■鱼被认为是一种重要的食物,因为它包含主要的营养素(蛋白质,脂肪,和灰分)和微量营养素(维生素和矿物质)。对鱼类营养成分数据的评估可能会提供有关淡水鱼消费和维护人类福祉的重要建议。
■评估纳赛尔湖鱼类的安全性和质量特性,阿斯旺,埃及。
■总共250个样本,每50个尼罗罗非鱼,尼罗河鲈鱼,赞德,鲶鱼,和大象鼻子,来自纳赛尔湖,阿斯旺,埃及;斩首,内脏,圆角,并切碎用于确定近似分析,氨基酸,脂肪酸(FAs),矿物和重金属,组胺含量,胆固醇含量,和感官评估。
■近似分析表明,所检查的所有样品都具有良好的蛋白质来源,平均值从15.92%到22.89%。尼罗河鲈鱼的总FA和氨基酸含量最高。重金属浓度在分析样品中差异很大,在被检查的鱼中金属的检测存在显著差异。研究结果表明,受检物种的组胺和胆固醇水平较低,并符合国家食品安全局(NFSA)和欧盟委员会(EC)的规定。因此,所有样品都是基于它们的感官特性而接受的。
■纳赛尔湖鱼具有很高的营养价值,并且具有出色的氨基和脂肪酸供应。
UNASSIGNED: 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.
UNASSIGNED: Evaluate the safety and quality properties of Nasser Lake fish, Aswan, Egypt.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: Nasser Lake fish are of high nutritional value and have an excellent supply of amino and FAs.
