Abstract

Gastropods are the largest class of the phylum mollusks, with 75,000 identified species. Gastropods are widely distributed in freshwater, marine waters, and mangrove ecosystems. Gastropods are a fishery commodity with an important economic value containing high protein (36-70.8%) and low fat (0.02-1.50%). This biota has vitamins, essential minerals, omega-3, and omega-6. This research aimed to determine the proximate content (protein, fat, water, ash, and carbohydrates) and macrominerals (Na, K, Mg, Ca, and P) in gastropods found in Bakau Village, Sambas Regency, West Kalimantan. The gastropods found were Ellobium, Cerithidea, and Pirenella. Fifty individuals were taken for proximate analysis. Moisture and ash content were determined by the gravimetric method. Total protein levels were analyzed by the Kjedahl method. The fat content was determined by the Soxhlet method, and the carbohydrate content by the by difference method. Atomic Absorption Spectrophotometer determined mineral macro. The proximate content of mangrove gastropods in Bakau Village is high in protein (48.06–54.62%) and low in fat (1.31–7.40%). The most elevated protein was 54.62 in Ellobium and Pirenella, with the lowest fat being 1.31%. The macro mineral content in gastropods is Ca (14.91-91.48 mg/kg), Mg (13.16-21.74 mg/kg), Na (8.19-20.62 mg/kg), K (13.07-17.33 mg/kg), and P (0.66-0.71 mg/kg). The highest mineral content was shown by the genus Pirenella (91.48 mg/kg) Ca. Keywords: gastropod, macromineral, mangrove, proximate.

Desa Bakau Sambas 地区红树林中腹足类动物的近似物和宏矿物质含量
腹足纲动物是软体动物门中最大的一类,目前已确认有 75,000 个物种。腹足类广泛分布于淡水、海水和红树林生态系统中。腹足类是一种具有重要经济价值的渔业商品,含有高蛋白(36-70.8%)和低脂肪(0.02-1.50%)。该生物群含有维生素、必需矿物质、欧米茄-3 和欧米茄-6。这项研究旨在确定在西加里曼丹省三巴斯县巴考村发现的腹足类动物的近似含量(蛋白质、脂肪、水分、灰分和碳水化合物)和大矿物质(钠、钾、镁、钙和磷)。发现的腹足类动物有Ellobium、Cerithidea和Pirenella。采集了 50 只进行近似分析。水分和灰分含量采用重量法测定。总蛋白质含量用 Kjedahl 法分析。脂肪含量用索氏法测定,碳水化合物含量用差分法测定。原子吸收分光光度计测定宏观矿物质含量。巴考村红树林腹足类的近似含量为高蛋白(48.06-54.62%)和低脂肪(1.31-7.40%)。蛋白质含量最高的是Ellobium和Pirenella,为54.62%,脂肪含量最低,为1.31%。腹足动物的宏观矿物质含量为 Ca(14.91-91.48 毫克/千克)、Mg(13.16-21.74 毫克/千克)、Na(8.19-20.62 毫克/千克)、K(13.07-17.33 毫克/千克)和 P(0.66-0.71 毫克/千克)。关键词:腹足类;大矿物质;红树林;近似物 摘要腹足类是软体动物门中最大的一类,已确认的种类有 75,000 种。腹足类广泛分布于淡水、海水和红树林生态系统中。 腹足类是具有重要经济价值的渔业商品之一,含有高蛋白(36-70.8%)和低脂肪(0.02-1.50%)。这种生物群还含有维生素、必需矿物质、欧米茄-3 和欧米茄-6。本研究旨在确定在西加里曼丹省三巴斯县巴考村发现的腹足类动物的近似含量(蛋白质、脂肪、水分、灰分和碳水化合物)和大矿物质(钠、钾、镁、钙和磷)。这项研究中发现的腹足类动物有Ellobium、Cerithidea和Pirenella。每种腹足类动物都采集了多达 50 个个体进行分析。水分和灰分含量用重量法测定。总蛋白质含量用 Kjedahl 法分析。脂肪含量用索氏法测定,碳水化合物含量用差值法测定。宏观矿物质用原子吸收分光光度计测定。巴考村红树林腹足类的近似含量为高蛋白(48.06-54.62%)、低脂肪(1.31-7.40%)。蛋白质含量最高的是Ellobium和Pirenella,为54.62%,脂肪含量最低,为1.31%。腹足动物的宏观矿物质含量为 Ca(14.91-91.48 毫克/千克)、Mg(13.16-21.74 毫克/千克)、Na(8.19-20.62 毫克/千克)、K(13.07-17.33 毫克/千克)和 P(0.66-0.71 毫克/千克)。矿物质含量最高的是海胆属(91.48 毫克/千克)。 关键词:腹足类;大矿物质;红树林;近似物。
