Claim 0:
1. A method for producing a mildly-heated treated bioactive sweet whey WPC80 preparation comprising a high level of bioactive compounds with reduced denaturation and aggregation, said method comprising the sequential steps of:
a) providing a sweet whey;
b) applying a first heat-treatment of the sweet whey between 60° C. and 68° C. for between 10 and 20 seconds, wherein the heat treatment is for reducing cheese starter culture bacterial growth and preventing further pH drop in the whey;
c) cooling the sweet whey to a temperature of 5° C. to 18° C.;
d) applying a separation and/or concentration step at 5° C. to 18° C., which separation is ultrafiltration and which concentration is reverse osmosis or nano filtration to obtain WPC35;
e) applying a micro filtration on the retentate from step d) to prevent particles from entering into the permeate, wherein the particles are sediment, algae, protozoa or large bacteria;
f) applying a separation on the permeate from step e) at 5° C. to 18° C. to obtain WPC80, and wherein, the separation is ultrafiltration;
g) applying a second heat-treatment of between 60° C. and 65° C. for between 10 and 20 seconds on the retentate of step f);
h) optionally, cooling the product obtained in g) to less than 15° C. for storage of the bioactive sweet whey WPC80 preparation; and
i) optionally drying said product, thereby obtaining a dried bioactive sweet whey WPC80 preparation.
