Analysis of the Nile Tilapia fish's (Oreochromis niloticus L.) proximate composition in Sakon Nakhon province, Thailand

Fish is a significant source of animal protein and contains additional vital nutrients for people. Fish popularly eaten in Thailand is the Nile Tilapia fish (Oreochromis niloticus L.), which is inexpensive. Therefore, this study aimed to ascertain and compare the proximate compositions of the sun−dried Nile Tilapia fish from the Suanpa Baandin farm in Chiang Khruea sub−district, Mueang Sakon Nakhon district, Sakon Nakhon province, Thailand. The parameters of proximate compositions consisting of moisture contents, crude proteins, crude fats, crude ashes, crude fibers, carbohydrate contents, and total carbohydrate contents were evaluated following the standard method from the official methods of the Association of Official Analytical Chemists International (AOAC; 2004). In this investigation, the dry matters of Nile tilapia fish were 19.43 ± 0.03%. According to the findings, the sample of sun-dried Nile Tilapia fish comprised 14.2725 ± 0.0601% of crude proteins, 2.4438 ± 0.0134% of crude fat, and 1.6933 ± 0.0460% of total carbohydrate contents, respectively. These results of the sun−dried Nile Tilapia fish showed that proximate nutritional compositions were consistent with the findings of other research reports. Therefore, the overall results indicated that the sun−dried Nile Tilapia fish samples were suitable for human protein requirements and should be recommended for consumption as it was a good source of nutrients.
