Maximum temperature for Omega 3?

I know that the essential fatty acid Omega 3 (found in flax seed oil, purslane and walnuts, etc) is heat and light-sensitive - but what oven temperature can it withstand, and for how long?

    Flaxseed Oil:

    is generally not recommended anything above 120degrees (fahrenheit). In fact, I believe flaxseed oil should be refridgerator to insure full maximum potency.

    Flaxseed: (dry flakes for baking)

    appears to be more withstanding.

    Thermal stability was shown in 1992 by the absence of significant changes in peroxide values and fatty acid composition when both forms of flaxseed were heated for 60 minutes at either 100°C (212°F) or 350°C (662°F). Furthermore, gas liquid chromatography showed no signs of new trans isomers of ALA or of cyclic fatty acid formation in samples subjected to these degrees of heat5. In a follow-up study the proportion of ALA in the fat of a muffin mix, where 28.5% of the formula was milled flaxseed, was virtually unchanged after baking at 178°C (350°F) for 2h (45.1% ALA before:45.0% after). This stability was observed even though oxygen consumption of the flaxseed muffin mix was considerably greater than that of the control muffin mix6. A subsequent study confirmed the stability of ALA in baked muffins containing the same amount of milled flaxseed and noted that thiobarbituric acid values, as estimates of ALA oxidation were also unaffected by baking9.
