Seed galactomannans are vegetable, heterogeneous polysaccharides widely distributed in nature. Generally, they possess (1-->4)-linked D-mannopyranose (Man) main chains to which are attached (1-->6)-linked D-galactopyranosyl (Gal) units. The Man/Gal ratios differ from gum to gum, resulting in a change in structure, which, in turn, determines the various industrial applications of seed galactomannans. These materials are important in paper, textile, petroleum-drilling, pharmaceutics, food, cosmaceutics, and explosives industries. In this review, the biodiversified applicability of galactomannan gums is discussed, particularly with respect to structural aspects, properties, human consumption, and technical applications. Especially important is that the solution properties (rheological behaviour, viscosity, emulsifying tendency, etc.) of natural and chemically modified galactomannans can be tuned by interaction with other (carbohydrate-based) monomers or polymers.
种子半乳甘露聚糖是一类植物性的、异质的多糖，广泛分布于自然界。一般来说，它们具有以（1→4）连接的D-吡喃甘露糖（Man）为主链，其上连接着以（1→6）连接的D-吡喃半乳糖基（Gal）单元。不同种子胶的Man/Gal比例不同，导致结构发生变化，进而决定了种子半乳甘露聚糖的各种工业应用。这些材料在造纸、纺织、石油钻探、制药、食品、化妆品和炸药工业中都很重要。在这篇综述中，将讨论半乳甘露聚糖胶的生物多样性适用性，特别是在结构方面、性质、人类消费和技术应用方面。特别重要的是，天然和化学改性的半乳甘露聚糖的溶液性质（流变行为、粘度、乳化倾向等）可以通过与其他（基于碳水化合物的）单体或聚合物相互作用来调节。
