How are rapeseed seeds extracted?
The rapeseeds were milled using a laboratory mill (A11 basic, IKA, Germany) and sieved into 1 mm fractions. The obtained fraction of seed material (about 20 g) was treated with petroleum ether (b.p. 60–90 °C) within 7 h. The extraction of the seed oil was done in triplicate. The oil content of the seeds was 40.9±0.1%.
How did rapeseed oil work?
