The Effect Of Actellic 25 Ec On Mineral Composition On Cured Fresh Water Fish: <i>Heterobranchus longifilis, Heterotis niloticus And Chrysichthys nigrodigitatus<i>

Abstract

A study to evaluate the effects of the preservative, Actellic 25 EC solution, on the mineral composition of the three freshwater fish species was carried out. Pieces of fish (samples) were analysed for mineral composition before and after traditional smoke drying and smoke drying after Actellic treatment. The investigations were carried out using fresh water fish, Heterobranchus longifilis, Heterotis niloticus and Chrysichthys nigrodigitatus. The result showed that Actellic 0.03 % solution greatly reduced the sodium content of the smoked dried fish species. Furthermore, Actellic 25 EC eroded the magnesium (Mg) content of C. nigrodigitatus and also reduced slightly the naturally high iron content of H. longifilis, H. niloticus and C. nigrodigitatus. The implications of these results are discussed.

“…The mean calcium value in this work were 0.123 ± 0.001 % in H. longifilis, 0.12 ± 0.002 % in H. niloticus and 0.121 ± 0.001 % in C. nigrodigitatus. These mean values were not significantly different at P = 0.05 and agrees with the values recorded by Nwuba (2002).…”

“…The preservative was observed to retain the zinc contents of the three fish species used in this study. Thus confirming the results of Nwuba (2002).…”

“…Besides essential amino acids and proteins, fish, also contains fats, oils, carbohydrates and fibre. Fish is also a very good source of essential vitamins and minerals (Nwuba, 1996;Nwuba, 2002;Pearson 1976;Onukuozor, 1996). Nwuba (2002) has reported minerals in freshwater fish to include, phosphorus, magnesium, sodium, potassium and iron.…”

Nwuba (2002) has reported minerals in freshwater fish to include, phosphorus, magnesium, sodium, potassium and iron. This study focuses on the extent of buildup or erosion of these mineral elements by Actellic 25 EC solution.…”
