[Extractability of lipids from fish and fish products]

The completness of the lipids removal from the fish muscles and fish products was investigated by making extraction in a filtering separating funnel (FSF) formerly proposed for determining lipids in oil-bearing seeds and cereals. The new modified procedure was contrasted against the standard one (accepted by the State Standards) used in separating and quantitative determination of the lipids content in fish by using the Socklet apparatus for extraction. The proposed variant of extraction was found to secure a higher yield of the lipids. The pattern of analysis used in determining the lipids content in vegetable products may well be used also in investigating animal products, such as, fish and fish products.
