the composition of muscle tissues of a deep-sea species, the giant grenadier(Albatrossia pectoralis), and a mesopelagic species, the Alaska pollock(theragra chalcogramma), are compared. Grenadier is proved to have a higher moisture cont.n.(91.7%) and lower protein(7.4%) and lipid(0.3%) cont.n.s. the factors responsible for the soft.n.ng and moisture separation during processing of grenadier are identified. Cont.n.s of some fractions of non-protein nitrogenous components, including trimethylamine oxide(tMAO) and free amino acids, are clarified. the proportion of the main myofibrillar proteins myosin and act.n. which is considered as an indicator of efficiency of structure formation in fish muscle tissue during processing, is almost 20% lower in giant grenadier than in pollock. the effects of endogenous protease, Са^2+-AtPase and transglutaminase on the processes of autolysis, denaturation, and possibility of myofibrillar proteins cross-linking were also studied. the proposed technology of gett.n. a nutritionally balanced, gel-like, ready-to-use foodstuff from grenadier fillet includes its enrichment with pollock muscle tissue and supplement.n. with a binary structure-forming agent containing collagen and chitosan. nutritional value of the products is assessed by the method of biological assay and by determining the denaturation changes of myofibrillar proteins. the modes of fine mincing and thermal processing, as well as the shelf-life of the finished product are justified. the developed technology of producing a ready-to-eat food from giant grenadier will allow a more efficient use of this underutilized resource.
