Oil extraction by HHPE
Ten grams of papaya seeds were individually packed with
extraction solution (n-hexane) and hermetically sealed in high
density polyethylene bags. The samples were pressurized into the
same form as in Section 2.4.2. at 500 MPa for 5, 10 and 15 min. After
being extracted, the mixture was filtered under a vacuum, and the
solvent was removed with a rotary vacuum evaporator at 40 C.
Each extraction was performed in triplicate using three different
samples.
