摘要
A process of obtaining a alpha -lactalbumin enriched product from whey of various origins is disclosed. A first ultrafiltration is carried out on unpasteurized raw whey with membranes having cut-off greater than 5,000 (e.g. 50,000) at a pH between 6.3 and 7 (e.g. 6.6) and a temperature between 30 DEG and 60 DEG C. thereby retaining whey proteins. The ultrafiltrate then undergoes a second ultrafiltration with a membrane capable of retaining alpha -lactalbumin (cut-off about 1,200 and 2,000) which is preferably diafiltration. Depending on whether starting whey is acid whey or sweet whey the resulting product may contain practically no CMP or some (e.g. 25%). The resulting product is useful as a mother's milk substitute, pharmaceutical, intensive care or therapeutic food, or tryptophan enriched nutrient.
