Abstract

The invention pertains to a process for preparing a phenylalanine-free dietetic product comprising L-amino acids, and optionally comprising carbohydrates, minerals, trace elements and/or vitamins, for persons afflicted with phenylketonuria particularly adults, juveniles and pregnant women. The process comprises preparing a wet batch by dispersing in water the L-amino acids, some or all of the optional components, and at least one fatty material as an emulsifier, after which the wet batch is spray-dried. The spray-dried wet batch is then mixed with additional vitamins and/or carbohydrates and at least one fatty material as a separation agent to produce a mass. The mass thus produced is processed into cores for dragees or tablets, and the dragee or tablet cores are provided with coatings or dragee covers. The dietetic product is used as a nutrition supplement.
