Embodiment 1

[0070] A non-aqueous fluid coffee concentrate composition "A" (100% by weight) was prepared by spoon stirring spray-dried soluble coffee powder (Robusta; 33% by weight) in NAL (propylene glycol; 67% by weight). The mixture was then heated in a microwave oven at full power for a total of 1 minute to a temperature of 180°F while moving the mixture every 10 seconds and stirring with a spoon to effectively dissolve or disperse all of the coffee in the NAL.

[0071] A comparative non-aqueous coffee concentrate composition "B" (100% by weight) was prepared by spoon stirring the same spray-dried soluble coffee powder (Robusta; 33% by weight) in distilled water (67% by weight). The mixture was then heated in a microwave oven at full power to a temperature of 180°F, followed by stirring with a spoon for 1 minute to dissolve all coffee solids in the water.

[0072] The two coffee concentrates were stored at 37 °C for 30 days in 20 mL capped glass vials under air headspace. Concentrates...

Embodiment 2

[0074] Non-aqueous fluid coffee concentrate "A" (100% by weight) was prepared by spoon stirring spray-dried soluble coffee powder (Robusta; 33% by weight) in NAL (propylene glycol; 67% by weight). The mixture was then heated in a microwave oven to a temperature of 200°F and held at that temperature for 10 minutes while stirring with a spoon to dissolve or disperse all of the coffee in the NAL.

[0075] Comparative non-aqueous fluid coffee concentrate "B" (100% by weight) was prepared by spoon stirring spray-dried soluble coffee powder (Robusta; 33% by weight) in NAL (1,3-propanediol; 67% by weight) . The mixture was then heated in a microwave oven to a temperature of 200°F and held at that temperature for 10 minutes while stirring with a spoon to dissolve or disperse all of the coffee in the NAL.

[0076] The two coffee concentrates were stored at 37 °C for 10 days in 20 mL capped glass vials under air headspace. The product was removed from storage and added individually to...

Embodiment 3

[0078] Fluid non-aqueous coffee concentrate "A" (100% by weight) was prepared as follows: At room temperature, in NAL (caprylic / capric triglycerides, NEOBEE M-5™, available from Stepan Co., Northfield, IL; 67% Spray-dried soluble coffee powder (Robusta; 33% by weight) was manually agitated in 2 wt. %, and the mixture was subsequently subjected to high-shear mixing using a rotor-stator type mixer (Heidolph: Silent Crusher-M, at 50,000 rpm) to Grinds and disperses coffee in a smooth and homogeneous suspension.

[0079] Fluid coffee concentrate "B" (100% by weight) was prepared by spoon-stirring spray-dried soluble coffee powder (Robusta; 33% by weight) in distilled water (67% by weight) at room temperature. The mixture was then mixed using a rotor-stator type mixer (Heidolph: Silent Crusher-M at 50,000 rpm) to grind and dissolve all coffee solids in a smooth homogeneous solution.

[0080]Store both concentrates at 37 °C for 30 days in 20 mL capped glass vials under air headspac...

Abstract

Liquid brewed beverage concentrates and methods of making the concentrates are provided herein. The concentrates are liquid and flowable at room temperature and can be diluted in an aqueous liquid to provide a beverage having the general appearance, flavor, and aroma of a freshly brewed beverage. The concentrates include a low water content, high non-aqueous liquid content, particularly non-volatile non-aqueous liquid content, and high flavor solids content, the amounts of which are balanced to provide concentrates with a desired flavor profile with little or no flavor degradation after storage at room temperature in a sealed container for at least about three months.

Description

field of invention [0001] The present disclosure relates to shelf-stable liquid beverage concentrates, and in particular, the present disclosure relates to shelf-stable, brewed beverage concentrates suitable for dilution with potable liquids for preparing coffee and / or tea beverages. Background of the invention [0002] Commercially available coffee concentrates are usually manufactured by partially dehydrating aqueous extracts of solid flavor sources. Alternatively, such products are manufactured by dissolving the dried extract in water. These products typically undergo heat treatment and / or are fortified with chemical preservatives to improve microbial stability and increase shelf life. [0003] Liquid aqueous coffee concentrates have been commercially available for decades, but these products still suffer from widely known disadvantages related to their composition and handling requirements. For example, the initial aroma quality may be substantially inferior to that of...
