Abstract
We studied fatty acid composition and the cholesterol content in total lipid extracts from the dorsal meat, abdominal meat, skin and viscera of cultured sturgeon (Bester sp.) by gas chromatography, and obtained the following results.
1) The lipid extracts per 100g of the abdominal meat was 5.1g, the dorsal meat 4.9g, the skin 3.3g and the viscera 4.4g.
2) Fatty acid composition of these samples was saturated fatty acids accounting for 23.3-28.5% monoenoic acids 43.2-53.7%, and polyenoic acids 17.9-30.8% respectively.
3) Fatty acids in the lipids from sturgeon parts mainly consisted of C16 saturated acid (13.9-19.0%) and C18 monoenoic acid (26.4-34.0%).
4) Cholesterol contents in the 100g samples were in the following order: dorsal meat (234mg)>abdominal meat (205mg)>skin (179mg)>viscera (41mg).
