    明胶 – Hydrocolloids & Proteins product from Bio Green Foods

    关于此产品

    明胶由牛、猪或鱼的皮、革与骨中提取的胶原蛋白经部分水解制得。其 CAS 号为 9000-70-8,欧盟食品添加剂编号为 E441,以浅色颗粒、粉末或片状供应。A 型来自酸法预处理,通常以猪皮为原料;B 型来自牛皮和牛骨的碱法预处理。两者等电点不同,并非总能相互替代。

    按 Bloom 值分级,即压陷标准凝胶表面所需的力,商品级别一般为 80 至 300 Bloom。同等添加量下,Bloom 值越高凝胶越硬。凝胶形成的机理是溶液冷却时蛋白质链重新形成三螺旋结构,构成可截留水分的网络。由此产生两个结果。其一,该过程可热逆:凝胶受热熔化,冷却后重新凝固,这一点不同于果胶或淀粉凝胶。其二,也是商业上具有决定意义的一点,其熔点约为 35 摄氏度,略低于体温,因此可在口中溶化并释放风味,为其他任何水胶体所不及。新鲜菠萝、木瓜和猕猴桃含有蛋白酶,会阻碍凝固。

    用于糖果与软糖、甜点与慕斯、乳制品、肉制品、胶囊与片剂粘合,以及作为澄清剂。

    Bio Green Foods 按 Bloom 强度、黏度、水分、灰分、pH 值、微生物指标及动物来源的规格供应明胶,可提供清真与犹太洁食认证。
