Abstract

Highlights: Fatty acid profiles were evaluated in two Tenualosa sp. species of three locations of east cost of India. The highest DHA of 1.29 mg/100g was registered for the Tenualosa sp. species of Chilika lagoon. Indian coast Tenualosa sp. species recorded the ω -3 and omega-6 PUFA of 1.05 and 1.76 mg/100 g, respectively The level of trace metals, minerals and lipid quality index indicated Tenualosa sp. species of Indian coast are safe for human consumption and can provide numerous health benefits. Abstract: This study investigated the proximate composition and fatty acid profiles of Tenualosa sp. ( Tenualosa ilisha, Tenualosa keli ) at three leading capture points on the east coast of India i.e., Chilika, Chandravaga, and Chandipur. The Tenualosa sp. contained 89.03, 7.52, 1.66, and 1.04% of moisture, protein, fat, and ash, respectively. Out of 33 detected fatty acid components, myristic acid (C14:0) (684.67 mg/100g) was found to be the predominant saturated fatty acid (SFA) content. The ω-3 and ω-6 PUFA contents in the fish flesh ranged between 123.4 and 239.43 (avg. 177.89 mg/100g) and 293.43–543.37 (avg. 391.96 mg/100g), respectively. The highest DHA of 1.29 mg/100g was registered for the Tenualosa sp. of Chilika lagoon. The atherogenicity indices (AI), thrombogenicity indices (TI), hypocholesterolaemia / hypercholesterolemic ratio (H/h) were found to be 1.5, 0.63, and 0.62, respectively, and <2 which indicated safe for human consumption as per Food and Agriculture Organization of the United Nations (FAO-UN). The trace metal concentrations of copper (Cu), zinc (Zn), iron (Fe), chromium (Cr) were also recorded within the safe limit for consumption as suggested by the world health organisation (WHO). Hence, the Tenualosa sp. proved to be safe for consumption and can be regarded as a dietary component for good health. Graphical abstract: Image, graphical abstract
