  • Late addition of PUFA in infant formula preparation process
    Patent number: 6428832
    Abstract: The present invention relates to a process for the preparation of a polyunsaturated fatty acid (PUFA)-containing food, such as an infant formula, where a composition comprising a PUFA is added at a late stage of the infant formula preparation process in this way, the PUFA's are minimally exposed to conditions during the process that induce degradation of the PUFA's.

  • PUFA coated solid carrier particles for foodstuff
    Patent number: 6048557
    Abstract: The present invention relates to a process for the preparation of a polyunsaturated fatty acid (PUFA)-containing composition where a PUFA-containing lipid is adsorbed onto a solid carrier, such as a powder. This can be used in a process for preparing an infant formula, such as where the powdered PUFA-containing lipid is added after an emulsion of oil and water phases has been formed.
