Effect of smoking, boiling and freezing on the nutritional value of three species of genus Pseudotolithus commonly consumed in Cameroon

Assessment of cooking methods and freezing on the nutritional value and health risks of heavy metals in four fish species consumed in Douala, Cameroon

“…The fish samples ( Fig. 1 (a): Cyprinus carpio , (b): Arius parkii , (c): Ethmalosa fimbriata and (d): Polydactilus quadrifilis ) were put in icebox containing ice with a fish/ice ratio of 1:2, (w/w) and transported to the Laboratory [ 22 ] . The average weight and length of the fish used in this study were 513.45 ± 76.02 g and 32.61 ± 5.27 cm; 753 ± 64.29 g and 38.15 ± 4.73 cm; 312.53 ± 21.03 g and 21.10 ± 5.09 cm; 1125 ± 165.44 g and 56.1 ± 7.25 cm for Cyprinus carpio, Arius parkii, Ethmalosa fimbriata and Polydactilus quadrifilis respectively.…”

“…Smoking, boiling and freezing are the processing techniques evaluated in this study. These processing methods and preservation techniques, although intended to extend shelf life and improve the organoleptic quality of fish, are likely to affect the nutritional qualities of fish [ 22 ] . A number of studies have focused on fish cooking and preservation methods in Cameroon [ 1 , [22] , [23] , [24] , [25] ] .…”

A number of studies have focused on fish cooking and preservation methods in Cameroon [ 1 , [22] , [23] , [24] , [25] ] . However, very few studies have explored the effect of its cooking methods and the health risks associated with heavy metals.…”

Physicochemical Characteristics and Nutritional and Biological Properties of Fish Oils in Cameroon: An Overview

“…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]. In 2022, two studies were available: Noutsa et al researched the chemical characteristics, fatty acid profle, and antibacterial activity of oil from Fontitrygon margarita collected in Youpwe [21]; and Tenyang et al conducted research on the chemical characteristics of oil from Polypterus bichir bichir collected at the Maga fsh market in July Te other places of sampling were the Maga fsh market for four studies and Batié for two studies.…”

Characterization of Smoking Activity and Perception of Smoked Fish by Households in the City of Douala (Cameroon)

“…It provides a healthy source of energy, high quality proteins, vitamins (D, A, E and B12), essential minerals and particularly n-3 longchain polyunsaturated fatty acids (LC PUFA). These PUFA are mainly eicosapentanoic acid (20:5 n-3 EPA) and docosahexanoic acid (22:6 n-3 DHA), whose pleiotropic effects on health promotion and disease prevention are well recognized [1][2][3]. They also play an important role in the prevention and treatment of some non-communicable diseases.…”
