Fish is considered an important food because it includes main nutrients (proteins, fats, and ash) and micronutrients (vitamins and minerals). The assessment of fish nutritional content data may offer crucial recommendations regarding freshwater fish consumption and preserving human well-being.
Evaluate the safety and quality properties of Nasser Lake fish, Aswan, Egypt.
A total of 250 samples, 50 of each Nile tilapia, Nile perch, Zander, Catfish, and Elephant-snout, from Nasser Lake, Aswan, Egypt; beheaded, eviscerated, filleted, and minced for determination of proximate analysis, amino acid, fatty acids (FAs), minerals and heavy metal, histamine content, cholesterol content, and sensory assessment.
The proximate analysis showed that all the samples examined were of good protein sources, with mean values ranging from 15.92% to 22.89%. Nile perch exhibits the highest levels of total FAs and amino acids. Heavy metal concentrations varied considerably among the analyzed samples, with a significant variance in the detection of metals among the examined fish. The findings show low histamine and cholesterol levels in the examined species, and were in accordance with those set by the National Food Safety Authority (NFSA) and the European Union Commission (EC). Accordingly, all samples are accepted based on their sensory properties.
Nasser Lake fish are of high nutritional value and have an excellent supply of amino and FAs.
鱼类被认为是一种重要的食物，因为它包含主要营养素（蛋白质、脂肪和灰分）和微量营养素（维生素和矿物质）。评估鱼类营养成分数据可以为淡水鱼的消费和维护人类健康提供重要建议。
评估埃及阿斯旺纳赛尔湖鱼类的安全性和质量特性。
从埃及阿斯旺的纳赛尔湖采集了 250 个样本，每个样本包括 50 个尼罗罗非鱼、尼罗河鲈鱼、梭鱼、鲶鱼和非洲肺鱼，进行了常规分析、氨基酸、脂肪酸（FA）、矿物质和重金属、组氨酸含量、胆固醇含量和感官评估。
常规分析表明，所有检查的样本都是优质蛋白质来源，平均值在 15.92%至 22.89%之间。尼罗河鲈鱼表现出最高水平的总 FA 和氨基酸。分析样本中的重金属浓度差异很大，检测到的金属在检查的鱼类之间存在显著差异。研究结果表明，检查的物种中组胺和胆固醇含量较低，符合国家食品安全局（NFSA）和欧盟委员会（EC）的规定。因此，根据感官特性，所有样本均被接受。
纳赛尔湖鱼类具有很高的营养价值，并且含有丰富的氨基酸和 FA。
