Abstract
ABSTRACT Minerals, although required in relatively small amounts, play crucial roles in many vital processes of the human body, and their deficiency can cause several serious health issues. Seaweeds and seagrasses, traditionally consumed as vegetables in coastal areas worldwide, are generally known as a rich source of macro- and microminerals in concentrations much higher than in terrestrial plants. Despite their significant nutritional potential, the mineral composition of most of the seaweeds and seagrasses remains unexplored. In the present study, the concentrations of 23 minerals in nine seaweeds and seagrasses from the Philippines were determined using inductively coupled plasma optical emission spectroscopy. The results showed that some of the species are excellent sources of various essential minerals. Actinotrichia fragilis and Mastophora rosea were the highest in calcium content (21,511 and 14,100 mg/100 g DM, respectively), and, together with Anadyomene plicata, they were richest in copper (2.49–3.77 mg/100 g DM), iron (292–480 mg/100 g DM), manganese (22.3–27.2 mg/100 g DM), and nickel (1.49–2.93 mg/100 g DM). Moreover, M. rosea had the highest content of magnesium (2,093 mg/100 g DM). Other species, such as Enhalus acoroides (phosphorus in flowers and seeds, 277 and 282 mg/100 g DM, respectively), Halophila ovalis (silicon, 13.8 mg/100 g DM), Halymenia dilatata (zinc, 5.51 mg/100 g DM), Halymenia maculata (sulphur, 8,268 mg/100 g DM) and Portieria hornemannii (potassium, 8,985 mg/100 g DM; vanadium, 2.90 mg/100 g DM) can be highlighted as good sources of minerals. All these species have a promising potential as mineral-rich foods and can contribute to food and nutrition security.
摘要:尽管所需的矿物质相对较少,但在人体的许多重要过程中发挥着至关重要的作用,而矿物质的缺乏可能会导致一些严重的健康问题。海藻和海草传统上在世界各地的沿海地区作为蔬菜食用,通常被认为是宏观和微观矿物质的丰富来源,其浓度远高于陆地植物。尽管它们具有巨大的营养潜力,但大多数海藻和海草的矿物成分仍未被探索。在本研究中,使用电感耦合等离子体发射光谱法测定了菲律宾9种海藻和海草中23种矿物质的浓度。结果表明,一些物种是各种必需矿物的良好来源。脆弱放线菌和玫瑰Mastophora rosea的钙含量最高(分别为21511和14100 mg/100 g DM),与褶皱Anadyomene一起,它们富含铜(2.49–3.77 mg/100 g DM)、铁(292–480 mg/100 g DMs)、锰(22.3–27.2 mg/100 g)和镍(1.49–2.93 mg/100 g dms)。此外,M.rosea的镁含量最高(2093mg/100g DM)。其他物种,如橡果Enhalus acoroides(花和种子中的磷,分别为277和282 mg/100 g DM)、卵嗜盐菌Halophila ovalis(硅,13.8 mg/100 g DM。所有这些物种都有潜力成为富含矿物质的食物,并有助于粮食和营养安全。
