产品应用

  • Amylopectin is a glucose-based, highly-branched polysaccharide which together with amylose makes starch. The glucosidic bonds of amylopectin are α-1,4 in the glucan chain and α-1,6 at the branch points. Amylopectin from maize differs in structure form amylopectin from other plant species and is used in the study of the development of starches.

其他信息

  • 支链淀粉白色粉状,又称胶淀粉。支链淀粉是以优质糯玉米为原料生产的一种纯天然支链淀粉。与普通淀粉相比具有较高的膨胀性、粘滞性和透明度,其膨胀性是普通淀粉的2.7倍。普通淀粉溶液很不稳定,贮存时逐渐变成混浊,胶粘性降低,最后出现白色结晶沉淀。而支链淀粉很容易溶于水生成稳定的溶液,且具有很强的粘度,不易发生老化,淀粉液在贮存过程中,不发生沉淀。
