| Abstract: | The flaxseed gum was extracted from flaxmeal with water in this paper.By using single-factor and orthogonal experiments,the optimum conditions of extraction were obtained as follows: the ratio of material to liquid,1∶125,extraction temperature,70 ℃,extraction time,90 min,and washing for 1 time.Under these conditions,the extraction rate of flaxseed gum could amount to 32.0%.The effect of concentration,pH,temperature on the viscosity of flaxseed gum solution and the effect of concentration on the rate of emulsion were also studied. |

| Keywords: | flaxmeal flaxseed gum extraction viscosity emulsification rate |
