    聚甘油脂肪酸酯(E475)

    📦

    关于此产品

    聚甘油脂肪酸酯,E475,常缩写为PGE或PGFE,是把甘油聚合成二到十个单元的短链,再与脂肪酸酯化得到的。根据链长和所用脂肪酸的不同,产品从油状液体到蜡状固体不等。

    这一族之所以有用,在于它的性质是设计出来的而不是天生固定的。每增加一个甘油单元就多出一些羟基,把分子推向水一侧;每增加一条或加长一条脂肪酸链,又把它推回油一侧。因此同一套化学可以做出HLB从约3到约13的产品,这也是为什么同一个E编号涵盖了作用相当不同的乳化剂。三聚甘油单硬脂酸酯处在亲油一端,用于控制人造奶油和起酥油中的晶粒大小;十聚甘油酯处在亲水一端,在蛋糕凝胶和打发制品中充当充气和发泡剂。聚甘油蓖麻醇酸酯,也就是E476的PGPR,是这一族中最知名的亲戚:只需千分之几就能把熔融巧克力的屈服值压下来,从而让巧克力在浇模线上顺畅流动,而不必添加昂贵的可可脂。对配方师而言,关键在于决定效果的是牌号而不是E编号,因此聚合度和脂肪酸种类必须在订单中写明。

    用于蛋糕凝胶和充气面糊、打发涂层和馅料、巧克力与代可可脂涂层的黏度控制、人造奶油和起酥油的晶型改良,以及饮料和香精乳液的乳化。

    Bio Green Foods 供应聚甘油脂肪酸酯,按聚合度、脂肪酸类型、HLB、羟值和酸值规格执行,20公斤或200公斤桶装。请说明用途,合适的牌号由此确定。
