Abstract
A low-mineral quark matrix 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 and/or a reverse osmosis step, producing a retentate R1, which represents a dairy protein concentrate, and a permeate P1, (c) subjecting the permeate P1 to an electrodialysis step, producing a salt-depleted diluate D1, (d) combining the diluate D1 with the retentate R1, (e) subjecting the combination product such obtained to heat treatment until denaturation sets in, (f) fermenting the denaturation product such obtained by the addition of starter cultures and rennet, and (g) adjusting or standardising the fermentation product such obtained to defined dry matter and protein contents.

A low-mineral quark matrix, obtained by the combination of the following order of processing steps:
- (a) subjecting raw milk to heat treatment, and separating the cream, to obtain a skimmed milk,
- (b) subjecting the skimmed milk such obtained to an ultrafiltration step and/or a reverse osmosis step, producing a retentate R1, which represents a dairy protein concentrate, and a permeate P1,
- (c) subjecting the permeate P1 to an electrodialysis step practically completely removing monovalent and divalent ions to produce a salt-depleted diluate D1, wherein said step (c) is the sole demineralization step occurring in said processing,
- (d) combining the diluate D1 with the retentate R1,
- (e) subjecting the combination product thus obtained to heat treatment until denaturation sets in,
- (f) fermenting the denaturation product thus obtained by the addition of starter cultures and rennet, and
- (g) adjusting or standardising the fermentation product thus obtained to defined dry matter and protein content,
- wherein the quark matrix thus obtained has a sodium content of below 50 ppm, 15-20% by weight dry matter content and 10-15% by weight protein content, both reduced sodium content and mineral content together with improved sensory taste properties being less bitter, less grainy, more fresh, more creamy and softer.
A process for the production of a low-mineral quark matrix, comprising the combination of the following order of steps:
- (a) producing a skimmed milk by heat treatment of raw milk and separation of the cream;
- (b) subjecting the skimmed milk thus obtained to an ultrafiltration and/or reverse osmosis step, obtaining a retentate R1, which represents a dairy protein concentrate, and a permeate P1,
- (c) subjecting the permeate P1 to an electrodialysis step practically completely removing monovalent and divalent ions to obtain a salt-depleted diluate D1, wherein said step (c) is the sole demineralization step occurring in said process,
- (d) combining the diluate D1 with the retentate R1,
- (e) heat treating the combination product thus obtained until denaturation sets in,
- (f) fermenting the denaturation product thus produced by adding starter culture and rennet,
- (g) adjusting or standardising the fermentation product thus obtained to defined dry matter and protein content, and
- (h) obtaining a quark matrix with a sodium content of below 50 ppm, 15-20% by weight dry matter content and 10-15% by weight protein content, both reduced sodium content and mineral content together with improved sensory taste properties being less bitter, less grainy, more fresh, more creamy and softer.
