Abstract
The present invention pertains to a method of producing caseinomacropeptide (CMP)-containing compositions in high yield and having a very low content of phenylalanine (Phe). More specifically, the method involves subjecting a whey derived feed to a combination of ultrafiltration and subsequent cation exchange.
Claims13
A method of producing a caseinomacropeptide-containing composition having a low content of phenylalanine (Phe), said composition having a range of 0.1%-0.5% (w/w) Phe relative to the total amount of protein of the composition, the method comprising the steps of:
- a) providing a whey-derived feed comprising caseinomacropeptide (CMP) and at least one additional protein, said whey-derived feed having a pH in the range of 1-4,
- b) subjecting said whey-derived feed to ultrafiltration using an ultrafiltration filter (UF) allowing the passage of monomeric CMP, thereby providing a UF permeate and a UF retentate, which UF permeate is enriched with respect to CMP,
- c) contacting a first composition derived from said UF permeate with a cation exchange material, and
- d) collecting the fraction of the first composition which is not bound to the cation exchange material, thereby obtaining the CMP-containing composition.
