标题 :Method for producing taurine-enriched milk

摘要:The present invention relates to a method for the production of natural taurine-enriched milk using biological metabolism, in which a precursor for synthesis of taurine is prepared in the shape of a pallet or matrix resistant to degradation in the rumen of ruminants and added to a feedstuff, such that biosynthesis of taurine is induced by stimulation of a substrate. According to the method of the present invention, methionine or methionine precursor which is the precursor for taurine synthesis is coated with additives including an inert material and a filler, and thus protected from a rumen pH and an enzymatic action of rumen microorganisms. As a result, problems of the rumen degradation and the metabolism obstruction can be solved. Taurine-enriched milk according to the present invention contains taurine at a higher concentration than general milk, and hence, can be effectively used for the preparation of functional baby foods, and for the preparation of health foods.
