Study on Four Detoxification Technologies of Flaxseed

Abstract

Abstract: Oven roasting, microwave roasting, autoclaving and water boiling methods were applied to remove cyanogenic glucoside from flaxseed, and their technical conditions were optimized. The optimum conditions of water boiling method are as follows: boiling temperature 100 ℃, material-water ratio 1:20 (W/V) and water boiling time 20 min. For oven roasting method, the optimum conditions are roasting time 20 min and roasting temperature 120 ℃. For autoclaving method, the optimum conditions are autoclaving time 25 min and autoclaving temperature 120 ℃. For microwave roasting method, the optimum conditions are output power for microwave roasting 640 Wand roasting time 2.0 min. Compared with the other methods, the water boiling method is the most suitable one for industreal production.

Key words: flaxseed, detoxification, cyanogenic glycoside
