[PDF] acid and enzymatic hydrolysis

The key difference between acid hydrolysis and enzymatic hydrolysis is that acid hydrolysis is a chemical process, whereas enzymatic hydrolysis is a biochemical process. Hydrolysis refers to the cleavage of chemical bonds with the addition of a water molecule.

  • What is the difference between acid hydrolysis and enzymatic hydrolysis?

    Compared to traditional acid hydrolysis, enzymatic hydrolysis needs less energy and milder operational conditions (approximately under the temperature of 40–50°C and pH of 4–5) [19].

  • How does acid affect hydrolysis?

    A hydrolysis reaction is a reaction in which one molecule breaks apart to form multiple smaller molecules. Acidic hydrolysis of an ester gives a carboxylic acid and an alcohol. Basic hydrolysis (saponification) of an ester gives a carboxylate salt and an alcohol.

  • How does pH affect enzymatic hydrolysis?

    Enzymatic hydrolysis of nanofibrillated whey protein is affected by fibril solution pH. Degree of enzymatic hydrolysis increases by increasing the rate of fibril formation. Antioxidant activity of nanofibrillated whey protein hydrolysates is reduced at higher pH.
  • Utility cost of enzymatic hydrolysis is low compared to acid or alkaline hydrolysis because it is usually conducted at mild conditions and does not cause corrosion problems (Duff and Murray, 1996). Both bacteria and fungi can produce cellulases for hydrolysis of lignocellulosic materials.
