The study was designed to investigate the effect of duration of frozen storage on the chemical, microbiological and sensory profile of Tilapia fish (Sarotherodun galiaenus) collected from a research pond of the Agricultural Development Project, Akure, Nigeria, subjected to sixty days of frozen storage and analyzed at intervals of ten days. Protein content (%) ranges from 43.70 +/- 1.17-60.65 +/...

Gutting handling was applied to fresh horse mackerel (Trachurus trachurus) to study its effect on rancidity development during the frozen storage (up to 12 months at 20oC). For it, chemical (free fatty acids, FFA; peroxide value, PV; thiobarbituric acid index, TBA-i; fluorescence ratio, FR) and sensory (odour and taste) analyses were carried out. Results showed that gutting treatment of horse m...

Amino acid, Fatty acid, Meat, Freezing. Due to the effect of cold treatment on the amino acid profile of meat has not sufficiently studied. This study aimed to study the effect of freezing temperature and duration of frozen storage on amino acid profile and fatty acid pattern in imported beef meat, local beef meat, chicken breast and Nile tilapia fish. The effect of freezing on lipid and protei...

The effect of aqueous solution of citric acid (CA) on the lipid stability of the European catfish (Silurus glanis) fillets during frozen storage (up to 6 months) was investigated. Rancidity development was measured by several biochemical indices (free fatty acids, peroxides and TBA) and complemented by the measurement of expressible moisture and sensory evaluation (flesh odor, consistency and f...

  The effect of gamma radiation (1, 3 and 5 kGy) on microbial quality of farmed rainbow trout (Oncorhynchus mykiss) fillets which were stored under frozen conditions (-20° C) was studied by measuring microbiological changes in 5 months. Gamma irradiation and increasing of frozen storage time had significant effects (P<0.05) on the reduction of microorganism's population. The total count showed ...
