    丙酸钠 – Food Preservatives product from Bio Green Foods

    关于此产品

    丙酸钠是丙酸的钠盐,分子式为 C3H5NaO2,CAS 号 137-40-6,欧盟食品添加剂编号 E281。以白色结晶粉末或颗粒供应,易溶于水,溶解度明显高于钙盐。

    其抗菌机理与所有丙酸盐相同:未解离的丙酸穿过微生物细胞膜并破坏其内部代谢,对霉菌以及引起面包黏丝(绳状)变质的芽孢杆菌菌株作用最强,而对面包酵母影响相对较小。它在面团接近中性的 pH 条件下仍保持活性,而苯甲酸盐和山梨酸盐在此条件下则无效。选择钠盐而非丙酸钙的理由具体而实际:在蛋糕、苏打面包和部分饼干等化学膨松产品中,添加的钙离子会干扰化学膨松反应,可能降低产气量和体积。丙酸钠可避免这一问题,代价是引入钠。其较高的溶解度也适合液体添加和盐水体系。

    用于化学膨松的蛋糕和烘焙食品、面包和小面包、玉米薄饼、再制干酪,以及作为饲料防霉剂。

    Bio Green Foods 按含量、游离酸与游离碱、干燥失重、铁和重金属等指标供应符合规格的食品级丙酸钠。
