Mud crab () is one of the most important crustacean species in Bangladesh due to its high economic value. Crab fattening is widely practiced in the country to meet export demand while the supply for domestic consumption is mainly dependent on wild sources. This work reported for the first time a comparative evaluation of the nutritional properties of wild and fattening mud crabs. For this purpose, the proximate compositions were determined in terms of total contents of protein, moisture, ash, lipid, and minerals. Female fattening mud crabs had the highest levels of protein (17.07 ± 1.52%) and moisture (76.95 ± 1.39%) content, while the highest percentages of ash (4.9 ± 1.03%) were detected in male fattening mud crabs. Male fattening mud crabs also contained high amounts of minerals, especially calcium (1199.71 ± 343.43 mg/100g) and iron (14.21 ± 1.28 mg/100g). Male and female wild crabs showed the highest levels of magnesium and phosphorus, respectively. Additionally, the calculated percentage of recommended nutrient intake (RNI) value revealed that mud crab contributes 4.4-59.99%, 6.6-53.98%, and 7.33-54.53% for infants, adults, pregnant and lactating women, respectively. The present study indicates that mud crab had a balanced nutritional composition that would be nutrient-rich excellent diet for consumers.
青蟹()因其较高的经济价值,是孟加拉国最重要的甲壳类物种之一。该国广泛开展蟹类育肥以满足出口需求,而国内消费供应主要依赖野生资源。这项工作首次报告了对野生和育肥青蟹营养特性的比较评估。为此,根据蛋白质、水分、灰分、脂质和矿物质的总含量测定了近似成分。雌性育肥青蟹的蛋白质含量(17.07 ± 1.52%)和水分含量(76.95 ± 1.39%)最高,而雄性育肥青蟹的灰分百分比最高(4.9 ± 1.03%)。雄性育肥青蟹还含有大量矿物质,尤其是钙(1199.71 ± 343.43毫克/100克)和铁(14.21 ± 1.28毫克/100克)。雄性和雌性野生蟹分别显示出最高水平的镁和磷。此外,计算得出的推荐营养素摄入量(RNI)值百分比表明,青蟹分别为婴儿、成年人、孕妇和哺乳期妇女贡献了4.4 - 59.99%、6.6 - 53.98%和7.33 - 54.53%。本研究表明,青蟹具有均衡的营养成分,对消费者来说将是营养丰富的优质饮食。
