Beschreibung
Zusammenfassung:	A lactulose syrup containing more than 80 percent lactulose in total solid content, is produced in an industrially acceptable manner by admixing an aqueous solution of lactose with an aqueous solution of sodium hydroxide containing less than 0.54 percent sodium hydroxide based on the quantity of lactose, heating said mixed solution to a temperature of above 70 DEG C. to isomerize the lactose, and thereafter concentrating lactulose from the reaction liquid.
