Process for preparing a fraction having a high content of alpha -lactalbumin from whey and nutritional compositions containing such fractions

A process for producing an alpha -lactalbumin-enriched fraction from whey is disclosed. The process involves heating pH-adjusted whey to a temperature sufficient to cause aggregation of beta -lactoglobulin molecules, and fractioning the whey using ultrafiltration or microfiltration, the alpha -lacta...

Zusammenfassung:	A process for producing an alpha -lactalbumin-enriched fraction from whey is disclosed. The process involves heating pH-adjusted whey to a temperature sufficient to cause aggregation of beta -lactoglobulin molecules, and fractioning the whey using ultrafiltration or microfiltration, the alpha -lactalbumin-enriched fraction obtained by the process is useful for making breast milk substitutes and other nutritional compositions.
