Properties of refined milkweed press oil
2003
Holser, R.A.
The seed floss from Asclepias is currently harvested as a hypoallergenic fiber fill material for use in pillows and comforters. Milkweed seed is harvested with the floss although the oil contained in the seed is not used commercially. Milkweed oil was investigated as an alternative source of triglycerides for potential industrial applications. Processing conditions were investigated to produce degummed, refined, and bleached press oil. Milkweed oil was expelled from whole seed using a pilot-scale press and processed in the laboratory to produce refined and bleached oil. A high quality oil with a Lovibond color of 2Y and 0.2R was obtained following degumming with 3 wt.% water, refining with 3 M sodium hydroxide, and bleaching with 5% activated earth.
