Abstract
Disclosed is process for producing milk and milk-related products with extended shelf life. The process comprises the steps of separating whole milk is a cream fraction and a skimmed milk fraction, wherein the skimmed milk fraction has a fat content of 0.5% by weight or less, subjecting the skimmed milk fraction to a heat treatment, said heat treatment comprising heating the skimmed milk fraction to 152° C. to 165° C. for 500 ms or less, and cooling of the skimmed milk fraction to a temperature at or below 70° C. The produced milk and milk-related products maintains a high degree of undenatured whey protein despite the high treatment temperature.
Claims17
A process for producing a skimmed milk fraction comprising the steps of:
- a. separating a whole milk as a cream fraction and a skimmed milk fraction, wherein the skimmed milk fraction has a fat content of 0.05%-0.5% by weight and the skimmed milk fraction being subjected to a pre-treatment by pasteurization performed at 70° C. to 75° C. for 10 to 30 seconds without microfiltration or physical separation of microorganism in the skimmed milk fraction;
- b. subjecting the skimmed milk fraction to a heat treatment, said heat treatment comprising heating the skimmed milk fraction to 152° C. to 165° C. for a time of 500 ms or less;
- and
- c. flash cooling of the skimmed milk fraction to a temperature at or below 70° C.
A process for producing a skimmed milk fraction comprising the steps of:
- a. separating a whole milk into a cream fraction and a skimmed milk fraction having a fat content of 0.05%-0.5% by weight and pre-treating the skimmed milk fraction by pasteurization performed at 70° C. to 75° C. for 10 to 30 seconds directly after the separating;
- b. heating the skimmed milk fraction to 152° C. to 165° C. for a time of 500 ms or less directly after the pre-treating;
- and
- c. cooling of the skimmed milk fraction to a temperature at or below 70° C.
