Abstract: 

In this article, isomerization of lactose to lactulose using sweet cheese whey ultrafiltrate with sodium hydroxide as catalyst is studied. The effects of parameters such as the catalyst concentration, pH, reaction time and temperature, on the reaction rate and conversion of lactose to lactulose and byproduct formation were investigated. Also, purification of lactulose solution by ion exchange and crystallization was studied and a lactulose syrup with high purity was obtained.
