public due to their high bioactive, nutrients and minerals content. They are classified into three higher taxa, namely Chlorophyta (green seaweed), Phaeophyta (brown seaweed) and Rhodophyta (red seaweed), based on their pigmentation. Due to their the valuable nutrition and bioactive components, seaweeds have been used in multiple applications, including in cosmeceutical, nutraceutical and pharmaceutical industries as well as in fine chemical and enzymes production. The extraction of these components is influenced by various process parameters such as drying methods, solvent extraction, pH, temperature, extraction time, solid to solvent ratio etc. Thus, it is important to design the experimental to get the optimised condition to get the significant amount of the interest components. Response surface methodology (RSM) is one of the economically efficient experimental procedure for optimising this complex process. Compared to using ‘one to one factor’ method, RSM is far better since in RSM the several process variables simultaneously interact with each other. Therefore, in this presentation underlying the approach of our research on the optimisation of the extraction of valuable components in seaweeds will be discussed.
