Egg yolk having a high level of natural antisecretory proteins, process for its preparation and food or pharmaceutical product containing thereof

摘要

The present invention relates to egg yolk having a high level of natural antisecretory proteins (NASP) corresponding to 100 and preferably at least 10,000 FIL units/ml. The invention also relates to a process for its preparation being characterized in that an egg-producing bird, particularly a gallinaceous bird is fed by a feedstuff, for instance a malted cereal containing amino acids sugars and amides in an amount such that the formation of NASP is stimulated. The invention further relates to the use of such egg yolk in the preparation of functional food products enriched with NASP or pharmaceutical products intended for the treatment and prophylaxis of disease-like conditions caused by extreme loss of body fluids. Also disclosed is a food or pharmaceutical product containing the above-described egg-yolk or NASP obtained therefrom.
