摘要：
In a method of purifying whey separated from lactic acid fermentation liquid by electrodialysis wherein said whey contains angiotensin-converting enzyme inhibiting peptides, the improvement which comprises using an anion exchange membrane having a permeability of diffusion coefficient in the range of 3.0 to 9.0×10−6 cm/sec. An anion exchange membrane having a permeability of diffusion coefficient in the range of 5.0 to 7.0×10−6 cm/sec. is more efficiently used. The product is particularly suited to produce granules and tablets.
