Aerated frozen confectionary product

1. A method for preparing an aerated frozen confection, the method comprising:

preparing a base mix comprising from 0.5 to 20% fat, from 5 to 15 wt % milk solids-non-fat, from 5 to 35 wt % of a sweetening agent, and up to 6 wt % of a stabilizer, the base mix further comprises 0.1 to 0.5 wt % of natural acacia gum that has not been subjected to a physical modification process, has not been subjected to a microbiological or enzymatic process, and has not been subjected to a chemical modification process, wherein the natural acacia gum is the sole emulsifier in the base mix;

homogenizing and pasteurizing the base mix; and

freezing while aerating the homogenized and pasteurized mix to provide an end product with an overrun between 120% and 160%, the natural acacia gum is the sole emulsifier in the aerated frozen confection that is the end product, the aerated frozen confection comprises protein-fat aggregates, and 10 to 50% of the protein-fat aggregates by volume have a D[3,2] between 2.28 and 30 microns, wherein the aerated frozen confection is selected from the group consisting of ice cream, mellorine, frozen yogurt, frozen beverage, milk shake, frozen mousse, frozen fudge, and frozen custard.

2. The method of claim 1 , wherein the pH of the base mix is adjusted to a value between 5.8 and 6.3.

3. The method of claim 1 , wherein the mix comprises up to 6% fat, the freezing of the mix while aerating is followed by cooling the frozen mix to a temperature below −11° C. in an extruder, and the overrun provided in the end product is between 120 and 140%.

4. The method of claim 3 , wherein the extruder is a twin screw extruder.

5. The method of claim 1 , further comprising an acidification step before the pasteurizing.

6. The method of claim 5 , wherein the acidification step adjusts the pH of the base mix to a value between 5.8 and 6.3.

7. The method of claim 1 , wherein the homogenizing comprises a two-stage homogenizing process.

8. The method of claim 1 , wherein the stabilizer is selected from the group consisting of pectin, guar gum, locust bean gum, tara gum, xanthan gum, arabic gum, quillaia gum, agar and mixtures thereof.

9. The method of claim 8 , wherein the base mix consists of the fat, the milk solids-non-fat, the sweetening agent, the stabilizer, and the natural acacia gum.

10. The method of claim 1 , wherein the fat is 0.5 wt. % to 5.5 wt. % of the base mix and is selected from the group consisting of fresh cream, sour cream, cultured cream, butter, concentrated butter, cocoa butter, coconut oil, hazelnut oil, palm oil, palm kernel oil, canola oil, soybean oil, sunflower oil and mixtures thereof.

11. The method of claim 1 , wherein the milk solids-non-fat is between 9 wt. % and 12 wt. % of the base mix.

12. The method of claim 1 , wherein the protein-fat aggregates are formed in situ during processing of the base mix.

13. The method of claim 1 , wherein the aerated frozen confection comprises up to 6% fat, and an average equivalent diameter (D 21 ) of fat globules or fat globule agglomerates is less than 10 microns.

14. The method of claim 1 , wherein the overrun of the aerated frozen confection is between 125% and 160%.

15. A method for preparing an aerated frozen confection, the method comprising:

preparing a base mix comprising from 0.5 to 20% fat, from 5 to 15 wt % milk solids-non-fat, from 5 to 35 wt % of a sweetening agent, and up to 6 wt % of a stabilizer, the base mix further comprises 0.1 to 0.5 wt % of natural acacia gum that has not been subjected to a chemical modification process, wherein the natural acacia gum is the sole emulsifier in the base mix;

homogenizing and pasteurizing the base mix; and

freezing while aerating the homogenized and pasteurized mix to provide an end product with an overrun between 120% and 160%, the natural acacia gum is the sole emulsifier in the aerated frozen confection that is the end product, the aerated frozen confection comprises protein-fat aggregates, and 10 to 50% of the protein-fat aggregates by volume have a D[3,2] between 2.28 and 30 microns, and wherein the aerated frozen confection is selected from the group consisting of ice cream, mellorine, frozen yogurt, frozen beverage, milk shake, frozen mousse, frozen fudge, and frozen custard.

16. The method of claim 15 , wherein the pH of the base mix is adjusted to a value between 5.8 and 6.3.

17. The method of claim 15 , wherein the mix comprises up to 6% fat, the freezing of the mix while aerating is followed by cooling the frozen mix to a temperature below −11° C. in an extruder, and the overrun provided in the end product is between 120 and 140%.

18. The method of claim 15 , wherein the stabilizer is selected from the group consisting of pectin, guar gum, locust bean gum, tara gum, xanthan gum, arabic gum, quillaia gum, agar and mixtures thereof.

19. The method of claim 18 , wherein the base mix consists of the fat, the milk solids-non-fat, the sweetening agent, the stabilizer, and the natural acacia gum.
