Analysis and comparison of nutrients and caloric values of fillets fish fresh and processed of Carangoides ferdau

Processing of fish lead to maintain the quality and nutritional value until they are consumed. The purpose of this study was to the effects of the cooking methods of boiling, frying, and roasting on changes of amounts of nutrients (moisture, fat, protein, ash, carbohydrates), the calorie value and minerals (calcium, phosphorus, sodium, magnesium, iron and potassium) of one of the selected marine fish (Carangoides ferdau) with recommended standard AOAC methods. Results showed that the amounts of nutrients, caloric value and minerals found different variations according to fish species and processing methods. The fat, ash, carbohydrates, calories and minerals values were reduced in roasted fish, and fat, protein, ash, carbohydrates, calories and minerals values were reduced in boiled fish, while moisture, ash and minerals contents were reduced in fried fish. In general, nutrients, minerals and caloric values of the studied fish were found less changes in frying method compared with other methods.
