Benefits of technology

[0002]The present disclosure relates to a method for producing fresh milk having a longer shelf life.
[0003]In a general method for producing drinking milk, see FIG. 1, raw milk is first heated to a preset skimming temperature. This can be, for example, between 55 and 62° C., in order to prevent protein damage.

Problems solved by technology

Usually, high-temperature heat-treated milk, however, exhibits significant taste differences compared with fresh milk.
Such a milk, however, cannot be termed fresh milk.
This has the disadvantage that the cream fraction either has a high fraction of spores or, on account of heating, only has a low fraction of β-lactoglobulin.
Precisely this aerobic spore former increases a hundred fold in a period of 6 days and impairs to a great extent the shelf life of the milk owing to sweet curdling.

Embodiment Construction

[0054]FIG. 1 shows a flow chart of a known production process for producing fresh milk.

[0055]Stored raw milk 100 at a temperature of 2-8° C. is warmed or warmed up using a plate heat exchanger in step 200 to a skimming temperature of 50-60° C., for example, 55° C. Then, the raw milk is centrifugally separated in a separator into cream 310 and skimmed milk 360 in step 300. Or, the milk is skimmed. The cream 310 is then, according to the desired cream content of the milk, divided in step 320, where excess cream, step 340, can be stored, step 350, if desired. Then, the cream is homogenized in step 330 in such a manner that a breakdown of fat balls for stability against creaming results.

[0056]The skimmed milk, step 360, is then mixed with the desired amount of cream, standardized, and in step 400 warmed or short-time heated to a temperature of 70-80° C., or, for example, 74° C. That is done by way of a plate heat exchanger, and in step 500 kept hot for a correspondingly long time. At th...

Abstract

A method for producing fresh milk having a longer shelf life. The method steps include: providing raw milk; and performing an at least two-step centrifugal germ removal process of the raw milk before a standardization process of the raw milk is carried out. A method may also include performing a first step of a two-step centrifugal germ removal process before a skimming process separating skimmed milk is carried out and performing a second step of the two-step centrifugal germ removal process during the carrying out of the skimming process separating skimmed milk.

Description

[0001]This application is a national stage of International Application PCT / EP2010 / 063511, filed Sep. 15, 2010, and claims benefit of and priority to German Patent Application No. 10 2009 044 030.5, filed Sep. 16, 2009, the content of which Applications are incorporated by reference herein.BACKGROUND AND SUMMARY[0002]The present disclosure relates to a method for producing fresh milk having a longer shelf life.[0003]In a general method for producing drinking milk, see FIG. 1, raw milk is first heated to a preset skimming temperature. This can be, for example, between 55 and 62° C., in order to prevent protein damage.[0004]After the skimming, that is to say separating the raw milk into cream and skimmed milk, the cream is homogenized.[0005]Then the skimmed milk is optionally standardized by adding a predetermined amount of homogenized cream.[0006]Hereafter, the standardized and homogenized milk must be pasteurized at a temperature between 72° C. and 75° C. and for a treatment time of...
