Abstract
An acidified dairy cream characterized by a non-grainy texture and the absence of cooked flavors is made by acidifying dairy-derived cream to a pH level of approximately 4.6 or below. The cream is then heated to a range of 222.degree. F. to 264.degree. F. while being subjected to a pressure of at least approximately 180 psig. The cream is then aseptically packaged.
Claims20
A method for processing an acidified dairy-derived cream, the method comprising:
- providing an acidified dairy-derived cream having a pH level below approximately 4.6;
- heating the cream to a temperature range of approximately 222.degree. F. to 264.degree. F. while simutaneously subjecting the cream to a pressure of at least approximately 180 psig for a time period sufficient to extend ambient temperature shelf life to at least four weeks;
- and
- aseptically packaging the cream.
A method for processing an acidified dairy-derived cream, the method comprising:
- providing an acidified dairy-derived cream having a pH level below approximately 4.6;
- sterilizing the cream within a temperature range of approximately 222.degree. F. to 264.degree. F. while simultaneously subjecting the cream to a pressure of at least approximately 180 psig;
- aseptically packaging the cream;
- and
- wherein the resulting packaged cream has at least a six month shelf life and retains the organoleptic properties of the initial acidified dairy-derived cream.
A continuous process for sterilizing an acidified, dairy-derived, cream product having a pH less than 4.6, in preparation for aseptic packaging, the process comprising:
- heating the product to a temperature within the range of approximately 222.degree. F. to 264.degree. F. while simultaneously subjeting the product to a pressure within the range of approximately 180 psig to 200 psig for a detention time within the range of approximately 2 to 3 seconds;
- and
- homogenizing through a back pressure valve sufficient to generate the requisite pressure and detention time in the sterilization step.
