Publication number: 20260078423Abstract: Provided is an N-acetyllactosamine-containing composition production method that achieves a higher rate of conversion from N-acetylglucosamine to N-acetyllactosamine as compared to conventional methods and that is simple but has no effect on the flavor. The production method provided is a method in which N-acetyllactosamine is produced using an enzyme reaction through the action of ?-galactosidase on lactose and N-acetylglucosamine, wherein the lactose concentration before the action of ?-galactosidase is 1.1 times or more the N-acetylglucosamine concentration in amount-of-substance ratio. An N-acetyllactosamine-containing composition produced by the production method is also provided, wherein the amount-of-substance ratio of N-acetyllactosamine (LacNAc) to N-acetylglucosamine (GlcNAc) (LacNAc/GlcNAc) contained in the composition is 0.26 or more.Type: ApplicationFiled: November 6, 2023Publication date: March 19, 2026Applicant: MEGMILK SNOW BRAND CO., LTD.Inventors: Junichi HIGUCHI, Toshiyuki YAMAGUCHI, Noriko NONOYAMA, Hirofumi FUKUDOME, Fumihiko SAKAI
