. Lack of negative influence of the drying processes on the protein of tilapia fish is of great practical importance, although drying resulted in a significant loss of ash, fibre, carbohydrate and energy value. These results show that different nutritional
components of fish undergo different changes at elevated temperatures. However, electric oven drying could improve the protein quality in tilapia fish, as compared with the conventional smoking kiln drying. The electric oven-dried samples showed higher lipids loss and slightly higher protein content than smoking kiln-dried samples This research provides basic nutritional information on freshwater tilapia fish, both raw and dried. The present study also provides a possible application of electric oven drying as an efficient drying process for fish in Oman and elsewhere.
