亚麻籽(Linum usitatisimum L.)用水提取种子，然后蒸发、乙醇沉淀、提取液冷冻干燥，制得胶粘剂。测定了聚合物的组成、溶解度、发泡性和吸湿特性。与市售的刺槐豆胶和瓜尔豆胶相比，这种胶水含有更少的碳水化合物，更多的矿物质和更多的蛋白质。其溶解度高于刺槐豆胶和瓜尔豆胶，低于阿拉伯胶。亚麻籽胶乳在质量分数为1.0%(w/v)的水溶液中具有良好的泡沫稳定性。当浓度高于0.2%(w/v)时，高度稀释的溶液表现出类似牛顿的行为，而剪切变稀。在pH为6.0~8.0的范围内粘度最大，在含有氯化钠的溶液中粘度降低。
Flax seed (Linum usitatissimum L.) mucilage was prepared by extraction of seeds with water followed by evaporation, precipitation with ethanol and freeze drying of extract. Proximate composition, solubility, foamability and moisture sorption characteristics were determined. The mucilage contained less carbohydrates, more minerals and more protein than commercial locust bean and guar gums. Its solubility, however, was higher than locust bean and guar gums, and lower than gum arabic. Flax seed mucilage exhibited good foam stability properties in aqueous solutions at 1.0% (w/v). Very diluted solutions exhibited Newtonian-like behavior while shear thinning was shown at concentrations above 0.2% (w/v). The viscosity was maximum at a pH range 6.0-8.0 and it was reduced in solutions containing NaCl.
