    丙酸钙 – Food Preservatives product from Bio Green Foods

    关于此产品

    丙酸钙是丙酸的钙盐,分子式为 C6H10CaO4,CAS 号为 4075-81-4,欧盟添加剂编号为 E282。以白色自由流动粉末或颗粒形式供应,易溶于水,在使用水平下基本无气味。

    它成为面包主流防腐剂有其特定原因。多数食品防腐剂,包括苯甲酸盐和山梨酸盐,需要酸性环境才能发挥作用,在面包面团约 5.5 至 6 的 pH 条件下基本失效。丙酸盐在该 pH 下仍然有效。同样重要的是其选择性:它可抑制霉菌以及引起黏丝病(面包芯发黏、带有过熟气味的腐败)的枯草芽孢杆菌(Bacillus subtilis)菌株,而对酿酒酵母(Saccharomyces cerevisiae)影响相对较小,因此酵母仍能发酵,面团仍能醒发。一种会杀死酵母的防腐剂在发酵制品中毫无用处。面包中优先选用钙盐而非丙酸钠,因为它不引入钠并可补充钙;在钙会干扰化学膨松体系的场合,则使用丙酸钠。

    在面包、小面包、玉米薄饼、蛋糕和烘焙食品中的典型用量为面粉重量的 0.1 至 0.4%,此外还用于再制干酪和动物饲料。

    Bio Green Foods 按含量、游离酸和碱、干燥失重、氟化物和重金属指标的规格供应食品级丙酸钙。
