POST-FREEZING ACIDIFICATION OF FROZEN DAIRY PRODUCTS
The invention is directed toward a frozen, aerated dairy product, such as an ice cream, having a pH below 6.0 and methods for preparing such products.
1 . A method for preparing a frozen aerated dairy product, comprising the steps of:
freezing and aerating a mixture comprising MSNF, milk fat, and at least one sweetener;
adding a fruit acid to reduce the pH of the frozen, aerated mixture to a desired pH below 6.0; and
hardening the frozen aerated dairy product
2 . The method of claim 1 , wherein the mixture further comprises an egg component.
3 . The method of claim 2 , wherein the frozen aerated dairy product further comprises fruit or fruit pieces.
4 . The method of claim 3 , wherein the fruit acid is obtained from a citrus fruit.
5 . The method of claim 4 , wherein fruit acid is concentrated lemon juice added to a level of 0.25% to 2% by weight of the frozen aerated dairy product.
6 . A frozen aerated dairy product having a pH below 6.0, comprising a mixture comprising MSNF, milk fat, at least one sweetener, and at least one egg component, the product further comprising a fruit acid added to the mixture after freezing of the mixture, the fruit acid added in an amount sufficient to lower the pH of the mixture to a desired pH below 6.0.
7 . The frozen aerated dairy product of claim 6 , wherein the frozen aerated dairy product is an ice cream.
8 . The frozen aerated dairy product of claim 7 , wherein the frozen aerated dairy product further comprises fruit or fruit pieces.
9 . The frozen aerated dairy product of claim 8 , wherein the fruit acid is derived from a citrus fruit.
10 . The frozen aerated dairy product of claim 9 , wherein the fruit acid is concentrated lemon juice.
