[PDF] acid hydrolysis of lactose

Hydrolysis of lactose in whey (both acid and sweet) and aqueous solutions was unsuccessful at pH 4.7 and 90 C being less than 1% after 96 h of heat treatment. Hydrolysis was also insignificant in acid whey and aqueous lactose solutions containing 5 and 10% lactic acid after treatment for 150 h at 60 C.

  • What product will be produced by acid hydrolysis of lactose?

    The products of hydrolysis of lactose are ?-D-Glucose and ?-D-Galactose.

  • Does acid break down lactose?

    The enzymes in a perforated lactic acid bacteria breaks down lactose into its constituent sugars: galactose and glucose. As such, the milk becomes lactose-free.

  • What happens to lactose during hydrolysis?

    The hydrolysis of lactose gives galactose and glucose.
  • Lactose can be hydrolyzed by two principal methods, using acid treatment at high temperature (above 150 °C) or enzymatic catalysis. The second one is preferred because of its milder operating temperature and pH.
