Flaxseed contains significant concentration of mucilage or gum (a type of hydrocolloid). Flaxseed mucilage (FM) predominantly occurs in the outermost layer of the seed's hull and is known to possess numerous health benefits such as delayed gastric emptying, reduced serum cholesterol, and improved glycemic control. FM is typically composed of an arabinoxylan (neutral in nature) and a pectic-like material (acidic in nature). Similar to gum arabic, FM exhibits good water-binding capacity and rheological properties (similar functionality); therefore, FM can be used as its replacement in foods. In this review, an overview of methods used for FM extraction and factors influencing the extraction yield were discussed initially. Thereafter, food applications of FM as gelling agent/gel-strengthening agent, structure-forming agent, stabilizing agent, fat replacer, anti-retrogradation agent, prebiotic, encapsulating agent, edible coatings and films/food packaging material, and emulsifier/emulsion stabilizer were included. At the end, some limitations to its wide application and potential solutions were added.
亚麻籽含有大量的黏液质或树胶（一种水胶体）。亚麻籽黏液质（FM）主要存在于种子外壳的最外层，已知具有多种健康益处，如延缓胃排空、降低血清胆固醇和改善血糖控制。FM通常由阿拉伯木聚糖（性质为中性）和类果胶物质（性质为酸性）组成。与阿拉伯树胶类似，FM具有良好的水结合能力和流变学特性（类似的功能）；因此，FM可在食品中用作其替代品。在这篇综述中，首先讨论了用于FM提取的方法以及影响提取率的因素。此后，还介绍了FM在食品中的应用，如胶凝剂/凝胶强化剂、结构形成剂、稳定剂、脂肪替代品、抗老化剂、益生元、包囊剂、可食用涂层和薄膜/食品包装材料以及乳化剂/乳液稳定剂。最后，还补充了其广泛应用的一些局限性和潜在解决方案。
