制备方法与用途

制备方法

一类由半乳糖单体组成的多糖，存在于多种植物种子和木材中。主要由β-1→4键合的D-吡喃半乳糖残基组成，同时有一部分由1→6键合的半乳糖残基。来自木材的半乳聚糖都属于半纤维素，果胶中的半乳聚糖一般以阿拉伯半乳聚糖的形式存在。琼脂也属于这类聚糖。

用途简介

• Barrier film-forming germicidal composition for controlling mastitis

  A long-lasting persistent, uniform film-forming skin protecting germicidal composition provides a long-lasting persistent barrier film when applied to skin. The compositions have particular utility as barrier teat dips for protecting cows against mastitis. A barrier film-forming agent is selected from the modified or hydrolyzed polysaccharides, particularly a hydrolyzed or modified starch, such as dextrin and maltodextrin. The barrier film-forming agent is stably solubilized in a solvent that dries to form the long-lasting persistent uniform film over the animal skin. The compositions also contain antimicrobial agents that fight against microbes that manage to penetrate the protective barrier film. Particularly, advantageous is that all the materials used are safe food additive and cost effective over the traditional barrier film forming agents.
