Algae species have been used as an important source of food because they are highly nutritive considering their vitamin, protein, mineral, fiber, essential fatty acid and carbohydrate contents. However, a large number of seaweeds have been poorly studied, especially Brazilian species. Two red macroalgae species from the Brazilian coast (Plocamium brasiliense and Ochtodes secundiramea) were assessed with respect to their total lipid, fatty acid, total nitrogen, protein, amino acid and total carbohydrate contents.
The total lipid contents (dry weight) were 36.3 and 35.4 g kg(-1); fatty acid contents were 9.3 and 12.1 g kg(-1); total nitrogen contents were 37.4 and 24.9 g kg(-1); protein contents were 157.2 and 101.0 g kg(-1); amino acid contents were 127.5 and 91.4 g kg(-1); and total carbohydrate contents were 520.3 and 450.7 g kg(-1) for P. brasiliense and O. secundiramea, respectively.
Considering these compositions, both algae species were determined to have sources of protein, essential amino acids and carbohydrates similar to the edible seaweeds Laminaria japonica and Palmaria palmata.
藻类因其富含维生素、蛋白质、矿物质、纤维、必需脂肪酸和碳水化合物而被用作重要的食物来源。然而，大量的海藻研究不足，尤其是巴西的海藻物种。本文对巴西沿海的两种红色大型海藻（Plocamium brasiliense 和 Ochtodes secundiramea）的总脂质、脂肪酸、总氮、蛋白质、氨基酸和总碳水化合物含量进行了评估。
（干重）总脂质含量分别为 36.3 和 35.4 g kg(-1)；脂肪酸含量分别为 9.3 和 12.1 g kg(-1)；总氮含量分别为 37.4 和 24.9 g kg(-1)；蛋白质含量分别为 157.2 和 101.0 g kg(-1)；氨基酸含量分别为 127.5 和 91.4 g kg(-1)；总碳水化合物含量分别为 520.3 和 450.7 g kg(-1)。
考虑到这些成分，这两种藻类都被确定为具有类似于食用海藻裙带菜和掌状红皮藻的蛋白质、必需氨基酸和碳水化合物来源。
