Taste activity value, free amino acid content and proximate composition of Mountain trout (Salmo trutta macrostigma Dumeril, 1858) muscles
Authors
Abstract:
In the present study, we identified free amino acid (FAA) contents and chemical composition in four populations of Salmo trutta macrostigma living in Mediterranean region of Turkey. In addition, taste impacts of FAAs were evaluated by taste active values. Moisture, protein, fat and ash content were found in the ranges of 75.49 - 79.59 %, 16.94 - 19.97 %, 1.58 - 3.75 % and, 1.39 - 1.56 %, respectively. While the significant difference (p < .05) were found among the different populations in moisture, protein and lipid content, no significant (p>.05) differences in ash content was determined. Thirteen FAAs were identified from the muscle tissue of S. trutta macrostigma by HPLC. The Glycine was found predominant as followed by methionine, proline, and glutamic acid. Also, the amount of non-essential free amino acids in S. trutta macrostigma muscle were significantly (p < .05) higher than the essential amino acids. Glutamic acid, methionin, glycine, aspartic acid and lysine were of high taste activity values (greater than one), they had strong taste impacts on the mountain trout meat flavour.

Immunohistochemical study of the endocrine cells in the stomach and pyloric caeca of the mountain trout, Salmo trutta macrostigma
The endocrine cells of Salmo trutta macrostigma stomach and pyloric caeca have been investigated using immunohistochemical techniques. 8 antisera were tested and 6 of them were detected in the endocrine cells serotonin, somatostatin, substance P, galanin, CCK and neuropeptide Y. These immunoreactive cells are described for the first time in the stomach and pyloric caeaca of Salmo trutta macros...

Morphological differences in the skin of marble trout Salmo marmoratus and of brown trout Salmo trutta.
Despite being genetically very closely related, the marble trout Salmo marmoratus and the brown trout Salmo trutta exhibit marked phenotypic differences, particularly with regard to skin pigmentation. Histological analysis of skin from the head and gill cover of differently aged individuals of the two species was carried out in order to characterize differences in skin structure. The basic stru...

The main objective of the current study was to analyze the proximate composition and the amino acid profile of the Persian sturgeon (Acipenser persicus). Forty-eight fish (with an initial weight of 96.60 7.45 g) were randomly sampled from a local sturgeon farm in Mazandaran, Iran. The proximate analysis of the fish body showed 24.38 ± 1.62 g/100g ww of dry matter, 61.52 ± 1.65 g/100g dw of cr...
