Flax Oil
Like
flax
oil,
hemp oil should be stored
in the refrigerator, used quickly, and never heated.
Unless you get flax oil right from the processor and freeze it
until you start using it, it will already have deteriorated
by the time you buy it.
For dietary purposes flax oil must be pressed
at low temperatures, protected from light, heat, and air,
stored at cool temperatures, and used quickly
once the containers are opened.
Most flax oil is not delicious.
There is great variation in taste among
the brands currently sold in natural food stores,
but the best of them still leaves much to be desired.

says that the problem is freshness.
Unless you get flax oil right from the processor and freeze it
until you start using it, it will already have deteriorated
by the time you buy it.
Flax oil is pressed from the seeds of
linum utilitatissimum,
the source of linen fiber and an oil better known
in this country as linseed oil, the base for oil paints.
Linseed oil is usually classified as a "drying oil"
rather than a food oil because its chemical
characteristics cause it to combine readily
with oxygen and become thick and hard.
This tendency to harden on exposure to air
quickly turns linseed oil rancid and unfit to eat,
but makes it useful as a vehicle for pigment on canvas.
(The word "canvas" by the way is a relative of "Cannabis,"
because true canvas is made from hemp fiber.)
