Food Quality and Characterization of Commercial Seasoned Sea Squirt Halocynthia roretzi

摘要

This study investigated the food biochemical characterization of commercial seasoned sea squirt Halocynthia roretzi (CSS). The proximate composition of CSS was 77.2-82.7% moisture, 7.1-9.1% crude protein, 0.3-2.6%) crude lipid and 3.5-6.3%) ash. Tastecompound contents of CSS were 2.3-5.4%) salinity (saltiness), 0.42-1.12 g/100 g total acidity (sourness) and 114.9-330.2 mg/100 g amino nitrogen (taste intensity). The Hunter color values of CSS were 23.79-32.50 for lightness, 9.97-20.45 for redness, 14.01-20.96 for yellowness and 64.50-76.63 for color difference. The odor intensity of CSS was 35.0-62.0. According to these results, there were large differences in proximate composition, taste compounds, Hunter color values and odor intensity of CSS. Viable cell counts ranged from 6.20 to 7.69 log (CFU/g), and most of the viable cells comprised of lactic acid-forming bacteria. CSS was not detected in the coliform group.
