Abstract
A method of producing a low-lactose milk protein concentrate comprising the steps of providing a starting liquid milk protein concentrate, pre-treating the milk protein concentration by ultra-sonication, and treating the pre-treated milk protein concentration by diafiltration to provide a calcium depleted low-lactose milk protein concentrate. The process of the invention provides a milk protein concentrate with high levels of protein, less than 1% lactose, and a calcium level that is depleted by at least 20% compared with an untreated milk protein concentrate.

A method of producing a low-lactose milk protein isolate comprising the steps of:
- providing a starting liquid milk protein concentrate;
- pre-treating the starting liquid milk protein concentrate by ultra-sonication to provide a pre-treated milk protein concentrate;
- and
- treating the pre-treated milk protein concentrate by diafiltration to provide a calcium depleted low-lactose milk protein isolate.
A method of producing a low-lactose milk protein isolate comprising the steps of:
- providing a starting liquid milk protein concentrate;
- pre-treating the starting liquid milk protein concentrate by ultra-sonication to provide a pre-treated milk protein concentrate;
- and
- treating the pre-treated milk protein concentrate by diafiltration to provide a calcium depleted low-lactose milk protein isolate,
- in which the calcium depleted low-lactose milk protein isolate comprises more than 90% protein as a % of dry matter.
A method of producing a low-lactose milk protein isolate comprising the steps of:
- providing a starting liquid milk protein concentrate comprising as a % of dry matter 70-90% protein, 3-6% lactose and 2.3-4.0% calcium;
