  • Publication number: 20110129569
    Abstract: The invention relates to a method for the preparation of fried vegetable products. In particular, it relates to a method for the preparation of fried vegetable products which have been subjected to an asparagine-reducing enzyme. The method comprises reducing the amount of enzyme product formed on the surface of the enzyme-treated vegetable material due to the action of the asparagine-reducing enzyme. If the amount of enzyme product is reduced before frying, this will contribute to the colour and the quality of the frying oil and of products subsequently fried in the oil and, thus, will minimize the loss of quality of the frying oil. The invention also relates to use of an asparagine-reducing enzyme preparation for preserving the colour of the frying oil.

  • Publication number: 20110124772
    Abstract: Polymers with non-leaching antimicrobial activity and their use as surface coatings or bulk resins for medical devices. The antimicrobial polymers are prepared with antimicrobial moieties covalently bonded to a polymer chain end or to a polymer backbone at a side chain end. The antimicrobial moiety-containing endgroups include surface active (or surface assembling) moieties which promote enrichment of antimicrobial endgroups at the polymer surface and thus formation of an antimicrobially active surface. Polymers with built-in antimicrobial endgroups can be used as bulk resins, as antimicrobial additives, or as infection preventative coatings in the manufacture of medical devices (e.g., catheters, vascular access devices, peripheral lines, IV sites, drains, gastric feeding and tubes, and other implantable devices).
