1. A method for producing a heat-treated concentrated dairy product (cdp), the method comprising the steps of:
passing a dairy product under a pre-determined pressure through a reverse osmosis filter at a first temperature within a range of 0 to 10° C. for a first period of time, the pre-determined pressure being sufficient to allow reverse osmosis, thereby concentrating the dairy product,
pre-heating the dairy product at a second temperature within a range of 95 to 125° C. for a second period of time within a range of 30 sec to 6 min to stabilize the dairy product,
homogenizing the dairy product to reduce a size of particles in the dairy product, and
heating the dairy product at a third temperature within a range of 120 to 140° C. for a third period of time to reduce microorganisms in the dairy product, thereby forming the heat-treated concentrated dairy product (cdp),
wherein the step of homogenizing the dairy product is performed prior to the step of heating the dairy product.
