Detailed Description of the invention

[0020] The present invention provides an instant or ready-to-drink beverage containing milk solids that may be heated without resulting in a scalded milk type of flavor, aroma or taste. The beverage will typically be a reduced or low-fat composition. [0021] More specifically, the present invention provides a high quality instant or ready-to-drink beverage comprising (1) milk solids; (2) a fat component; (3) a beverage base such as coffee extract solids, spray dried coffee, or tea solids or extract or cocoa; and (4) water, wherein the beverage does not result in a scalded milk flavor upon

heating. The beverage may further comprise potassium salt pH adjustors, thickeners and/or stabilizers, a sweetener component, vitamins and/or minerals, flavor components or mixtures thereof. Additionally, the beverage may be suitable for long-term storage in bulk or individual-sized containers.

[0022] The ready-to-drink beverage typically has an overall density of between

1.0-1.1 g/cc, and more preferably between 1.04-1.08 g/cc. The total solids of the beverage are typically between approximately 8-15% by weight of the total beverage. [0023] The combination of milk solids, a fat component, coffee or tea or coffee/tea solids or cocoa (for hot chocolate), sweeteners, and optional flavors results in the production of a superior quality ready-to-drink beverage product that can be heated without resulting in a scalded milk flavor, providing both superior taste and mouthfeel properties. Reducing the amount of the fat component and adding from a variety of vitamins or minerals further provides a superior quality ready-to-drink beverage that has nutritional benefits.

[0024] The milk solids may be from any source of milk solids, such as condensed milk (whole, reduced-fat or skim milks) or powdered milks. These solids can also include butterfat solids and cream powder. Preferably, liquid condensed skim milk is the source of the milk solids. Most preferably, powdered non-fat milk solids are used having a fat content of less than about 0.5% by weight as determined by the Roese- Gottlieb method. The non-fat milk solids in the beverage composition may be in the range of approximately 2.0-5.4%, preferably between approximately 4.5-5.4%, more preferably between approximately 5.0-5.4%, and most preferably between approximately 5.1-5.4% by weight of the entire ready-to-drink beverage. [0025] The fat component may be from any suitable source of fat, such as dairy fat, non-dairy fat or mixtures thereof. Preferably, the fat component is from a dairy fat, for example from heavy cream, light cream, half and half, milk (whole, reduced-fat or iow-fat milks), or evaporated or dried versions of the same or mixtures thereof. The dairy fat may be fresh, pasteurized or unpasteurized. The fat component may also come from other non-dairy sources such as vegetable oils, coconut oils, oils found in

cocoa or coffee, oils from other plant sources or mixtures thereof. Minor amounts of fat may come from non-fat condensed skim milk, for example.

[0026] The fat component may be from approximately 0.8-4.0%, more preferably from approximately 0.8-2.0%, and most preferably from approximately 0.8-1.1% by weight of the entire ready-to-drink beverage. Increasing the fat component aids in avoiding the scalded milk flavor taste of the beverage, while reducing the fat component results in a healthier and more nutritious beverage. It is most preferable to have a low fat content in the range of 0.8-1.1% and wherein the beverage does not result in a scalded milk type of flavor, aroma or taste upon heating or reheating. [0027J As those skilled in the art will realize, the milk solids and the fat component may be derived from the same dairy components or from separate dairy components or from other components as described.

Most preferably, the beverage comprises between approximately 5.1-5.4% by weight powdered non-fat milk and between approximately 0.8-1.1% fat by weight, the great majority of which is from heavy cream. [0029] The beverage base may be in any form of coffee or tea, for example. The beverage may comprise coffee, which can be present as, for example, coffee extract solids, concentrated coffee extract solids, spray dried coffee, fresh-brewed coffee and espresso. The tea may be present as, for example, tea solids, concentrated tea solids, spray dried tea or fresh-brewed tea. Preferably, the beverage base is concentrated coffee extract solids. The coffee extract solids may be from approximately 0.75-1.5%, more preferably from 0.79-1.25%, and most preferably from 0.95-1.0% by weight of the entire beverage. The tea can be present in an amount as desired. [0030] The ready-to-drink beverage further comprises water. The water is between approximately 80-95%, more preferably between approximately 85-92%, and most preferably between approximately 85-90% by weight of the total beverage. [0031] The beverage may further comprise water-soluble potassium salts utilized to adjust the pH. The potassium salts are not limited to any particular potassium salt so

long as they are water-soluble, such as potassium carbonate, dipotassium hydrogenphosphate, potassium dihydrogenphosphate, tripotassium phosphate, potassium hydroxide, potassium lactate, potassium tartrate, potassium succinate, potassium malate, potassium citrate, potassium fumerate and mixtures thereof. A preferred potassium salt is a mixture of tripotassium phosphate and potassium carbonate. The pH of the finished beverage is typically between approximately 6.45 and 7.65. The potassium salt(s) may be present in an amount of from about 0.09% to about 0.2% by weight of the total composition.

[0032] The beverage may further comprise a thickening agent. Thickening agents can include maltodextrins, pectins, natural and synthetic gums and natural or chemically modified starches or mixtures thereof. The thickening agent should be easily water-soluble. Preferably, a combination of maltodextrin and pectin are used. Most preferably, maltodextrin with a dextrose equivalent of approximately 9-12% is used in combination with a high ester citrus pectin.

[0033] The beverage may comprise a sweetener or a combination of sweeteners.

The sweetener(s) may be any sweetener(s) normally used in food processing, either natural or artificial, for example sugar alcohols and sugars such as sucrose, fructose, dextrose, maltose, lactose, high fructose corn syrup solids, sorbitol, or mixtures thereof. The sweetener(s) may comprise any suitable synthetic or natural sweetener, which may be a higher intensity sweetener and used in combination with the sugar or sugar alcohol. Examples of such sweeteners include, for example, sucraiose, acesuifame potassium, and mixtures thereof. The sweetener may further comprise a mixture of natural or synthetic sweeteners, such as a sugar or sugar alcohol, used in combination with, for example, a high intensity sweetener. Any mixture or combination of natural or artificial sweeteners may be used. Other sweeteners normally used in food or beverage processing can be used if desired.
