蜂蜡

关于此产品
蜂蜡由蜜蜂分泌用于筑造蜂巢,通过将蜂巢熔化并过滤而回收得到。它是一种复杂的天然混合物,主要由长链脂肪酸与长链醇形成的酯类组成,并含有游离酸和烃类,CAS 号为 8012-89-3,欧盟食品添加剂编号为 E901。
供应两种形态。黄蜂蜡(Cera Flava)仅经过过滤而未作其他处理,保留了蜂巢的颜色和特有的蜂蜜香气。白蜂蜡(Cera Alba)为同一材料经漂白而得,适用于涂层不得使浅色糖果或白色包衣片剂着色的场合。
在食品中,其作用在于表面而非基体。作为被膜剂,它形成一层薄的疏水膜,可减缓新鲜水果和奶酪的水分散失,防止糖衣糖果粘连和起霜,并赋予糖衣制品和包衣补充剂所需的光泽。同样的阻隔性能也是其用于口香糖胶基以及作为软膏载体的原因。
熔程(通常为 61-65°C)以及酸值和酯值是关键的规格指标,因为它们决定涂层的凝固方式及其在糖衣锅中的表现。请在询价时确认等级、产地,以及所需的是食品级规格还是药典规格。
