The chemical components and quality changes in African catfish (Clarias gariepinus) mince balls, vacuum packed and non-vacuum packed in polyethylene materials were investigated during 6 months of storage. Total volatile basic nitrogen and pH values were studied monthly, while protein, moisture, ash and lipid contents were examined at the beginning and end of storage. Sensory assessments regarding appearance, texture, succulence, odour and flavour and general acceptability were carried out at three-month intervals. All the parameters studied were above the acceptable level. The sensory scores of the products, vacuum packed and normal packed fish balls, were between 6.5 and 9.8 out of 10 and were acceptable to the panelists.
