3.2.2. Plant seed <strong>oil</strong> <strong>content</strong> determination<br />
Ten grams <strong>of</strong> seed flour were mixed with 10 g <strong>of</strong> fine s<strong>and</strong> <strong>and</strong> then extracted in Soxhlet. After eight<br />
hours the solvent was evaporated from the <strong>oil</strong>-solvent mixture in water bath <strong>and</strong> the solvent traces<br />
remaining removed in oven at 105 O C in a period <strong>of</strong> 20 minutes. The mass <strong>of</strong> the remaining <strong>oil</strong> was<br />
measured <strong>and</strong> the percentage <strong>of</strong> <strong>oil</strong> in the initial sample calculated using following formula:<br />
⎛ P ⎞<br />
% Oil = ⎜ ⎟x100 , where P = mass <strong>of</strong> <strong>oil</strong> <strong>and</strong> M = mass <strong>of</strong> plant seed flour used.<br />
⎝ M ⎠<br />
