Definitions
- the present invention relates to coffee beverages, and particularly, although not exclusively, to novel methods for preparing coffee beverage products, and to the beverage formulations themselves, which are provided in a positive pressure container in which they are sold to consumers.
- Coffee beverages are widely consumed, and are refreshing drinks with a distinct aroma and flavour.
- Coffee is prepared from the roasted seeds or beans of the Coffea plant, which is a member of the Rubiaceae family, and several species of Coffea are grown for the beans.
- Coffea arabica accounts for about 80% of the world’s coffee production, while Coffea canephora accounts for about 20%.
- the coffee bean is a seed of the coffee plant, and is primarily the source of the coffee flavour.
- Ready-made or ready-to-drink (RTD) hot and cold coffee beverages are now available for purchase by consumers, and are conveniently packaged in an easy-to-open container, such as a can or tin, or the like.
- the container may be made of steel which is a tough and resilient material. For some coffee beverages, particularly canned coffee containing milk, there is a risk of explosion, and so they may be placed under a small negative internal pressure in order to reduce this risk.
- the container may be made of aluminium, which is much lighter and less robust than steel, and so is prone to denting or otherwise being damaged, either in its outer casing or in or along its seals. Accordingly, in order to provide strength and prevent damage to aluminium containers, and also to facilitate the identification of any fails in their seals, aluminium containers or cans are subjected to a small positive internal pressure.
- RTD ready-to-drink
- the present invention arises from the inventors’ work in attempting to overcome the problems associated with the prior art.
- the inventors carried out research into the various steps involved in the production of ready-to-drink (RTD) coffee beverages, and surprisingly found that it is possible to reduce and even prevent foaming to acceptable levels during the process by carefully selecting temperatures to which the beverage ingredient combinations are exposed throughout the process, namely a blending step, a homogenisation step and a filling step.
- RTD ready-to-drink
- a process for producing a ready-to-drink (RTD) coffee beverage contained in a positive pressure container comprising:
- a ready-to-drink (RTD) coffee beverage obtained, or obtainable, by the process of the first aspect.

- the coffee solids of the coffee component can be measured by determining the solid content of the coffee extract (including a solution in which coffee extract and/or powder coffee was dissolved) as a raw material from the sugar refractometer reading (Brix value) at 20°C.
- a sugar refractometer RFM340+, manufactured by Bellingham+Stanley
- RFM340+ can be used to measure the sugar refractometer reading (Brix value) of the coffee extract, and after multiplied by the amount of coffee extract (g), the coffee solid content (g) in the composition can be calculated.
- the inventors have investigated the processing methods for both white coffee beverages (i.e. containing milk as in the first and second aspects) and also black coffee beverages (i.e. without milk), and appreciate that it is not necessary for the method to include a homogenisation step for black coffee in order to reduce foaming. Furthermore, they were surprised to observe that the optimum temperatures for the blending and filling steps for black coffee were significantly different to those used for white coffee.

- a method of preparing a ready-to-drink (RTD) coffee beverage product comprising: (i) introducing a beverage composition into a container, wherein the composition comprises a flavour component, and an emulsifier having a hydrophilic-lipophilic balance (HLB), which is greater than 10; and (ii) maintaining the composition under a positive internal pressure, to thereby prepare the beverage product.
- HLB hydrophilic-lipophilic balance

- the beverage product 4 may be sold cold and is therefore kept refrigerated at about 5°C. However, in other embodiments, the beverage product 4 is sold hot and is therefore heated in an oven and maintained at about 53°C.
- the inventors have developed a novel method for preparing an RTD coffee beverage.
- the very careful selection of temperatures used for each step of the process results in a reduction in the risk of foaming which can negatively affect process speed and efficiency. This is especially true for the blending, homogenisation (when used for Formulations A, B and C) - and filling steps of the method.
- the inventors have created a range of novel RTD beverage formulations based on coffee flavouring from either coffee extract or coffee powder containing low insoluble solids, and an emulsifier having an HLB, which is greater than 10.
- the beverage may or may not include liquid milk, but it does not include any milk powder, which would otherwise repress foaming after ingredient blending and/or can opening.
- anti-forming agents such as carrageenan, silicone, xanthan gum, carboxymethylcellulose
- CMCO hydrophilic-lipophilic balance
- HLB hydrophilic-lipophilic balance
- “Coffee + Water” consists of“coffee component” and“water”, and coffee extract and/or coffee powder is/are used as a coffee component.
