The article presents the technological potential research results of secondary resources formed in the King crab cutting process for food purposes. The authors analyzed waste (cephalothorax and abdomen) obtained from the King crab industrial processing from the North Okhotsk sea subzone and Primorye subzone. They determined the size and mass characteristics of waste. There is the shell, viscera (including liver), gills and abdominals ratio. A man examined the ratio of mineral (shell) and protein (interior and gills) parts of the studied waste experimentally. The research aim was to determine the total chemical composition, amino acid composition of proteins, fatty acid composition of lipids and mineral composition of the combined waste. The authors revealed that the secondary raw materials under the experiment consisted of the protein by 13.37 ± 0.05 %, lipids by 2.68 ± 0.1 %, minerals by 8.33 ± 0.25 % and carbohydrate compounds by 4.22 ± 0.05 %. The experiment determined the essential amino acids sum in the protein part. Valine, leucine and cysteine are limiting. Fatty acids in lipids waste are represented by polyunsaturated fatty acids in significant amounts (42.11 %). Calcium and sodium are overwhelming macronutrients in the waste from the King crab cutting, while iron and zinc are dominating microelements. The research results indicate the high technological value of waste from King crab cutting and the potential of this secondary raw material as a basis for the production of biologically valuable protein and mineral products.

The article presents the results of the study of the biotechnological and biogenic potential of king crab (P. camtschaticus) peeling waste, obtained during the production of boiled-frozen limbs. The waste used was a tadhopper shell and a conditionally protein portion (gills and insides) of the crab. It has been experimentally established that the proportion of the shell is about 60-65% of the weight of the waste, the proportion of the conditional protein-lipid part varies within the range of 30-35%. The waste contains proteins (13.37 ± 0,05%), lipids (2.68 ± 0,1%), minerals (8.14 ± 0,25%) and carbohydrates (4.22 ± 0,05%). Biological value of wastes is confirmed by data of amino acid composition of proteins, content of macro- and microelements and determination of relative biological value. Obtained results confirm high potential of king crab peeling waste as raw material for biologically valuable products.
