Shelf stable, concentrated, liquid flavorings and methods of preparing beverages with the concentrated liquid flavorings
Concentrated liquid flavorings and methods of preparing flavored beverages using the concentrated liquid flavorings are described herein. The concentrated liquid flavorings are shelf stable for prolonged storage times at ambient temperatures. Shelf stability is provided, at least in part, by acidic pH and/or reduced water activity. By one approach, the concentrated liquid flavorings are intended to provide flavor to a beverage, such as coffee, tea, milk, or other savory beverage. The concentrated liquid flavorings may be provided in a convenient portable and dosable format that can be easily used by a consumer to provide the desired flavor and amount of flavor to a beverage.
1. A method of preparing a flavored beverage using a concentrated acidic liquid flavoring without causing curdling in the flavored beverage, the method comprising:
dispensing a jet of concentrated acidic liquid flavoring into a beverage from a container having a nozzle, the nozzle configured to provide a mass flow between 1.0 g/s and 5 g/s to rapidly mix the concentrated acidic liquid flavoring with the beverage without causing curdling in the beverage, wherein the beverage includes a protein-containing liquid, and the concentrated acidic liquid flavoring comprises:
about 10 to about 45 wt. percent water;
about 3 to about 40 wt. percent flavor component; and
less than about 2.0 wt. percent acidulant, the amount of acidulant effective to provide the concentrated liquid flavoring with a pH of about 3.8 to about 4.5, and
wherein the concentrated acidic liquid flavoring is dispensed into the beverage to dilute the concentrated acidic liquid flavoring by a factor of about 40 to about 160 times.
2. The method of claim 1 , wherein the mixing of the beverage and the concentrated acidic liquid flavoring with the jet includes mixing the beverage and the concentrated acidic liquid flavoring into a generally homogenous mixture having a delta pH of 0.3 between the bottom and the top of the beverage in a target container within 10 seconds of the jet impacting the beverage.
3. The method of claim 1 , wherein the mixing of the beverage and the concentrated acidic liquid flavoring with the jet produces a Mixing Ability Value of less than 3.
4. The method of claim 1 , wherein dispensing the jet of the concentrated acidic liquid flavoring from the container through the nozzle has a mass flow between 1.0 g/s and 5 g/s and includes dispensing a dose of the concentrated acidic liquid flavoring within 0.3 seconds to 3.0 seconds.
5. The method of claim 1 , wherein the nozzle is configured to provide a mass flow between 1.0 g/s and 1.5 g/s.
6. The method of claim 1 , wherein the flavoring further comprises less than about 30 wt. percent non-aqueous liquid.
7. The method of claim 1 , wherein the flavor component comprises one or more flavor keys and the total amount of flavor key in the concentrated acidic liquid flavoring is about 0.1 to about 10.0 percent flavor key by weight of the flavoring.
8. The method of claim 1 , wherein the flavoring has a pH of about 4.0 to about 4.5.
9. The method of claim 1 , wherein the flavoring has a pH of about 4.0 to about 4.2.
10. The method of claim 1 , wherein the protein-containing liquid is a dairy liquid and/or dairy milk substitute.
11. The method of claim 10 , wherein the dairy liquid comprises at least one of milk, cream, half and half, and dairy creamer.
12. The method of claim 10 , wherein the dairy milk substitute comprises at least one of almond milk or soy milk.
13. The method of claim 10 , wherein a squeeze force of 40-100 inch WC on the container produces a mass flow of concentrated acidic liquid flavoring of 1.0-1.5 g/s.
14. The method of claim 10 , wherein the concentrated acidic liquid flavoring comprises about 0.02 wt. % to about 1.0 wt. % acidulant.
15. The method of claim 10 , wherein the concentrated acidic liquid flavoring comprises one or more flavor keys and the total amount of flavor keys is about 0.1 wt. % to about 20 wt. %.
16. A method of preparing a flavored beverage using a concentrated acidic liquid flavoring without causing curdling in the flavored beverage, the method comprising:
dispensing a jet of concentrated acidic non-dairy liquid flavoring into a beverage from a container having a nozzle, the nozzle configured to provide a mass flow between 1.0 g/s and 5 g/s to rapidly mix the concentrated acidic liquid flavoring with the beverage without causing curdling in the beverage, wherein the beverage comprises a dairy liquid;
wherein the concentrated acidic liquid flavoring comprises about 10 to about 45 wt. percent water, about 3 to about 40 wt. percent flavor component comprising about 0.1 wt. % to about 20 wt. % flavor key, and less than about 2 . 0 wt. percent acidulant, the amount of acidulant effective to provide the concentrated liquid flavoring with a pH of about 3.8 to about 4.5.
17. The method of claim 16 , wherein a squeeze force of 40-100 inch WC on the container produces a mass flow of concentrated acidic liquid flavoring of 1.0-1.5 g/s.
18. The method of claim 17 , wherein the jet of concentrated acidic liquid flavoring is dispensed for 0.3-3 seconds.
19. The method of claim 16 , wherein the concentrated acidic liquid flavoring is dispensed into the beverage to dilute the concentrated acidic liquid flavoring by a factor of about 40 to about 160 times.
