Технохимическая характеристика морских звезд как объекта промышленной переработки

Abstract

Представлены результаты исследования размерно-массовых характеристик и химического состава морских звезд, наиболее распространенных в бухте Северной зал. Петра Великого Японского моря на морских плантациях Дальрыбвтуза. Эвастерия колючая и патирия гребешковая достигают максимального размера в весенне-летний период. Большую часть тела морских звезд, независимо от сезона вылова и вида, составляет покровная ткань. Исследование общего химического состава морских звезд подтверждает целесообразность промышленного использования этих объектов. В них содержатся белки (9,5-14,3 %), липиды (0,7-3,8 %), минеральные вещества (1,3-32,0 %). По сравнению с покровной тканью внутренние органы обоих видов звезд отличаются высоким содержанием калия и железа. Биологическая ценность объектов оценена качественным составом белков и липидов. Установлено, что белки обеих морских звезд содержат все незаменимые аминокислоты. Их общее количество в покровной части звезд составляет 36,4-39,4 % суммы аминокислот, во внутренностях патирии гребешковой и эвастерии колючей соответственно 40,3 и 44,3 %. В липидах морских звезд на долю насыщенных жирных кислот приходится 20,7-22,7 %. Полученные данные подтверждают высокую биологическую ценность изучаемых объектов и предопределяют возможность получения из морских звезд биологически ценных кормовых продуктов.

Size-weight parameters and chemical composition of starfish from the Severnaya Bay (Peter the Great Bay, Japan Sea) are investigated. Two starfish species: Evasterias echinosoma and Patiria pectinifera form dense aggregations in the bay at aquaculture plantations of Far-Eastern Technical University. Their largest size and weight are observed in spring and summer. The main part of their body weight is presented in any season by coating connective tissue that contains proteins (9.5-14.3 %), lipids (0.7-3.8 %), and mineral substance (1.3-32.0 %). The proteins include all essential amino acids (36.4-39.4 % of total amino acids weight) and the lipids include unsaturated fatty acids (20.7-22.7 % of total lipids weight). Viscera of starfish are distinguished by high content of potassium and iron and the proteins of viscera have heightened content of essential amino acids (on average 40.3 % of total amino acid weight for P. pectinifera and 44.3 % for E. echinosoma ). High biological value of the starfish tissues determines prospects of their use as raw material for industrial processing to functional foodstuffs.
