Food components and sensual characterization of commercial plain-dried silver-stripe round herring

Abstract

For the effective use of under-utilized resources, silver-stripe round herring (SSRH), the plain-dried SSRH was investigated and compared with boiled-dried SSRH and boiled-dried anchovy on the food component and sensual characterization. Moisture content and salinity of the plain-dried SSRH were 31.9% and 7.6%, respectively. Moisture content of the plain-dried SSRH was higher, while the salinity was lower than those of boiled-dried SSRH and anchovy. According to the results of peroxide value, fatty acid composition, Hunter b value, and browning index, the rancidity was higher in plain-dried SSRH than in boiled-dried SSRH and anchovy. When compared to the boiled-dried SSRH and anchovy, the plain-dried SSRH was higher in calcium and phosphorus contents, while lower in total content of amino acid. According to the results of hot-water soluble-N, trichloroacetic acid-N, free amino acid, and taste value, the taste of plain-dried SSRH was superior to those of the boiled-dried SSRH and anchovy. The results of chemical components and sensory evaluation indicated that the plained-dried SSRH could be substituted for boiled-dried anchovy classified into special grade, if fish odor of SSRH can be improved.
