Assessment of biotechnological potential of king crab (P.camtschaticus) peeling waste

Abstract

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.
