The invention relates to a method for the preparation of hybrid cross-linked enzyme-silica aggregates including the steps of taking up enzyme molecules in a solvent, precipitating the enzyme molecules using a precipitation agent, and adding an alkoxysilane and crosslinking the mixture of alkoxysilane and precipitated enzyme aggregates, using a crosslinking agent comprising an aldehyde, to obtain hybrid crosslinked enzyme-silica aggregates.

This invention relates to inducible release vehicle comprised of crosslinked carbohydrates or proteins and an active ingredient. The release is induced by an external stimulus, e.g. an enzyme such as amylase. Such a vehicle can particularly be used in applications for preventing microbial decay or combating microbial infections. Other uses are for oral applications such as providing antdaries or flavoring compounds and for pharmaceutical and/or nutraceutical applications.

Inducible release vehicles

This invention relates to inducible release vehicle comprised of crosslinked carbohydrates or proteins and an active ingredient. The release is induced by an external stimulus, e.g. an enzyme such as amylase. Such a vehicle can particularly be used in an applications for preventing microbial decay or combating microbial infections. Other uses are for oral applications such as providing anti-caries or flavoring compounds and for pharmaceutical and/or nutraceutical applications.

The invention relates to a marking system for marking objects wherein said system comprises a microparticle comprising a cross-linked polymer and a marker component wherein the release of said marker component is triggered by contact of the microparticle with an external stimulus and wherein said polymer is a carbohydrate or a protein.

Method for marking materials

Described is a method for selectively isolating tryptophan containing peptides from an aqueous peptide mixture, including the steps of controlling the pH of the aqueous peptide mixture to 4.0-6.0, forming a precipitate of tryptophan containing peptides, and isolating the precipitated peptides. The aqueous peptide mixture is preferably obtained by enzymatic cleavage at acidic pH of a protein source. Further, peptides having a Trp content of 8-15 w/w % and the use thereof as a food additive and as an active ingredient in a medicament are described.

Method for preparing tryptophan rich peptides

Transglutaminase inhibitor containing composition obtainable from milk, in particular from a whey fraction obtainable from skimmed milk by forming a curd from the milk, separating the curd from the whey in a centrifugation step followed by subjecting the whey to an ultrafiltration step or, alternatively, by subjecting the skimmed milk to a diafiltration step, a method for the production of a transglutaminase inhibitor and the use of the transglutaminase inhibitor in the production of food or pharmaceutical compositions and to the use in the preparation of a medicament for the treatment of pathologies.
