    玉米淀粉 – Sweeteners & Starch Derivatives product from Bio Green Foods

    关于此产品

    玉米淀粉采用湿法研磨从 Zea mays 的胚乳中提取,浸泡后的籽粒在该工艺中被分离为淀粉、蛋白质、纤维和胚芽。其 CAS 号为 9005-25-8,以细白粉末形式供应。其化学组成为两种葡萄糖聚合物的混合物:直链淀粉,基本呈线性的链状分子,约占淀粉的四分之一;支链淀粉,高度支化的分子,占其余部分。

    天然状态下,淀粉以半结晶颗粒形式存在,不溶于冷水。将悬浮液加热至约62至72摄氏度以上,会破坏维系这些颗粒的氢键;颗粒吸水、显著膨胀并最终破裂,使聚合物链释放到溶液中。这一过程称为糊化,是酱汁增稠的原因,且不可逆。冷却并静置后,线性的直链淀粉分子重新排列并再次排出水分,这一称为老化(回生)的过程,正是淀粉增稠的酱汁在冷藏时变浑浊并析水、面包变陈的原因。长时间加热、高酸度或剪切作用会使分子链断裂,导致体系变稀。

    它用作汤品、酱汁、肉汁和甜点的增稠剂,用于烘焙和糖果制品,用作粘合剂和撒粉剂,以及作为生产葡萄糖、麦芽糊精和变性淀粉的原料。

    Bio Green Foods 按水分、淀粉含量、蛋白质、灰分、pH 值、白度和二氧化硫的规格供应食品级玉米淀粉。
