Milkweed seed represents a potential alternative source of triglycerides for industrial application. Milkweed seed is harvested commercially for seed floss that is used as a hypoallergenic fiber fill material. The seed typically contains 25% triglycerides with 50% linoleic, 20% 18:1 (Delta9) and 14% 18:1 (Delta11). Press oil was generated by extruding raw seed with an Anderson Expander Cooker followed by expelling with an Anderson Lion 90-model expeller. Solvent extracted oil was generated by extrusion of the seed and then extraction with hexane in a Crown Model 2 Extractor. Residual oil measured 17.4% in the presscake and 9.5% in the solvent extracted meal. Press oil and solvent extracted oil were both refined using a modified caustic treatment. |
