Description:
The effects of groundnut oil and sodium chloride as protectants against insect infestation of dried fish were investigated for a period of 13 weeks. The fish samples were divided into 3 groups, a group was soaked for 10mins in 30% sodium chloride solution (Brine), and the second group was dipped in groundnut oil after smoking while the third group served as control. The samples were kept in different containers in the laboratory at temperature of 28oC and 70% Relative humidity for 13 weeks. Results show that, the fish treated with 30% sodium chloride was effectively protected from insect and moulds compared to sample treated with groundnut oil. The odour and the texture were also more attractive to customers. However, fish treated with groundnut oil was attacked by insects at week 12th and 13th with 6 Maculatus, 4 Necrobia rufipes species and at few mould colonies. The control specimens however was attacked by insects from week 8th to 13th with numerous number of both Necrobia rufipes and Maculatus species as well as mould colonies showing as early as from the 6th week. The results proved that sodium chloride is more effective than groundnut oil for long period of storage.
