Abstract: A quark matrix having improved taste characteristics is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to an ultrafiltration step, a microfiltration step, and/or a reverse osmosis step, producing a high-protein retentate R1 and a high-lactose permeate P1 in the process, (c) enriching the retentate with an amount of lactose which corresponds to the amount that had been separated in the ultrafiltration step as permeate before, (d) subjecting the enrichment product such obtained to heat treatment until denaturation sets in, (e) fermenting the denaturation product such obtained by adding starter cultures and rennet, and (f) adjusting the fermentation product such obtained to defined dry matter and protein contents.
