Abstract:
1. A method for preparing a modified whey, comprising: a) removal of lactose from an unmodified initial whey by evaporation of the whey, to crystallize the lactose and to form a concentrated whey comprising from 55 to 70% dry matter, b) hydrolysis of the whey formed in a) with one or more lactases to reduce the lactose level to between 10 and 50% by weight of the quantity of lactose initially present in the unmodified initial whey, c) pretreatment of the proteins contained in the reduced lactose whey formed in b) by adding a calcium trap to said whey, in the hot state and at a substantially neutral pH, d) hydrolysis, in the hot state, of the pretreated proteins from c) by at least one endopeptidase, at least one exopeptidase and at least one molecule capable of cutting the disulfide bridges until a level of total proteins is at most 80% by weight of the initial weight of proteins present in the unmodified initial whey; and e) inactivation of all the enzymes present in the whey formed in d).
