This study identified biogenic amines, fatty acids, and volatile compounds in , an Ivorian traditionally salted and fermented fish. Samples were obtained from two processing methods (method 1: entire fish ; method 2: both sides filleted ) with the fish species . Biogenic amines found in freshly produced were histamine, putrescine, cadaverine, tyramine, β-phenyl ethylamine, and spermidine. Among these, the most prevalent were β-phenyl ethylamine and cadaverine. Biogenic amine contents varied according to the processing method but remained lower than levels considered hazardous for human health. The major fatty acids present in from method 1 were docosahexaenoic acid, palmitic acid, and oleic acid. In from method 2, the major fatty acids were oleic acid, stearic acid, and palmitic acid. The omega (w)-3/w-6 ratio was 8.87 and 4.12 for from methods 1 and 2, respectively. Most of the fatty acids are considered healthy fats, making a useful food for treating and preventing lifestyle diseases. The volatile compounds found composed of 19 aldehydes, 12 alcohols, 7 esters, 7 ketones, 3 furans, 10 aromatic compounds, and 7 acids with aldehyde, alcohol, and ester compounds as the predominant groups. Among the aldehydes, 2,4-heptadienal (E,Z), octanal, and 2-octenal (E) were most prevalent in from method 1, whereas 2-nonenal (E), 2,4-heptadienal (E,Z), and octanal were most prevalent in from method 2.
本研究鉴定了一种科特迪瓦传统腌制发酵鱼中的生物胺、脂肪酸和挥发性化合物。样本取自两种加工方法(方法1:整条鱼;方法2:双侧去骨鱼片)和该鱼类品种。新鲜制作的鱼中发现的生物胺有组胺、腐胺、尸胺、酪胺、β-苯乙胺和亚精胺。其中,最普遍的是β-苯乙胺和尸胺。生物胺含量因加工方法而异,但仍低于对人体健康有害的水平。方法1的鱼中存在的主要脂肪酸是二十二碳六烯酸、棕榈酸和油酸。方法2的鱼中,主要脂肪酸是油酸、硬脂酸和棕榈酸。方法1和方法2的鱼的ω(w)-3/ω-6比值分别为8.87和4.12。大多数脂肪酸被认为是健康脂肪,使这种鱼成为治疗和预防生活方式疾病的有益食物。发现的挥发性化合物由19种醛、12种醇、7种酯、7种酮、3种呋喃、10种芳香化合物和7种酸组成,其中醛、醇和酯化合物为主要类别。在醛类中,2,4-庚二烯醛(E,Z)、辛醛和2-辛烯醛(E)在方法1的鱼中最普遍,而2-壬烯醛(E)、2,4-庚二烯醛(E,Z)和辛醛在方法2的鱼中最普遍。
