Abstract
A dairy based cheese food is prepared by a process involving heating milk to pasteurize and denature whey proteins, acidifying the milk to form curd and whey, separating the curd from the whey, neutralizing the curd by adding a base, mixing an acid with the neutralized curd to reacidify, mixing an additive with the curd, manipulating the curd such as by extrusion, and packaging the curd.
Claims4
A process for production of a dairy-based cheese food which comprises the steps of:
- A. preparing a milk formulation of fat content from about 2 to 3.5%,
- B. heating the milk to pasteurize the same and to denature the proteins,
- C. acidifying the milk while still heated and with agitation to between about pH 4.2 and 5.1 to form curd particles,
- D. while maintaining the pH, separating the curds from the resulting whey,
- E. mixing a base with the curds to neutralize the same to between about pH 6.5 and 9 to solubilize the proteins,
- F. mixing an acid with the neutralized curds to reacidify to about pH 5.3,
- G. during mixing introducing at least one additive selected from the group consisting of coloring agents, flavoring agents, stabilizers and preservatives,
- H. manipulating the curds during mixing, and
- I. directly packaging the cheese food product.
