How to Extract Algal Oil

Rich in DHA and other omega-3 fatty acids, algal oil's potential uses have extended beyond those of the biofuel industry, providing the health-conscious with a source of healing and nutrition. Naturally occurring oils in algae (commonly referred to as seaweed) are extracted and made available through many health food distributors. There are several different methods used to extract the oil, most of which require chemicals and technologically advanced lab equipment. However, if you're curious about striking out on your own and pressing algal oils at home, using an expeller press (oil press) is the simplest way to extract the oils.

Instructions

• 1

  Wash the algae thoroughly to ensure it is free of debris. You can do this simply with clean water -- soap isn't needed.

• 2

  Dehydrate the algae (unless you purchased it already dried) using a drying rack or a dehydrator. With sufficient sunshine, the drying rack method should take three to five days. If you use a dehydrator, it should take from 30 to 60 minutes, depending on the thickness of the plant.

• 3

  Press the algae in the oil press and collect the oil in a sealable container for storage. Discard the pressed seaweed remains.
