“…This could be explained by a low hydrolytic activity [24]. Peroxide number measures (amount of primary oxidation products in an oil) was lower than previously obtained by Manz and al on Ilisha africana (8.43 ± 0.11) [3]. The higher is peroxide number, the more oxidized is the fat.…”

“…It is more needed because of its richness in proteins, minerals, vitamins and lipids containing PUFA particulary omega 3 fatty acids. Omega 3 are involved in healing of inflammatory deseases [2], hyperlipidemy [3], neurological diseases [4], and liver deseases [5]. Omega 3 fatty acids areal so involved in the prevention and treatment of cardiovascular deseases [6], diabetes [7] but can also act against free radical [8] and adipomégalie [9].…”

Background: Fish is an important source of food for people. According to the FAO, It is man's most important single source of high-quality protein and dietary omega-three fatty acids. Objective: The study consisted of the chemical characterization of the oil extracted from Ilisha africana and Sardinella maderensis being fish species from the Cameroonian coast. Material and methods: The fish were collected at the fishing port of Douala, transported to the laboratory, washed with distilled water and filleted. Oil was extracted from the fillets using dichloromethane and methanol. The different indexes of the oil were determined using standard methods and the fatty acid profile by gas chromatography/mass spectrometry. Results: Ilisha africana and Sardinella maderensis are oily fish. The oil was of good quality various amounts of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA). Palmitic acid was the major SFA with 28.56% and 30.54% for Ilisha africana and Sardinella maderensis respectively. Palmitoleic acid and 15octadenoic were the major MUFAs in Ilisha africana and Sardinella maderensis, respectively. Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) the main omega 3 PUFAs. In both species DHA was the predominant fatty acid among PUFAs. Arachidonic acid and linoleic acid were the major omega 6 PUFAs in Ilisha africana and Sardinella maderensis. Conclusion: These results show that Ilisha africana and Sardinella maderensis are a good source of EPA and DHA and the nutritional quality of lipids may beneficit for human health.

“…In 2019, only one study was available, which was conducted by Tenyang et al on the chemical characteristics and fatty acid profle of oil from C. carpio from Youpwe. In 2020 [33], a total of fve studies were published: Manz Koule et al conducted research on the chemical characteristics and antihyperlipidemic potential of oil from Ilisha africana collected at the Douala fshing port [28]; Nchoutpouen et al [29] researched the hypolipemiant efect of oil from Ethmalosa fmbriata collected at the Douala fshing port; Simo et al [30] studied the chemical characteristics and antibacterial activity of oil from Lutjanus dentatus from Youpwe; and Tenyang et al conducted two studies on the chemical characteristics and fatty acid profle of oil from L. falcipinnis and O. niloticus collected at the Maga fsh market [31,32]. In 2021, four studies were conducted: Dama et al researched the composition of P. elongatus, P. senegalensis, and P. typus from Youpwe [23]; Christophe Manzkoule et al studied the chemical characteristics of oils from I. africana and Sardinella maderensis from the Douala fshing port [24]; and Ndômbôl et al conducted two studies on the chemical characteristics of oils from fsh by-products collected at Douala markets [25,26]; Njiké Ngamga et al studied the antibacterial activity of oil from of Chrysichthys nigrodigitatus [27].…”

“…Regarding the studies conducted in Cameroon (Table 3), Tenyang et al found that the flet of Arius maculatus had an oil content of 23.02% DM (dry matter) when extracted with the Bligh and Dyer method [40,44,45]. Manz Koule et al obtained an oil extraction yield by the Bligh and Dyer method of 2.55% WW (wet weight) from the flet of Arius parkii, while for the flet of Cyprinus carpio, an extraction yield of 1.78% WW was obtained by the same method [28]. Furthermore, using the same extraction method, Cristelle et al obtained an oil content of 15.32% DM and 8.05% DM, respectively, for the flet of Clarias gariepinus [37,43], while Tenyang et al showed that the flet of Clupea harengus had an oil content of 10.20% DM [36,44].…”

Due to their significant health benefits, fish oils have garnered increasing interest in recent decades. However, Cameroon’s fish oil market remains insignificant, and the few available products are imported, despite the country’s abundant marine resources. Additionally, research on Cameroonian fish oils is relatively recent and scarce. Therefore, this manuscript provides an overview of research on fish oils in Cameroon, focusing on their physicochemical characteristics, as well as their nutritional and biological properties. As of March 2023, 26 studies on fish oils in Cameroon have been published, with a focus on 23 species collected in the littoral, far-north, and west regions of Cameroon. Filets were the main parts used, and the Bligh Dyer and Soxhlet methods were the primary oil extraction techniques. Depending on the species, tissues, and extraction methods, oil contents ranged from 4.57% to 32.10% dry matter or yielded 0.36% to 66.83% wet weight. These oils generally meet recommended standards for markers of acidity and oxidation. Fatty acid profiles from 16 species showed a total of 48 fatty acids, including those that are beneficial to human health. Oils from eight species were found to significantly reduce weight, hyperlipidemia, hyperglycemia, hepatomegaly, and adipomegaly, while four species showed activity against bacteria responsible for food poisoning. Future work should include all fish species found in Cameroon, with a focus on by-products, and explore the physicochemical, functional, nutritional, and biological properties of these oils.

Smoked fish contributes to the food security of populations through its richness in nutrients and its accessibility to low-income households. This study aimed to characterize the smoking activity and the perception of smoked fish by households in the city of Douala. For this purpose, two surveys were conducted from February to May 2021. The first exhaustive, involving 35 processors identified the actors, the methods used and the most smoked fish species in three smoking centers (Youpwé, Bonassama and Manoka). The second survey, cross-sectional, of 384 households in five subdivisions of the city of Douala focused on the socioeconomic characterization of households and their appreciation of smoked fish. SPHINX software (2018) was used for descriptive data analysis. This study revealed that 85.8% of processors are over 40 years old and 97.1% have a low level of education. The smoking time varies between 8 to 48 hours and the three smoking kilns (Metal-drum, Banda and Altona) commonly used have an impact on health. However, 98% of households, regardless of their social status, consume smoked fish at least once a week, and the most consumed fish species out of more than 17 identified are bunga (27.08%), cod (22.14%), mackerel (14.58%), sole (10.16%) and pike (5.73%). The results of this study provide valuable information and constitute a working basis for improving fish smoking sector in order to guarantee the quality of the smoked fish.
