Abstract
Lactose containing physiologically-active sialic acids can be obtained by isolating and recovering the sialic acids together with lactose from a permeate or deproteinization solution obtained by ultrafiltration or heat treatment of whey or skim milk. The sialic acids-containing lactose is useful as an effective ingredient for foods, drugs, feeds, etc.
Claims7
A process for the production of sialic acids-containing lactose, which comprises the steps of subjecting a deproteinized solution having a 5-40% solids content obtained by subjecting sialic acids-containing whey or skim milk to ultrafiltration or to a heat treatment to remove proteins, to ion exchange by a cation-exchange resin and a strongly basic anion-exchange resin at a SV of 2-7 and a temperature of 5.degree.-50.degree. C., alone or in combination with electrodialysis, to desalt the solution to an extent of at least 80;
- and then concentrating the thus-desalted solution to a 10-50% solids content;
- and recovering the thus-produced sialic acids-containing lactose product.
