Abstract: In this paper, linseed meal was processed by extrusion, microwave heating, autoclaving, microbe fermentation, water boiling and solvent extracting. The hydrogen cyanide (HCN) content in linseed meal was measured by alkaline titration. The effectiveness and mechanism of reducing the cyanogenetic glycoside of linseed meal were analyzed comparatively through different processing methods. The result showed that extrusion and microwave heating removed the cyanide in linseed meal effectively. The hydrogen cyanide content reduced respectively by 92.79% and 89.64% .It was propitious to exploit linseed meal for functional food.

Key words: linseed meal, cyanogenetic glycoside, detoxification, effectiveness, mechanism
