Abstract

The proximate composition of Padina boergesenii (Allender & Kraft) a brown alga from Vadakkadu coastal regions; Southeast coast of India was analyzed. Dry matter, crude protein, ether extract (lipids), carbohydrates, ash and total dietary fiber content of three samples were determined by standard methods. P. boergesenii showed a high content of ashes (45.65%), carbohydrates (44.05%) and total dietary fiber (47- 56% on dry basis). About 8.69% of protein, 1.23% of lipids was low. The species showed temporal variations in the percentages of proteins, lipids, minerals, dietary fiber contents, and non-nitrogenous extracts. Padina boergesenii presented comparable values to those of algae used actually as food in the region.
