    单硬脂酸甘油酯(E471) – Emulsifiers & stabilisers product from Bio Green Foods

    关于此产品

    单硬脂酸甘油酯是甘油与硬脂酸生成的非离子型酯,按 E471(脂肪酸单、双甘油酯)标示。产品为乳白色至淡黄色蜡状或粉状固体,无臭无味,凝固点 60-70C,由甘油与脂肪酸酯化制得,属植物基产品,所用脂肪酸来自棕榈。供应 40% 单甘酯牌号和蒸馏型 90% 牌号,25 kg 袋装。

    E471 是工业食品生产中的主力乳化剂,在每一类产品中承担的作用各不相同。在面包中,它与淀粉形成络合物以延缓老化:饱和的 C18 链嵌入直链淀粉螺旋内部,被包合的淀粉在面包冷却过程中不易重结晶,这正是工业面包能够数日保持松软的原因。在人造奶油和涂抹脂中,它位于两相界面,使水相保持分散状态,乳化体系在包装内不会破乳。在冰淇淋中,它控制脂肪去稳定化,把蛋白质从脂肪球表面置换下来,使脂肪球在搅打和冻结过程中发生部分聚结,形成赋予产品体态的脂肪网络;在充气甜点中,同样的界面作用可稳定泡沫。40% 与 90% 单甘酯牌号之间的选择是主要决策点。蒸馏型 90% 牌号每公斤提供更强的乳化能力,残留的游离甘油也少得多——最高 1.5%,而 40% 牌号为 7.0%——因此适用于添加量控制严格、或残留甘油会影响成品的场合。40% 牌号则是规格尚有余量的大宗应用中更经济的选择。

    主要用于烘焙制品的组织软化与抗老化、人造奶油与涂抹脂、冰淇淋与冷冻甜点、充气与打发类产品以及糖果。

    Bio Green Foods 以 25 kg 袋装供应单硬脂酸甘油酯,按牌号、单甘酯总含量、酸值、碘值、游离甘油和凝固点等规格供货。
