Abstract: A protein composition and a baby food (infant formula) containing this are provided. The protein composition is characterised in that it contains at least 15 wt % (based on the total amount of the proteins) modified proteins, the course of whose digestion is slowed compared to the unmodified, normal proteins serving as starting materials. Such a protein composition and a baby food containing this create just as good metabolic conditions for the normal development of a child as feeding with human milk proteins.

Abstract: A whey protein dominant baby food is prepared that may contain hydrolysed food with a reduced threonine content. This food can be obtained by adding glycomacropeptide-free or glycomacropeptide-reduced whey powder and/or whey protein concentrate as the whey proteins usually used in the production of milk baby food.

Abstract: A phenylalanine-free nutrient base for infants and small children, sad also a process for the production thereof, are provided. This nutrient base, in addition to an amino acid mixture which has all L-amino acids necessary for the nutrition of the child, except for phenylalanine, also contains fats sad/or carbohydrates sad also, optionally, minerals and/or trace elements. This nutrient base is produced by spray-drying of an aqueous formulation containing these components. During this, at least the amino acids lysine and cystine are at least in part mixed into the spray-dried product obtained after the spray-drying. Owing to the fact that these amino acids are not spray-dried with the others, the end product obtained is free of undesired by-products that form during spray-drying.

Abstract: In the method of the invention to obtain lipids with a high proportion of long-chain polyunsaturated fatty acids (LCPs) with 20 to 22 carbon atoms by extraction from a raw material of animal or vegetable origin, unicellular algae (microalgae), macroalgae from the families of the brown, red and green algae and/or residues of alginate or carrageenin production with a water content of .ltoreq.50 weight % and a particle size of .ltoreq.50 mm are used. For extraction, an organic solvent or a compressed gas is used. A lipid extract with a high proportion of w6 LCP and w3 LCP and in particular with a content of at least 5 weight % of arachidonic acid and/or a content of at least 3 weight % of docosahexanoic acid is also prepared.

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.

Abstract: The present invention relates to a process for the production of liquid and powdered bifidogenic infant and dietetic foods which are reduced in their antigenicity. The process according to the invention is characterized in that to achieve bifidogenicity, sialic acid is enzymatically cleaved from the milk proteins using the enzyme neuraminidase (sialidase).Consequently in accordance to the invention it is possible to produce bifidogenic infant foods, particularly suitable for infants, premature and small for date babies, which can additionally be used in cases of intolerances against usual milk products.Furthermore the process can be used for production of dietetic food, particularly for patients suffering from intestinal allergies, other allergic diseases and patients with insufficiency of liver and kidney.
