Abstract

This study was carried out to investigate the quality characteristics of three types of canned conger eel Conger myriaster added seasoning sauce. The canned products of Sample-1 (Canned conger eel added Kochujang sauce), Sample-2 (Canned conger eel added Chokochujang sauce) and Sample-3 (Canned conger eel added tomato paste sauce) were made. After removing all intestines of the conger eel including head, fins and scales, 100g of conger eel meat was washed, filled into cans (Can No. ; 301-3) added with seasoning sauce 50g (Sample-1 ; Kochujang sauce, Sample-2 ; Chokochujang sauce, Sample-3 ; tomato paste sauce), respectively. All samples were seamed by using a vacuum seamer, and then sterilized at 118℃ for 40minutes using a steam system retort. Parameters such as microbial growth, proximate composition, pH, volatile basic nitrogen (VBN), thiobarbituric acid (TBA) value, amino-N content, salinity, color value (L, a, b), texture profile, total amino acid content, free amino acid content, mineral content and sensory evaluation of the 3 types of canned product were analysed according to the general methods. The moisture contents of Sample-1, Sample-2 and Sample-3 were ranged from 60.3 to 77.1g/100g, the crude protein content were 10.7 to 12.9g/100g, the crude lipid content were 3.8 to 5.6g/100g, respectively. Amino-N contents of Sample-1, Sample-2 and Sample-3 were 157.4, 172.8 and 186.3mg/100g, free amino acid content of samples were 366.6, 403.7 and 467.7mg/100g, respectively. As a result of the sensory evaluation, the shape, color and texture of Sample-1, Sample-2 and Sample-3 tend to be similar. But odor, taste and overall acceptance of Sample-3 were not estimated to be better than others.
