List Docs
  • Glucose and Galactose are the hydrolysis products of lactose.

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

    Hence the product obtained by hydrolysis of lactose is β-D galactose and β-D glucose.

  • What does lactose on hydrolysis with acids give?

    Beta-galactosidase catalyses the hydrolysis of lactose into galactose and glucose.

  • What is the acid catalyzed hydrolysis of lactose?

    In water, lactose undergoes acid-catalyzed hydrolysis to produce glucose and galactose in near quantitative yield (activation energy 135.5 kJ mol1).

  • 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.
