Abstract

The research of physico-chemical and organoleptic quality indicators of the black macrurus (grenadier) Coryphae-noides acrolepis caught under industrial conditions in the South Kuril subzone of the Sea of Okhotsk is presented. The analyzed samples included whole and eviscerated specimens of standard quality, as well as individual specimens with the consistency of muscle tissue characterized as «rubber-like». Comparative analysis showed statistically significant similarity of muscle tissue strength indicators before and after heat treatment, protein fraction content, moisture reten-tion capacity, degree of protein denaturation, enzyme activity and a number of other characteristics for standard sam-ples prepared by various methods and differing in size. Samples with a «rubber-like» consistency sharply differed in all the studied parameters except for enzymatic activity. When separating the proteins of black grenadier muscle tissue by electrophoresis was conducted, differences in the species-specific patterns of the compared samples were found. As-sumptions have been made about the causes of the detected changes.
