Abstract: The present invention relates to methods for producing dairy food products modified with respect to their firmness and/or gelation time comprising cross-linked protein compounds and to methods for modifying said properties of said dairy food products, as well as to said modified dairy food products obtainable or obtained by such methods. Modification is achieved by in situ generation of H2O2 via carbohydrate oxidase, preferably cellobiose oxidase (EC 1.1.99.18), and cross-linking protein-tyrosine residues in a reaction using H202 via peroxidase (EC 1.11.1.7). Adding small phenolic compounds such as preferably p-coumaric acid or vanillin allows better control of the cross-linking reaction.

Abstract: The present invention relates to methods for encapsulating a bioactive agent such as a microorganism, methods for making a modified food, feed, cosmetic, plant health, seed health or pharmaceutical product comprising heteropolymer particles encapsulating a bioactive agent such as a microorganism, compositions and modified products comprising heteropolymer particles of a phenolic compound and a protein, and a bioactive agent encapsulated therein obtainable by such methods. Also provided is a method for delivering a bioactive agent to a subject, comprising administering to said subject the modified food, feed, cosmetic, plant health, seed health or pharmaceutical product described herein.
