Abstract

Pasta filata cheese products of the Mozzarella type are suggested, obtainable or obtained by:
(a) subjecting milk to bactofugation or filtration, obtaining a bactofugate or a bacterial concentrate and a treated milk; (b) sterilising and, optionally, standardising the bactofugate or the bacterial concentrate obtained in step (b); (c) blending the treated milk of step (a) with the sterilised bactofugate or the bacterial concentrate of step (b); (d) coagulating the blended product of step (c) while adding starter cultures and/or rennet; (e) separating the coagulated milk of step (d) into whey and curd; (f) processing the whey with fine curd particles contained therein obtained in step (e) into a stable suspension; (g) subjecting the curd obtained in step (e) to heat treatment, and (h) shaping the heat-treated product of step (g),

wherein the suspension produced in step (f) is either added to the bactofugate or the bacterial concentrate obtained in step (a), or to the sterilised bactofugate or the bacterial concentrate obtained in step (b).

First claim

The invention claimed is:

1. A process for the production of pasta filata cheese products of the Mozzarella type, comprising the following steps:
(1) processing a whey obtained from coagulation of cheese milk into a stable suspension, wherein
whey is wholly or substantially separated,
resulting dry, or substantially dry, curd particles are re-suspended in water or in another dairy product,
a suspension such obtained is subjected to homogenization, and
said suspension contains particles having a diameter of less than 250 μm;

(2) providing a milk;
(3) subjecting the milk to bactofugation, obtaining a bacterial concentrate and a treated milk;
(4) adding the suspension produced in step (1) to the bactofugate obtained in step (3) and sterilizing the thus-obtained mixture;
(5) re-adding the mixture of step (4) to the treated milk obtained in step (3);
(6) coagulating the milk of step (5) while adding starter cultures and/or rennet material;
(7) separating the milk coagulated in of step (6) into whey and curd;
(8) heat treating the curd obtained in step (7); and
(9) shaping and cooling the product heat-treated in step (8),
wherein the whey obtained in step (7) is further processed to the stable suspension of step (1).

2. The process of claim 1 , wherein raw milk, semi-skimmed milk or skimmed milk is employed.

3. The process of claim 1 , wherein the milk is standardised by adding cream, skimmed milk, whey cream, buttermilk or milk protein concentrate.

4. The process of claim 3 , wherein the milk is adjusted to a fat-to-protein ratio of about 0.2 to about 1.2.

5. The process of claim 3 , wherein the standardised milk is subjected to bactofugation.

6. The process of claim 1 , wherein homogenisation is performed mechanically and/or thermally and/or (bio)chemically.

7. The process of claim 6 , wherein homogenisation is performed by cavitation.

8. The process of claim 1 , wherein said suspension contains particles having a diameter of less than 150 μm.

9. The process of claim 1 , wherein said suspension has a portion in solid curd particles within the range of about 0.1 to about 10% by weight.
