摘要:
There is provided a process for the prevention and/or reduction of acrylamide formation and/or acrylamide precursor formation in a foodstuff comprising (i) a protein, a peptide or an amino acid and (ii) a first reducing sugar; the process comprising the steps of: (a) contacting the foodstuff with a first enzyme capable of converting the first reducing sugar into a second reducing sugar; and (b) contacting the foodstuff with a second enzyme capable of oxidising a reducing group of the second reducing sugar.
摘要:
The present invention relates to the isolation of and characterization of a novel lipase inhibitor and its effect on different lipases. The present invention also relates to the use of a lipase inhibitor as a screen for lipases. The present invention also relates to the use of the inhibitor and/or lipases identified by a lipase inhibitor in food and/or feed technologies.
摘要:
A method of preparing a flour dough, said method comprising adding to the dough components an enzyme that under dough conditions is capable of hydrolyzing a glycolipid and a phospholipid, wherein said enzyme is incapable, or substantially incapable, of hydrolyzing a triglyceride and/or a 1-monoglyceride, or a composition comprising said enzyme, and mixing the dough components to obtain the dough.
摘要:
A method is described for releasing a soluble or membrane associated intracellular protein of interest (POI) comprising the steps of: providing a cell comprising a soluble or membrane associated intracellular POI; contacting the cell with a membrane extracting composition; and causing the POI to be released from the cell under conditions sufficient for the specific release of the POI and in a soluble form.
摘要:
The present invention provides methods and uses for treating pyropheophytin-containing compositions, particularly in order to remove pyropheophytin therefrom. The compositions are typically plant, algal, or bacterial derived products such as vegetable oils. The method comprises a step of contacting the compositions with an enzyme having pyropheophytinase activity. Also provided are related apparatus and products for performing such methods and uses.
摘要:
A polypeptide having lipase activity that retains at least 80 % activity after 4 days at 20 °C at a pH in the range of 3.5-8, retains at least 60 % of its activity after 1 hour at 60 °C in acetate buffer at pH 5.0, and has an isoelectric point in the range of 3.5-4.5. The polypeptide is useful as a dough and bread quality improving agent and it reduces crumb pore diameter, increases crumb pore homogeneity and improves the gluten index in doughs. The polypeptide is derived from fungi, yeast, bacteria, plant cells or animal cells and is produced in transformed host cells including filamentous fungi, e.g. Aspergillus tubigensis.

摘要:
There is provided an anti-fouling composition comprising (i) a surface coating material; (ii) an enzyme obtained or obtainable from a marine organism; and (iii) (a) a substrate for the enzyme; and/or (b) a precursor enzyme and a precursor substrate, wherein the precursor enzyme and the precursor substrate are selected such that a substrate for the enzyme is generatable by action of the precursor enzyme on the precursor substrate; wherein the enzyme and the substrate are selected such that an anti-foulant compound is generatable by action of the enzyme on the substrate.
摘要:
A method of improving the rheological properties of a flour dough and the quality of the finished product made from such a dough, comprising adding an effective amount of an oxidoreductase capable of oxidizing maltose, in particular a hexose oxidase, e.g. isolated from an algal species such as Iridophycus flaccidum, Chondrus crispus or Euthora cristata and a dough improving composition comprising the oxidoreductase.
摘要:
A process of forming a refrigerated dough is described. The process comprises admixing cereal flour and water with a protein that can reduce or prevent the enzymatic degradation of arabinoxylan present in the cereal flour.
