Surprisingly, one embodiment of the invention is a reduced-calorie, freezable beverage that can be adequately slushed using a standard soft-serve ice cream machine. Freezable coffee beverages and fruit beverages that are reduced-calorie, sugar-free, and low-fat are preferred embodiments of the invention.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Divisional of application Ser. No. 10/628,383, filed on Jul. 29, 2003, which claims priority to application Ser. No. 60/399,437, wherein the contents of these two earlier applications are incorporated by reference in their entirety.

FIELD OF THE INVENTION

The invention relates to reduced-calorie, freezable beverages and sugar-free creamers that can be used therewith.

BACKGROUND OF THE INVENTION

There is great demand for products that are low-calorie, low sugar (or sugar-free), and/or low fat. Manufacturing “frozen” drinks with such properties, however, has not yet been successfully achieved.
Commercially available frozen coffee drinks, for example, are typically made using a coffee concentrate that is diluted with water then “slushed” in a machine, such as a soft-serve ice cream machine. The product can then be consumed alone or with a creamer.
These soft-serve ice cream machines typically require a minimum of 11-12° Brix. Brix is the percentage of soluble solids, which are commonly sugars. A high Brix value is associated with depressing the freezing point of the beverage. Typically, a low molecular weight sugar alcohol, such as sorbitol, is added to depress the freezing point of the beverage. Unfortunately, however, sorbitol adds a substantial amount of calories to the beverage. Thus, there is a need for a palatable frozen beverage that is low in calories.

DETAILED DESCRIPTION OF THE INVENTION

The invention is directed to freezable beverages, such as frozen coffee or tea drinks, smoothies, slushies, bar mixes, ice cream products, and the like; as used herein, the term “beverage” is used broadly to cover these types of products. As used herein, the term “fruit” includes fruit solids and fruit juice.
One embodiment of the invention is a 3× concentrate that can be diluted and slushed prior to consumption. The concentrate contains water, a sweetener (preferably a reduced-calorie and/or high potency sweetener such as Sucralose, Acesulfame K, Aspartame, Neotame, Saccharin, etc.), a sugar substitute (such as polyols such as sorbitol, lactitol, maltitol, xylitol, mannitol, etc.), and one or more consumable alcohols (preferably ethanol). Generally, the concentrate will also contain flavoring agents (such as fruit, coffee extracts, tea extracts, etc.), coloring agents (such as caramel color), and texture modifiers (such as carboxymethylcellulose, pectin, carrageenan, guar gum, locust bean gum, xanthan gum, etc.) to control ice crystal growth and/or to modify texture. Other common ingredients that can be used are those well known in the art, such as antifoam agents.
Preferably, the 3× concentrate contains about 0.01-0.4% high potency sweetener, preferably about 0.02-0.4%, preferably about 0.03-0.2%, preferably about 0.05-0.2%; about 1-30% flavoring, preferably about 2-18%, preferably about 2-15%; about 1-35% sugar substitute, preferably about 1-32%, preferably about 1 to about 25%, preferably about 1 to about 9%, preferably about 1 to about 4%; about 0.3-12% alcohol, preferably about 1-10%, preferably about 1 to about 6% (for alcoholic beverages, preferably about 4-10%; for non-alcoholic beverages, preferably less than about 3%, preferably less than about 1.5%).
In a preferred coffee-flavored embodiment of the 3× concentrate, the flavoring comprises coffee extract. In addition, a preferred coffee-flavored embodiment contains preferably about 0.0001-0.001% antifoam agent, preferably about 0.0002-0.0006%; preferably about 0.01-3% texture modifier, preferably about 0.08-0.5%, and/or preferably up to about 1% salt, preferably up to about 0.6%. As used herein, “salt” refers to edible salts, preferably sodium chloride.
In a preferred smoothie embodiment, a 2× concentrate preferably contains about 0.01-0.4% high potency sweetener, preferably about 0.02-0.4%, preferably about 0.02-0.2%, preferably about 0.05-0.2%; about 1-60% fruit, preferably about 3-40%, preferably about 12-22%; about 1-25% sugar substitute, preferably about 2 to about 10%; about 0.2-12% alcohol, preferably about 1-10% (for alcoholic beverages, preferably about 4-10%; for non-alcoholic beverages, preferably less than about 3%, preferably less than about 1.5%). In a particularly preferred smoothie embodiment preferably contains about 0.01-3% texture modifier, preferably about 0.02-0.1%; preferably about 0.01-1% salt, preferably about 0.02-1%; and/or preferably about 0.05-2% additional flavoring, preferably about 0.1-1.2%.
Alternatively, the concentrate could range from just over 1× to 5× or greater. The relative amounts of each ingredient could be easily recalculated accordingly.
Preferably, the concentrate is aseptically manufactured and shelf-stable at room temperature until opened when ready for use.
Another embodiment of the invention is a freezable beverage comprising a concentrate that has been diluted to a palatable beverage. For a 3× concentrate, 1 part concentrate would be added to about 2 parts water. The freezable beverage comprises an effective amount of alcohol to produce a beverage that can be slushed using machines commonly used in the art for such purpose. Preferably, the amount of alcohol is about 0.2-1%. For some applications, the amount of alcohol used is preferably less than 0.5%, thereby qualifying the product as “alcohol free” according to certain governmental regulations. However, if the freezable beverage is intended as an alcoholic beverage, then more than 0.5% alcohol may be desirable.
Generally, within the alcohol range of 0-0.5%, the higher part of this range is preferred because less other soluble solids, such as sugar alcohols, is then required to achieve adequate slushing. Preferably, a coffee beverage embodiment, for example, contains about 0.1-0.5% alcohol, more preferably about 0.2-0.5% alcohol, more preferably about 0.3-0.5%.
Preferred embodiments of the freezable beverage of the invention are low in calories, preferably less than 12.5 calories/oz, more preferably less than about 10 calories/oz, more preferably less than about 8 calories/oz, more preferably about 7 calories/oz or less.
Typically, the low-calorie, freezable beverage will have a low Brix value, such as less than about 10° Brix, preferably less than about 7° Brix, and more preferably as low as 3° Brix or lower. Advantageously, a freezable beverage with a lower Brix value is generally lower in calories. Surprisingly, a preferred embodiment of the invention has a lower Brix value than the equipment manufacturer's assumptions for what is required to produce an adequate slush in their equipment, which is generally at least 11-12° Brix. Preferably, the various composition embodiments of the invention are made aseptically.
Another embodiment of the invention is a creamer, preferably sugar-free, that can be mixed with the freezable beverage. The freezable beverage, however, can be used alone or with other creamers. The use of skim milk, for example, would largely retain the benefit of a low calorie product. Preferably, I part creamer is mixed with about 3 parts slushed beverage.
Preferably, the creamer contains water; about 0.1-10% emulsifier, more preferably about 2.5-5%; about 0.001-2% stabilizer, more preferably about 0.02-1%; about 1-15% sweetener (preferably a sugar substitute), more preferably about 3-8%; about 0.01-25% fat, preferably about 0.01-12%, more preferably about 0.1-3%. In a preferred embodiment, the creamer also contains 0.0001-0.01% antifoam agent, more preferably 0.0002-0.005%; about 0.001-1.0 flavoring, more preferably 0.01-0.2%; and about 0.01-0.8% stabilizer salt; more preferably about 0.03-0.1%.
Suitable emulsifiers include, for example, mono and diglycerides, sodium stearoyl lactylate, sucrose esters, DATEM, or other known emulsifiers. Suitable sugar substitutes include, for example, polyols such as sorbitol, lactitol, maltitol, xylitol, mannitol, etc. Suitable fats include animal-based fats, such as butterfat, or, preferably, vegetable oils, such as palm kernel oil, butterfat, coconut oil, soybean oil, canola oil, sunflower oil, etc. Other common ingredients that can be used are those well known in the art, such as antifoam agents and salts.
The present invention will now be described in detail with respect to showing how certain specific representative embodiments thereof may be made, apparatus and process steps being understood as examples that are intended to be illustrative only. In particular, the invention is not intended to be limited to the methods, ingredients, conditions, process parameters, apparatus and the like specifically recited herein.
