深度水解蛋白配方奶(extensively hydrolyzed protein formula,eHF)是将牛奶蛋白通过酶切水解、加热、超滤等工艺处理,使其形成二肽、三肽及少量游离氨基酸。eHF所包含的肽中95%以上分子量低于3 000 D,使牛奶蛋白的抗原性明显降低,最初用于治疗牛奶蛋白过敏的婴儿。理论上,短肽及氨基酸较整蛋白更易消化吸收,适合早产儿消化系统 The extensively hydrolyzed protein formula (eHF) is a dipeptide, tripeptide and a small amount of free amino acids that are processed by enzymatic cleavage, heating and ultrafiltration. More than 95% of the peptides contained in eHF have a molecular weight of less than 3,000 D, which significantly reduces the antigenicity of milk proteins and was originally used to treat infants with milk protein allergies. In theory, short peptides and amino acids more digestible than the whole protein absorption, suitable for premature infant digestive system
