  • Patent number: 10034485
    Abstract: Patatin, a lipase obtainable from potatoes, has been found to have advantages in the esterification reaction of fatty acids to yield fatty acid alkyl esters. Methods for application of this lipase activity are described, as well as the use of patatin in various industrial processes.
    Type: Grant
    Filed: July 3, 2013
    Date of Patent: July 31, 2018
    Assignee: COOPERATIE AVEBE U.A.
    Inventors: Robin Eric Jacobus Spelbrink, Marco Luigi Federico Giuseppin, Maarten Robert Egmond
  • Publication number: 20150189896
    Abstract: Patatin, a lipase obtainable from potatoes, is found to have specific selectivity for C4-C8 fatty acids, also when present in triglycerides. This makes patatin particularly suitable for hydrolysing triglycerides, such as present in milk fat, to enhance the flavour of food products. In particular, patatin is found to be beneficial in enhancing the flavour of cheese. Methods for application of the hydrolytic activity of lipase are described, as well as the use of patatin in a method of making cheese.

  • Patent number: 5858757
    Abstract: The invention relates to stabilized subtilisin proteases wherein one or more prolines is substituted for a native amino acid at stabilizing positions defined both by the range of the dihedral angles in the primary structure present at the substitution site and by selected characteristics of the protease secondary structure in the vicinity of the substitution site, to nucleotide sequences that encode the stabilized proteases, and to host organisms that contain the nucleotide sequences encoding the stabilized proteases.
