The lipase-catalyzed synthesis of fatty acid fructose esters in organic media and in supercritical carbon dioxide
Sugar fatty acid esters are biodegradable surface active compounds in foodstuffs and cosmetics or Pharmaceuticals. They have potential in replacing pollutant chemically synthesized surfactants. The enzymatic synthesis of fructose palmitate catalyzed by Candida antarctica B lipase was performed in di...
