Whey waa wax ka haray marka caanaha la qallajinayo inta lagu guda jiro geedi socodka soo saarista jiiska, waxaana ku jira wax kasta oo laga heli karo caanaha ka dib marka pH-ga hoos loo dhigo 4.6 inta lagu guda jiro geedi socodka qallajinta. Waa 5% xal of lactose in biyaha la lactalbumin iyo qaar ka mid ah lipid content. Geedi socodka waxaa lagu samayn karaa qalajinta fudud, ama content protein qaraabo la kordhin karaa iyadoo la saarayo lactose, lipids iyo waxyaabaha kale ee aan protein. Tusaale ahaan, qalajinta buufiyo ka dib filtration xuubka kala protein ka whey. Whey waxaa lagu kala saari karaa by kulaylka. kulaylka sare (sida heerkulka sare joogto ah ka sarreeya 72 ° C la xiriira habka pasteurization) denatures protein whey. Inkasta oo protein whey hooyo ma rennate ama acidification on denaturization of caanaha caanaha, protein whey triggers interactions hydrophobic la protein iyo waxyaabo kale, heerka waa in la gaadho si loo
72 °C
