摘要：
1. A method of obtaining a dried modified whey protein concentrate (WPC) or whey protein isolate (WPI), comprising: (a) obtaining an aqueous solution of WPC or WPI having a protein concentration of 15-50% (w / v), pH 4.7-8.5； (b) heat treating the solution to a temperature above 50 ° C for a period of time allowing protein denaturation to occur； moreover, the heat treatment includes heating the solution under turbulent flow conditions； (c) at the end of the heat treatment, or transferring the heat-treated material directly to the dryer and drying the heat-treated WPC or WPI, moreover, the heat-treated WPC or WPI is not subjected to shear forces before drying, except for turning the liquid into droplets for facilitate drying； or direct transfer of the heat-treated material to a mixer for mixing with other ingredients, the heat-treated WPC or WPI not being reduced particle size to step c). 2. The method according to claim 1, wherein the turbulent flow has a Reynolds number of at least 500.3. The method according to claim 1, wherein the heat-treated WPC or WPI is spray dried. The method according to claim 1, wherein the heat-treated material is passed to mixing with at least one ingredient comprising at least one substance from the group consisting of milk, skim milk, fat, carbohydrate, milk retentate or skim milk retentate, heat-treated WPC or WPI is not subjected to shear forces before drying, other than dropping the liquid into droplets to facilitate drying. 5. The method according to any one of claims 1 to 4, in which the pH of the WPC concentrate is adjusted to between 5.0 and 8.5 before heating, preferably1. Способ получения высушенного модифицированного концентрата белка молочной сыворотки (WPC) или изолята белка молочной сыворотки (WPI), включающий:(a) получение водного раствора WPC или WPI, имеющего концентрацию белка 15-50% (вес./об.), при рН 4,7-8,5；(b) термообработку раствора до температуры выше 50°С в течение периода времени, позволяющего, чтобы произошла
