Use of secoiridoids, preferably oleuropein, for cross-linking biopolymers

摘要

The invention relates to the use of a secoiridoid-containing substance as a nontoxic cross-linking agent for the cross-linking of appropriate compounds including biopolymers, such as polypeptides and polysaccharides. Such biopolymers are particularly suitable in the production of food, feed, pharmaceutical and biomedical preparations, home and care products, and the like. Preferably, the cross-linking agent comprises an aglycone from a glycoside selected from the group of oleuropein, demethyloleuropein, verbascoside, ligustroside, and cornoside. Of these, oleuropein is preferred.
