Gökkuşağı Alabalığından elde edilen balık çorbasının besin değeri (Oncorhyncus mykiss, Walbaum, 1792)

Abstract

This study represents new information on the nutritional value of soup prepared from cultured Rainbow trout (Oncorhyncus mykiss). The proximate contents of soup were represented by 87.56% moisture, 7.22% protein, 1.59% crude fat, 0.07% carbohydrate, 1.17% dietary fibre and 2.44% ash. The energy value was calculated as 48.0 kcal/100g. Amino acid values were in the range of 183.5-1128.5mg/100g while mineral contents were varied as 0.6µg/g-19.5mg/g. The value of polyunsaturated fatty acids (PUFA) was higher than saturated fatty acids (SFA). Total PUFA and eicosapentaenoic acid + docosahexaenoic acid (EPA+DHA) were observed as 37.2 and 7.2%, respectively. These values corresponded to the values of 673.3 and 123.2 mg/100g of the edible portion of the soup within the same respect. The results of this study demonstrated that a portion of trout soup would almost cover daily recommended n-3 PUFA intake, however, higher amounts are required for the necessary levels of EPA+DHA. The vitamin B12 content was well above the recommended levels. The values of α and β tocopherols were observed as 272.0 and 1131.0 µg/100g (wwb), respectively. This study indicates that trout soup has a good nutritional value for human consumption for a healthy diet.
